A DSC warning label is supplied with this LowranceVHF radio. To comply with FCC regulations,
this label must be affixed in a location that is clearly visible from the operating controls of this
radio. Make sure that the chosen location is clean and dry before applying this label.
This radio is designed to generate a digital maritime distress call to facilitate search and rescue.
To be effective as a safety device, this radio must be used only within the geographic range of
a shore-basedVHF marine Channel 70 distress and safety watch system. The geographic range
may vary but under normal conditions is approximately 20 nautical miles.
MMSI and license information:
You must obtain a user MMSI (Marine Mobile Service Identity) and enter it into your Link-8
in order to use the DSC functions. Contact the appropriate authorities in your country. If
you are unsure who to contact, consult your Lowrance dealer.
The user MMSI is a unique nine digit number, similar to a personal telephone number. It is
used on marine transceivers that are capable of using DSC (Digital Select Calling).
Depending upon your location, you may need a radio station license for the Link-8. You
may also need an individual operator’s license.
Lowrance recommends that you check the requirements of your national radio
communications authorities before operating DSC functions.

•
Is at least 3’(1 m) from the antenna
Allows easy connection to (at least) a 10 Amp fused 13.6 V DC electrical source and the
antenna
•
Is at least 1.5’ (45 cm) from the compass to avoid creating magnetic deviation of the
compass during radio operation
•
•
•
•
Has a suitable space close by for installing the microphone bulkhead mount
Provides easy access to the controls on the front panel
Provides reasonable access to the wiring at the back of the radio
Provides enough room to fix the DSC warning label.

2.3.1 Mounting bracket installation
1. Hold the supplied mounting bracket at the chosen location and use a soft pencil to
mark the 4 screw hole positions onto the mounting surface.
2. Drill the 4 screw holes where marked. Drill completely through the mounting surface.
Note: If you are drilling into fiberglass, use a small drill bit to drill pilot holes before drill-
ing the screw holes.
3. Use the flat screws, spring washers, plain washers, and nuts to attach the mounting
bracket to the location site OR, if you cannot reach behind the mounting surface to
attach the nuts, use the self-tapping screws instead of the flat screws.
4. Slide the radio into the mounting bracket.
5. Insert the 2 mounting knobs through the holes and tighten them sufficiently to hold
the radio at your preferred viewing angle.
6. You can adjust the viewing angle at any time. The viewing angle has a 20º tilt range.
7. Now install the microphone wall hanger.

2.3.2 Recessed installation
1. Tape the supplied mounting template to the chosen location. Ensure that the template
is smooth and taut.
2. Drill the 2 screw holes where marked. Drill completely through the mounting surface.
Note: If you are drilling into fiberglass, use a small drill bit to drill pilot holes before drill-
ing the screw holes.
3. Drill through the corners of the hatched area where marked, then cut out the hatched
area to create a cavity in the mounting surface. (The dashed line shows the total area
that will be covered by the radio fascia after installation).
4. Remove the mounting template and slide the radio into the cavity.
5. Working from the rear of the bulkhead, screw the radio firmly to the mounting surface
using the 2 M5 x 32 screws with the plain washers and nuts.
(The screws should not be visible from the front of the radio).
