FEATURES  
Electronic iris function  
Terminology explanation  
The electronic iris function regulates the  
electronic shutter speed. To the contrary of  
electronic shutters with a fixed speed, the  
electronic iris modifies the shutter speed  
according to the CCD input. The electronic  
iris will automatically control the amount of  
light entering the camera, so manual iris  
lenses can be used on the camera.  
About the DC type lenses  
These lenses use a DC power supply  
without amplifier circuits. They are also  
referred to as non internal amplifier type  
lens or coil type lens.  
About the VIDEO type lenses  
These lenses use both a video signal  
amplified by internal amplifier circuits and a  
DC power supply. They are referred to as  
internal amplifier type lens.  
Backlight compensation function  
The backlight compensation function will  
divide the screen in two areas (A) and (B),  
as illustrated below. Then, the iris is  
automatically set so the outside zone (B)  
brightness is given less weight than the  
brightness from the center zone (A), giving  
the best possible image.  
1/3 inch solid state image device CCD  
CS type lens mount  
C mount lenses can also be used with the  
supplied C mount adaptor.  
High speed electronic shutter  
8 speeds, selectable by switches.

PRECAUTIONS  
In case of problem  
Do not install close to stoves, or other heat  
generating devices, such as spotlights, etc.,  
or where it could be subject to direct  
sunlight, as that could cause deformation,  
discoloration or other damages.  
Be careful when installing close to the  
ceiling, in a kitchen or boiler room, as the  
temperature may raise to high levels.  
Do not use the camera if smoke or a  
strange odor comes from the unit, or if it  
seems not to function correctly. Disconnect  
the power cord immediately, and consult  
your dealer (or a Sanyo Authorized Service  
Center).  
Do not open or modify  
Install where the temperature range will  
stay between –10˚C and 50˚C.  
(no condensation)  
Do not open the cabinet, as it may be  
dangerous and cause damage to the unit.  
For internal settings and repairs, consult  
your dealer (or a Sanyo Authorized Service  
Center).  
Cleaning  
Dirt can be removed from the cabinet  
by wiping it with a soft cloth. To  
remove stains, wipe with a soft cloth  
moistened with a soft detergent  
solution and wrung dry, then wipe dry  
with dry soft cloth.  
Do not put objects inside the unit  
Make sure that no metal objects or  
flammable substance get inside the camera.  
If used with a foreign object inside, it could  
cause a fire, short-circuits or damages.  
Do not use benzine, thinner or other  
chemical product on the cabinet, as that  
may cause deformation and paint  
peeling. Before using a chemical cloth,  
make sure to read all accompanying  
instructions. Make sure that no plastic  
or rubber material comes in contact  
with the cabinet for a long period of  
time, as that may cause damage or  
paint peeling.  
If water or a liquid gets inside the camera,  
disconnect the power cord immediately,  
and consult your dealer (or a Sanyo  
Authorized Service Center). Be careful to  
protect the camera from rain, sea water,  
etc.  
Be careful when handling the unit  
To prevent damages, do not drop the  
camera or subject it to strong shock or  
vibration.  
Install away from electric or  
magnetic fields  
If installed close to a TV, radio transmitter,  
magnet, electric motor, transformer, audio  
speakers the magnetic field they generate  
will distort the image.  
Protect from humidity and dust  
To prevent damages to the camera, do not  
install it where there is greasy smoke or  
steam, where the dampness may get too  
high, or where there is a lot of dust.  
Protect from high temperatures

Camera installation  
A: Lens mount cap  
Remove the lens mount cap before  
installing the lens (sold separately).  
Use with this camera a CS mount type  
auto-iris lens (for 1/3 inch).  
Auto-iris lenses regulate the amount of  
light entering the camera according to  
the brightness of the subject.

C mount auto-iris lenses can also be used  
with the supplied adaptor (see page7).  
CAUTION:  
When installing the camera support,  
select a location that can support the  
total weight of the camera and  
accessories.  
This installation should be made by  
a qualified service person and  
B: Installation bracket  
The bracket can be fitted at the top or  
bottom of the camera. To fix the  
bracket, make sure to use the screws  
that held the bracket before, and use  
the other two screws to seal the

3 Connect the lens plug to the LENS  
connector on the side of the camera.  
When using lenses from other makers,  
make sure that the pins connections in the  
plug correspond to the ones of the camera.  
Refer to the lens specifications to check the  
pins connections in the plug. If they are  
different from the ones indicated in the  
diagram, remove the original plug and  
connect the supplied plug according to the  
connections indicated by the diagram.

TROUBLESHOOTING  
Before taking the camera for repairs, please check below to make sure that the camera is  
used correctly. If it still does not perform correctly, please consult your dealer or a Sanyo  
Authorized Service Center.  
No picture on the monitor screen  
Is the power turned on to all connected devices? Is the voltage correct?  
Are all the signal connecting cables correctly connected?  
Is the lighting sufficient?  
Has the lens cap been removed?  
Is the lens type (DC or VIDEO) correctly selected?  
Depending on the type of lens, the A. I. LENS switch must be set accordingly.  
Is the iris control correctly set?  
A: When using a DC type lens, the LEVEL volume (inside the camera casing) should be  
adjusted.  
B: When using a VIDEO type lens, the LEVEL volume (on the lens) should be adjusted.  
The picture is not clear  
Is the monitor correctly adjusted?  
Is the flange-back position correctly set?  
Is the lens focus correctly adjusted?  
Are the lens surfaces clean?  
If there is dust or finger prints on the lens, the image quality will deteriorate. To clean the  
lens use a soft cloth or a commercially available lens cleaning set.  
SERVICE  
This camera is a precision instruments and if treated with care, will provide years of  
satisfactory performance. However, in the event of a problem, the owner is advised not to
