Intended Use  
The scanner units detailed in this handbook form part of navigational radar  
systems intended for light marine use. These radar systems are only an aid to  
navigation.  
Safety Notices  
This radar equipment must be installed and operated in accordance with the  
instructionscontained in this manual. Failure todo socanresult inpersonal injury  
and/or navigational inaccuracies. In particular:  
1. High Voltage. The scanner unit contains high voltages. Adjustments require  
specialized service procedures and tools only available to qualified service  
technicians – there are no user serviceable parts or adjustments. The operator  
should never remove the scanner unit internal covers or attempt to service the  
equipment.  
2. Electromagnetic Energy. The radar scanner transmits electromagnetic  
energy. It is important that the radar is turned off whenever personnel are  
requiredtocomeclosetothescannertoperform workonthescannerassemblyor  
associated equipment.  
It is recommended that the radar scanner is mounted out of range of personnel  
(above head height).  
Do not look directly at the antenna at close range as your eyes are the most  
sensitive part of the body to electromagnetic energy.  
When properly installed and operated, the use of this radar will conform to the  
requirementsofANSI/IEEEC95.1-1992StandardforSafety LevelswithRespectto  
Human Exposure to Radio Frequency Electromagnetic Fields, 3 Hz to 300 GHz and  
NRPB, Board Statement on Restrictions on Human Exposure to Static and Time  
Varying Electromagnetic Fields and Radiation, Doc NRPB, No. 5 (1993).  
3. Navigation Aid. This radar unit is only an aid to navigation. Its accuracy can  
be affected by many factors, including equipment failure or defects,  
environmental conditions, and improper handling or use. It is the user’s

Preface  
This handbook describes the following Raymarine Pathfinder radar scanners:  
5S  
7S  
9S  
11S  
48" 4 kW Open Array Scanner  
72" 4 kW Open Array Scanner  
48" 10 kW Open Array Scanner  
72" 10 kW Open Array Scanner  
These scanner units may be connected to any HSB/hsb2 or C-Series display unit.  
The open array scanners must not be used with the SL70, SL70  
PLUS, SL70RC PLUS or Autohelm 7" LCD Display Unit. This may  
result in damage to the display due to the high power  
requirements of the open array scanner.  
The handbook contains very important information on the installation and  
operation of your new equipment. In order to obtain the best results in operation  
and performance, please read this handbook thoroughly.  
Raymarine’s Technical Support representatives or your local dealer will be  
available to answer any questions you may have.  
Display Software Version  
For full operation of the Pathfinder scanners, the display unit requires an  
appropriate software version. For new displays, the correct software version is  
normally already installed in the display unit and is fully compatible with the  
Pathfinder scanners.  
Early display units may not have the correct software and will therefore require  
upgrading.  
The software version can be confirmed by switching-on the display and checking  
the version number during the magnetron warm-up sequence.  
Note: If a scanner unit is not connected the version number is only displayed for 10 sec-  
onds.  
Where, necessary Software Upgrade Kits are available from your dealer,  
distributor or from Raymarine. We recommend that where a repeater display is  
fitted, both the repeater and the master display are upgraded.  
 
8
C-Series Display Compatibility  
To achieve full compatibility with a C-Series Display, your Raymarine radar  
scanner may require upgrading. Please refer to the C-Series Display Owner’s  
Handbook, or contact Technical Support for details.  
The open array scanners cannot be powered from a C-Series display unit; they  
must be connected to ship’s power using a split pedestal cable or pedestal  
adaptor cable. Full details are provided in this handbook.  
Warranty  
To register your Pathfinder Radar Scanner ownership, please take a few minutes  
to fill out the warranty registration card found at the end of this handbook. It is  
very important that you complete the owner information and return the card to  
the factory in order to receive full warranty benefits.  
The radome scanner package includes a barcode label indicating the serial  
number of the unit. This label should be stuck to the warranty registration card.  
The open array scanner has two barcode labels indicating the serial numbers of  
the pedestal and the antenna units. Both labels should be stuck to the warranty  
registration card.

Chapter 2: Overview  
2.1 Introduction  
This handbook provides instructions to assist you in the installation and set up of  
the following radar scanners:  
5S 48" 4 kW Open Array Scanner  
7S 72" 4 kW Open Array Scanner  
9S 48" 10 kW Open Array Scanner  
11S 72" 10 kW Open Array Scanner  
These scanner units may be connected to any HSB/hsb2 or C-Series display unit.  
Note: To achieve full compatibility with a C-Series Display, your Raymarine radar  
scanner may require upgrading. Please refer to the C-Series Display Owner’s  
Handbook, or contact Technical Support for details.

CAUTION:  
Do not use an open array scanner with an SL70, SL70 PLUS or  
SL70RC PLUS 7" LCD display unit. Failure to observe this may  
result in permanent damage to these display units.  
The 10 kW open array scanner requires 24 V or higher; it will not  
operate on 12 V systems.  
This handbook is divided into three chapters as follows:  
Chapter One provides information to help you plan the scanner installation. It  
includes sections on Unpacking and Inspecting the Components, Selecting the  
Scanner Site, Cable Requirements and Power Requirements.  
Chapter Two provides detailed instructions on how to mount and connect each  
type of scanner.  
Chapter Three provides instructions on how to perform the system checks,  
alignment and adjustments. It also provides information on maintenance and  
what to do if you have problems.  
EMC installation guidelines  
All Raymarine equipment and accessories are designed to the best industry  
standards for use in the leisure marine environment.  
Their design and manufacture conforms to the appropriate Electromagnetic  
Compatibility (EMC) standards, but correct installation is required to ensure that  
performance is not compromised. Although every effort has been takento ensure  
that they will perform under all conditions, it is important to understand what  
factors could affect the operation of the product.  
The guidelinesgiven here describe the conditionsforoptimumEMC performance,  
but it isrecognized thatit may not bepossible tomeetall of theseconditionsin all  
situations. Toensurethebest possibleconditions for EMC performance withinthe  
constraints imposed by any location, always ensure the maximum separation  
possible between different items of electrical equipment.  
For optimum EMC performance, it is recommended that wherever possible:  
Raymarine equipment and cables connected to it are:  
At least 1 m (3 ft) from any equipment transmitting or cables carrying  
radio signals e.g. VHF radios, cables and antennas. In the case of SSB  
radios, the distance should be increased to 2 m (7 ft).  
More than 2 m (7ft) fromthe path of a radar beam. A radar beam cannor-  
mally be assumed to spread 20 degrees above and below the radiating  
element.  
 
clxxxvii  
The equipment is supplied from a separate battery from that used for engine  
start. Voltage drops below 10 V (20 V for 10 kW open array scanners) in the  
power supply to our products, and starter motor transients, can cause the  
equipment to reset. This will not damage the equipment, but may cause the  
loss of some information and may change the operating mode.  
Raymarine specified cables are used at all times. Cutting and rejoining these  
cables can compromise EMC performance and so must be avoided unless  
doing so is detailed in the installation manual.  
If a suppression ferrite is attached to a cable, this ferrite should not be  
removed. Ifthe ferrite needs tobe removedduringinstallationit must be reas-  
sembled in the same position. Section 2.1, Radome scanner includes instruc-  
tions on fitting a ferrite.  
The following illustration shows a typical range of suppression ferrites fitted to  
Raymarine equipment.  
D3548-4  
Connections to Other Equipment  
Ifyour Raymarine equipment is to be connected to other equipment using a cable  
not supplied by Raymarine, a suppression ferrite MUST always be fitted to the  
cable close to the Raymarine unit.  
2.2 Unpacking and inspecting the components  
Unpack your system carefully, to prevent damage to the equipment. It is good  
practice to save the carton and packing for future use, in case you need to return  
the unit for service. Check that you have all the correct system components. These

2.3 Selecting the scanner unit site  
This section provides information that affects the possible locations of the  
scanner, and its position relative to the display unit and to the power supply.  
The dimensions of the each scanner unit are shown in the following diagrams.  
Selecting the best location for the scanner unit requires careful consideration of  
the following points, to ensure reliable and trouble free operation:  
Note: In order to minimize potentialinterferencetoother systemson boardship (EMC), it  
is advisable to mount the scanner on a part of the boat that is insulated from the ship’s bat-  
tery negative. If you cannot do this, and encounter problems, you can fit insulating bushes  
between the scanner and its mounting bracket.  
Height: The scanner unit should normally be mounted as high as practical  
above the waterline, for three reasons:  
For safety reasons the scanner should be out of range of personnel, pref-  
erably above head height. This avoids mechanical danger and electro-  
magnetic contact, particularly with the eyes.  
 
clxxxix  
Radar operates atthe line-of-sight, so ahighmounting position gives bet-  
ter long range performance.  
Surrounding large objects, in the same horizontal plane, can interfere  
with the radar signal and cause blind areas or shadow sectors and false  
targets on the radar screen (see below).  
However, do not mount the scanner so high that it is affected by the pitching  
and rolling of the vessel. In addition, you may need to lower the scanner to  
avoid creating a shadow sector underneath the scanner’s beam.

cxci  
Access: The scanner unit site should be easily accessible to allow mainte-  
nance to be carried out safely.  
Magnetic compass:Mount the scanner unit at least 1 m away from a mag-  
netic compass.  
Cable run: The maximum length of cable between the display unit and the  
scanner unit should not normally exceed 20 m (60 ft) for radome scanners, or  
15 m (45 ft) for open array scanners. If you need to use a longer cable power  
cable lengths must be considered, refer to Section 1.4 Cable Runs to deter-  
mine appropriate lengths.  
Shadow sectors and false echoes: Mount the scanner away from large  
structures or equipment, such as the fly bridge, large engine stacks, search-  
lights, horns, or masts. It is particularly important to avoid shadow sectors  
near the bow. Raising or even lowering the scanner may help to reduce these  
effects.  
In shadow areas beyond the obstruction there will be a reduction of the  
beam intensity, although not necessarily a complete cut-off; there will be a  
blind sector if the subtended angle is more than a few degrees.  
In some shadow sectors the beam intensity may not besufficient to obtain an  
echo from a very small object, even at close range, despite the fact that a  
large vessel can be detected at a much greater range. For this reason the  
angular widthandrelativebearing of any shadow sector must be determined  
at installation. Sometimes shadowing can be seen by increasing the radar  
gain until noise is present. Dark sectors indicate possible shadowed areas.  
This information should be posted near the display unit and operators must  
be alert for targets in these blind sectors.  
It should also be noted that wet sails create shadow areas and thus sail boat  
operators should be aware that radar performance may reduce in rain.  
If you mount the scanner on a mast, echoes from the mast may appear on the  
radar display. These can be minimized by placing absorbing material, such as  
a block of wood, between the scanner and mast.  
Platform rigidity/stability:The scanner platform should not twist (caus-  
ing bearing errors) or be subject to excessive vibration.  
Heat/fumes:Mount the scanner away from the top of exhaust stacks, since  
the scanner and cables can be damaged by excessive heat and the corrosive  
effects of exhaust gases.  
For open array scanners you should also consider the following points:  
 
cxcii  
Mounting Platform: The platform must be mechanically secure and capa-  
ble of supporting the mass and inertia of the open array scanner. The com-  
plete unit weighs: 48" scanner - 30 kg (66.2 lb); 72" scanner - 33.4 kg  
(73.7 lb).  
The site must be clear of ropes and moving rigging.  
Sufficient clearance must be allowed to fully open the openarray pedestal for  
maintenance.  
Mounting surface: sailboats  
The scanner unit can be installed on a mast platform, an arch, or a bridge  
structure. Make sure that the platform surface is flat and the scanner unit drain  
hole (radome scanners) is not obstructed. Raymarine recommends that radome  
scanner units are best suited for sailboat operation as open array systems are  
more difficult to protect from ropes and sails.  
For sailboat installations, Raymarine offers a universal mast mount kit for each  
radome scanner type. This optional mount is used to fit a radome scanner to a flat  
surface on a mast with a minimum diameter of 60 mm (2½ in). When using the  
mast mount kit, appropriate hardware should be used for the style and structure  
ofthe mastaboard the vessel. Typically, the scanner willbemounted nearthefirst  
set of mast spreaders. If there is any doubt concerning the appropriate type of  
hardware, consult your boat dealer or representative for their recommendations.  
Dependingonthe typeofsailboat, aradar scannerguardshould beinstalled ifthe  
sails could touch the scanner or platform. Without a proper radar guard the  
mounting platform and the radar scanner could be severely damaged.  
Mounting surface: power boats  
On many small vessels the scanner unit can be installed on a mast platform, an  
arch, or a bridge structure, but take care to follow the scanner site guidelines,  
particularlyregardingheight. Ifnecessary, constructaradarmountingplatform to  
obtain a sufficiently high mounting position. Make sure that the platform surface  
is flat and the scanner unit drain hole (radome scanners) is not obstructed. Ensure  
the platform is strong enough to supportthe maximum shock loads likely to occur.  
 
cxciii  
Setting the radiation plane  
The scanner unit should be mounted so that the array rotates parallel to the  
waterline. The radar beam is approximately 25° wide in the vertical direction,  
providing good target detection during the vessel’s pitching and rolling.

Planing hull vessels, and some displacement hull vessels, adopt a higher bow  
angle when the vessel is at its cruising speed. In many cases this substantially  
alters andraisesthe radar’smainradiationplane, andcancausepoordetection of  
nearby targets. It may be helpful to lower the radar beam back towards the  
parallel, by shimming the rear of the radar, so that the beam points slightly  
downwards with respect to the waterline when the vessel is at rest.

The shims may be made from aluminium plate wedges, simple flat washers, or an

the M8x40 bolts supplied with the radome scanner, or the M10 studdingsupplied  
with the open array scanners.

2.4 Cable Requirements  
This section provides details on selecting the appropriate cables for your system.  
Permissible cable lengths depend on the scanner type and the boat’s power  
system. Information on inter-unit and power cables is provided for both radome  
and open array scanners in the following sections.  
You need to consider the following before installing the cables:  
You need to connect the scanner to the display unit and to power. The cable  
requireddependsonthedisplayunitandthescannertypeasdescribedbelow.  
All cables should be adequately clamped and protected from physical dam-  
age and exposure to heat - avoid running cables through bilges or doorways,  
or close to moving or hot objects.  
Acute bends must be avoided.  
Where a cable passes through an exposed bulkhead or deckhead, a water-  
tight gland or swan neck tube should be used.  
Avoid cutting and re-joining cables (if necessary, refer to the notes below).  
Scanner Cables  
The cable used to connect your scanner to the display unit and power depends on  
the type of scanner and display as follows:  
A radome scanner connected to a Pathfinder or C-Series display requires an  
inter-unit cable. The scanner receives power via the display unit, the power  
cable is supplied with the display unit but cable details are provided in this  
section.  
AnopenarrayscannerconnectedtoaPathfinderdisplayrequiresaninter-unit  
cable. The scanner receives power via the display unit, the power cable is sup-  
plied with the display unit but cable details are provided in this section.  
An open array scanner cannot be powered from a C-Series Display; it requires  
a split pedestal cable which combines the inter-unit and power cores.  
If you are connecting a C-series display to an existing open array scanner unit  
withastandardinter-unitcable, you can usetheadapatorcable insteadofthe  
split pedestalcable;connect the adaptorbetween the inter-unitcable and the  
display.  
These cables are illustrated in the following diagram. Cable lengths and part

Running the cable to the scanner  
CAUTION:  
Do not pull the cable through bulkheads using a cord attached to  
the connector. This could damage the connections.  
The cable entrance is at the rear of the scanner unit. If the unit is mounted on a  
hollow mast the cable may be run inside the mast and then fed through the  
radar’s cable entrance. Make sure that the cable does not chafe where it enters  
and exits the mast.  
Note: Route the cable from the display up to the scanner, since this will require  
the smallest clearance hole.  
Rejoining cables  
You should avoid cutting and re-joining cables. If this is necessary you must:  
Fit a ferrite on each side of the join. The specific ferrite to use depends on the  
cable type - contact Raymarine for details.  
Take care not to damage any of the wires. Make sure that all the wires and, in  
particular, the screen are reconnected correctly.  
If you are mounting the scanner on the mast of a sailboat, and will need to unstep  
the mast, you should install a suitable junction box inside the boat.  
Onanopenarrayscanner, thejunctionboxshouldprovidea13-wayterminalstrip  
with a 20 A rating for power cores. It is essential that all 4 power cores are  
connected and that the connection is of very low resistance as considerable  
power passes through this connection. Also, you should keep the length of the un-  
screened coaxial cores to less than 30 mm to maintain EMC conformance.  
CAUTION:  
The display connector on the scanner cable is a moulded plug that  
cannot be replaced. DO NOT remove this moulded plug.  
The minimum bends permitted are:  
Minimum bend, light cable  
Minimum bend, heavy cable  
60 mm (~2.5 in) radius  
82 mm (~3.75 in) radius  
 
cxcvii  
Open array scanner cables for Pathfinder displays  
Inter-unit cable  
The Pathfinder display inter-unit cables have a connector plug at one end for  
connecting to the display unit or extension cable; the other end is prepared ready  
to fit to the power and signal connectors (see Section 2.2).  
Heavy duty cables are available in 15 m and 25 m lengths which should be  
sufficient to complete the cable run required on most small vessels. For longer  
runs, 5 m and 10 m extension cables are available, both have 4 power cores to  
minimize voltage drops over the cable run and incorporate in-line moulded plugs.  
The maximum inter-unit cable length is limited by the minimum supply voltage  
and the scanner type.  
CAUTION:  
10 kW scanner systems cannot be used directly with 12 V systems;  
they require a 12 V to 24 V converter rated to 180 W. Contact your  
authorized Raymarine dealer or distributor for details.  
12 V Systems (4 kW scanners only)  
For vessels with 12 V power systems, the recommended cable(s) for different run  
lengths are given in the following table, which assumes a minimum supply  
voltage of 10.7 V (the lowest voltage likely to be reached by a 12 V battery in  
normal marine use). Do not use cable combinations that are not  
included in the table.

cxcviii  
24 V and 32 V Systems - 10kW scanners  
10 kW open array scanners can use any combination of inter-unit cable up to a  
maximum length of 35 m. However, these systems use considerable power and  
installations should be planned to minimize all cable lengths. Refer to the tables  
on page 1-19, Max. Extension Power Cable Lengths (m) - 10 kW Scanner.

The open array scanner systems are intended for use on ships’ DC power systems  
operating in the following ranges:  
4 kW  
10 kW  
10.7 to 44 V DC range (that is, 12 V, 24 V and 32 V systems)

10 kW open array scanner systems cannot be used directly with  
12 V systems; they require a 12 V to 24 V converter rated to 180 W.  
Contact your authorized Raymarine dealer or distributor for  
details.  
Open array scanners draw considerable power from the vessels power source,  
especially in high wind speeds. It is essential for reliable operation that the unit is  
supplied with a low resistance power cable system, especially when operated  
from a 12 V power system.  
12 V systems (4 kW scanners only)  
Extensionstothesuppliedpowercablemustbekepttoaminimumandthepower  
should be fed directly from the output of the battery isolator switch via its own  
dedicated cable system. It is recommended that no additional power switch is  
included in this power cable.  
CAUTION:  
The display unit does not include a fuse for scanner power, so an  
in-line fuse or circuit breaker MUST be included in the power  
cable.  
All power connections must be of high quality to minimize their resistance and to  
remove the risk of accidental shorts. Recommended maximum power cable  
extensions are given in the table below. These figures relate to the total cable  
extension, from the end of the supplied 1.5 m power cable to the system battery  
terminals. Do not exceed these lengths as unreliable operation may result.

Open array scanner cables for C-series displays  
A split pedestal cable is required to connect a compatible open array scanner to  
the display unit and to the power source.  
If you are connecting an existing compatible scanner to a C-Series display a  
pedestal adaptor cable can be used instead of the split pedestal cable.  
CAUTION:  
Do not extend the split pedestal or pedestal adaptor cable.  
Split pedestal cable  
The split pedestal cable combines the inter-unit and power cores, divided by a  
Y junction. One core has a connector plug for connecting to the display unit, the  
other core is for connecting to power. The scanner end is prepared ready to fit to  
the power and signal connectors (see Section 2.2).  
Two cable lengths are available:  
25m cableprovides 25m from scanner to Y junction.  
15m cableprovides 15m from scanner to Y junction.  
These lengths should be sufficient to complete the cable run required on most  
small vessels.  
Pedestal adaptor cable  
The pedestal adaptor cable combines the inter-unit and power cores, divided by a  
Y junction. One core has a connector plug for connecting to the display unit, the  
other core is for connecting to power. The scanner end has a connector plug for  
fitting to an existing inter-unit cable.  
2.5 Power Requirements  
Note: Open array scanners connected to a Pathfinder display and all radome scanners re-  
ceive power from the display unit via the inter-unit cable. The display power cable is sup-  
plied with the display unit and details for connecting power are provided in your display  
unitOwner’sHandbook. However,youshouldbeawareoftheinformationprovidedinthis  
section.  
The DC system should be either:  
Negative grounded, with the negative battery terminal connected to the  
ship’s ground.  
Floating, with neither battery terminal connected to the ship’s ground.  
 
ccii  
CAUTION:  
This radar is not intended for use on “positive” ground vessels.  
The power cable Earth screen connections must be connected to  
the ship’s ground.  
Grounding the radar system  
It is important that an effective RF ground is connected to the radar system.  
You must ground the radar by connecting the drain wire (screen) of the power  
cable to the nearest ground point of the ship’s RF ground system. Refer to your  
display unit Owner’s Handbook for details.  
If you need to extend the wire, the extension wire should be an 8 mm braid or  
AWG 10 (6.0 mm2) multi-stranded cable.  
If your vessel does not have an RF system, connect the drain wire to the negative  
battery terminal.  
Note: Use only this ground connection.  
Power Connections  
The power connection to the radar should be made at either the output of the  
battery isolator switch, or at a DC power distribution panel. Raymarine  
recommends that power is fed directly to the radar via its own dedicated cable  
system and MUST be protected by a thermal circuit breaker or fuse, fitted close to  
the power connection. Refer to the table below for isolator switch, circuit breaker  
or fuse value ratings. Check all terminal connections are clean.  
CAUTION:  
If you do not have a thermal circuit breaker or fuse in your power  
circuit, e.g. fitted to the DC distribution panel, you MUST fit an in-  
line breaker or fuse to the positive (red) lead of the power cable.

Chapter 3: Installing the Scanner  
3.1 Open array scanner  
Installation of the open array scanner should only be undertaken by a competent  
installer. If you have any difficulty with the installation, please contact your local  
Raymarine dealer or distributor.  
The open array scanner is supplied in two sections; the pedestal unit and the  
antenna. The pedestal unit is secured from below the mounting platform. The  
open array is then secured to the pedestal. Full details for mounting the scanner  
are given below.  
CAUTION:  
The pedestal unit has a cap fitted over the open array mounting  
shaft to protectthe protuding co-axial pin. This cap mustbe leftin  
place until the open array is fitted.  
The pedestal base is fitted with a seal: DO NOT grease this seal.  
WARNING:  
The open array scanner weighs: 48" scanner - 30 kg (66.2 lb); 72"  
scanner - 33.4 kg (73.7 lb). For safety reasons it is recommended  
that the unit is not lifted by one person.  
The unit is fitted with lifting eyes (maximum SWL 40 kg) to  
facilitatetheuseofstandardliftingaccessories, e.g.rope, chainor  
strop. The safe working load (SWL) of the lifting accessories  
shouldbe 150kg. Suitableliftingequipmentcould includeacrane,  
hoist, or an appropriate rigid, overhead structure.  
Alternatively, the unit is suitable for a two person lift. Care must  
be taken to ensure that each person is standing on a stable  
surface, and that the pedestal is held carefully to ensure it cannot  
slip.  
The T-bar beneath the open array antenna can be used to aid  
lifting.  
You should never lift the scanner by holding onto the open array  
antenna.  
 
ccviii  
Securing the pedestal to the mounting platform  
1. Using the paper template supplied with the scanner mounting kit, mark the  
flat mounting surface with the holes and drill as indicated on the template.  
Refer to Section 1.2 when selecting the scanner unit site.  
2. Stick the four self-adhesive bitumen washers over the mounting holes.  
3. Ensure the lifting eyes are securely fitted to the top of the pedestal, and the  
yellow protective cap is in place.  
CAUTION:  
To prevent damage to the internal mounting bar, ensure the stud  
penetration is no more than 32 mm into the pedestal base. We  
recommendyoumarkeachstudwithtape,32mmfromoneend, to  
act as a gauge.  
4. Greasethe studswith Densopaste(supplied). Using two nutslocked together  
on the stud, screw each stud into the pedestal to a maximum of 32 mm, or  
until they bottom out. Remove these two nuts.  
Note: If the studding supplied is not long enough, use M10 stainless steel, grade A4-70  
studding of a suitable length. Refer to the following illustration for details.  
5. Using suitable lifting equipment, raise the pedestal over the mounting sur-  
face. Carefullylowerintoposition, takingcarethat the studs pass throughthe  
holes without damaging the threads. Ensure that the cable inlet is pointing  
aft.  
WARNING:  
Support the pedestal unit until it has been secured to the

Chapter 4: Post Installation Checks and  
Maintenance  
Once you have installed your radar scanner and display unit, and made all the  
connections, you need to check your installation. You can then set up the radar  
system, alignthescannerandcheckthe displaytiming. Inaddition, fora72"open  
array scanner you need to set the antenna size to ensure the scanner rests in the  
correct position when rotation stops.  
Set up, alignment and timing checks are performed from the radar systemdisplay  
unit. The procedures are outlined below; full details are provided in the display  
unit Owner’s Handbook. You should read the Pathfinder radar display unit  
Owner’s Handbook and familiarize yourself with the operation of the radar.  
EMC Conformance  
Always check the installation before going to sea to make sure that it is not  
affected by radio transmissions, engine starting etc.  
4.1 System Checks and Alignment  
System check  
Before performing the functional test, check the following:  
Allsecuringboltsarefullytightenedandmechanicallockingarrangementsas  
specified are in place  
All connections have been made  
All connecting wires are secured and protected as necessary  
Note: If you are the boat owner and have performed the installation yourself, ask your au-  
thorized installation dealer to check the installation before going to sea.  
Set up, alignment and timing checks  
Switch on and initial set up  
On the open array scanner, ensure the power switch on the pedestal is set to ON.  
To switch on the display unit, press and hold the POWER key until the unit beeps.  
The magnetronwarm-up sequence should start, after whichthe unit should enter  
Standby mode.  
If necessary, adjust the lighting and contrast.  
If required, change the default language settings.  
 
ccxxiv  
Checking transmission  
WARNING:  
The radar scanner transmits electromagnetic energy. Ensure that  
thescanner has been installed according to the recommendations  
given in Chapter 1, and that all personnel are clear of the scanner,  
before switching to transmit mode.  
RunthroughtheradaroperationsdescribedinthedisplayunitOwner’sHandbook  
and check that all the expected data is displayed.  
Bearing alignment  
When the system is correctly installed, you must check the bearing alignment to  
ensure that targets appear at their correct bearing relative to the ship’s bow, and  
adjust the alignment if necessary.  
Display timing adjustment  
The display timing can be affected by the length of the cable used to connect the  
scanner to the display unit. This in turn affects the short range accuracy shown on  
the display.  
It is advisable to check the display timing before using the system for navigation.  
72" open array position alignment  
To ensure the 72" open array scanner rests in correct position when rotation  
stops, you need to adjust the radar set up as follows:  
1. With the display switched on in Radar mode, press MENU then press the  
RADAR SET UP soft key.  
2. Use the cursor to select the ANTENNA SIZE option, then press the 6 ft soft key.  
Press ENTER twice to return to the default display.  
If the Radar Set Up menu option ANTENNA SIZE is not available, then you  
have an older version of display software. The 72" open array scanner will  
operate correctly with this display. However, for details on adjusting the open  
array stopping-position, please contact your authorized Raymarine dealer or  
distributor.  
 
ccxxv  
4.2 Maintenance  
Warnings  
The display unit and scanner unit contain high voltage.  
Adjustments require specialized service procedures and tools  
only available to qualified service technicians - there are no user  
serviceable parts or adjustments and the operator should not  
attempt to service the equipment. The operator should not  
remove the rear cover of the display or any internal covers in the  
scanner.  
Always turn the radar system off before carrying out any routine  
maintenance on the scanner or nearby equipment. Switch off the  
display unit before removing the power cord.  
Routine Checks  
The radar scanners are sealed units. Maintenance procedures are therefore  
limited to the following periodical checks:  
Examine the cables for signs of damage, such as chafing, cuts or nicks.  
Check that the cable connectors are firmly attached.  
Make sure the scanner and pedestal are still attached securely to the mount-  
ing.  
Once a year, remove, grease and re-attach the mounting bolts securing the  
scanner and pedestal.  
Servicing and Safety  
Raymarine equipment should be serviced only by authorized Raymarine ser-  
vice technicians. They will ensure that service procedures and replacement  
parts used will not affect performance. There are no user serviceable parts in  
any Raymarine product.  
Some products generate high voltages, so never handle the cables/connec-  
tors when power is being supplied to the equipment.  
When powered, all electrical equipment produces electromagnetic fields.  
These can cause adjacent pieces of electrical equipment to interact with one  
another, with a consequent adverse effect on operation. In order to minimize  
these effects and enable you to get the best possible performance from your  
Raymarine equipment, guidelines are given in the installation instructions, to  
 
ccxxvi  
enable you to ensure minimum interaction between different items of equip-  
ment, i.e. ensure optimum Electromagnetic Compatibility (EMC).  
Always report any EMC-related problem to your nearest Raymarine dealer.  
We use such information to improve our quality standards.  
In some installations, it may not be possible to prevent the equipment from  
being affected by external influences. In general this will not damage the  
equipment but it can lead to spurious resetting action, or momentarily may  
result in faulty operation.  
4.3 Problem Solving  
All Raymarine products are subjected to comprehensive test and quality  
assuranceprogrammespriortopackingandshipping.However,ifthisunitshould
