Mounting Considerations
NOTICE
This device should be mounted in a location that is not exposed to extreme temperatures or conditions. The
temperature range for this device is listed in the product specifications (Specifications, page 4). Extended
exposure to temperatures exceeding the specified temperature range, in storage or operating conditions, may
cause device failure. Extreme-temperature-induced damage and related consequences are not covered by the
warranty.
• To avoid interference with a magnetic compass, do not install the handset closer than 70 cm (27.5 in.) to a
compass.
• You can use the included 10 m (32 ft.) extension cable to connect the handset to the VHF radio. You must
select a mounting location for the handset where you can connect the extension cable to the handset and to
the VHF radio. If needed, up to two additional 10 m (32 ft.) extension cables can be connected in series with
the first extension cable. The maximum allowable total extension cable length between any handset and the
VHF radio is 30 m (96 ft.). Extension cables are available from your Garmin® dealer or website.
• You can use the included screws to mount the handset connector and the handset cradle mount on your
boat. If the included screws are not appropriate for the mounting surface, you must purchase suitable
hardware.

Installing the Extension Cable in the Mounting Surface
Before drilling a hole to mount the extension cable, you must make sure that the extension cable is long enough
to connect to the microphone relocation port or a STATION port on the VHF radio from the selected mounting
location (Mounting Considerations, page 2).
1Using the mounting plate as a template, trace the cable hole in the center of the mounting plate and mark
the screw locations.
2Set the mounting plate aside.
Do not drill through the mounting plate.
3Using a 22 mm (7/8 in.) drill bit or hole saw, drill the center cable hole in the mounting surface.
4Using a 3 mm (1/8 in.) drill bit, drill the pilot holes.
5Apply marine sealant between the mounting plate and the mounting surface to help seal the holes (optional).
6Using the included screws, attach the mounting plate to the mounting surface.
7Connect one end of the extension cable to the microphone relocation port or a STATION port on the VHF
radio, and route the other end of the extension cable to the mounting location.
8Feed the extension cable connector through the back of the mounting surface.
9Apply marine sealant around the extension cable connector in the mounting plate to help seal the hole
(optional).
10 Secure the extension cable connector to the mounting plate using the weather cap and the nut .
11 Connect the handset to the extension cable.
Installing the Handset Cradle
You should install the handset connector in the mounting surface before installing the handset cradle (Installing
the Extension Cable in the Mounting Surface, page 3).
1Select a mounting location for the handset cradle near the handset connector.
TIP: To help determine the best location, you can place the handset in the cradle, connect the handset to the
connector, and hold it against the mounting surface.
2Using the cradle as a template, mark the screw locations.
3Set the cradle aside.
Do not drill through the cradle.
4Using a 3 mm (1/8 in.) drill bit, drill the pilot holes.
5Using the included M3.5 screws, secure the cradle to the mounting surface.
