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.
• You must mount the device in a location where it will not be
submerged.
• You must mount the device in a location with adequate
ventilation where it will not be exposed to extreme
temperatures.
For optimal internal GPS reception:
• You should mount the device in a location where it is above
the water line when the ship is in the water.
• You should mount the device as far as possible, at least
20 cm (7.9 in.), from cables, electronics, metal objects, and
other potential sources of GPS interference.
• If you mount the device in a boat with a metal hull, you must
connect the device to an external GPS antenna (sold
separately).
• If possible, you should mount the device horizontally, with the
face of the device pointing upward or vertically with the LEDs
facing upward. The GPS is most sensitive in these positions.
VHF Antenna Mounting and EME Exposure
WARNING
Radio operators with cardiac pacemakers, life-support
machines, or electrical medical equipment should not be
exposed to excessive radio-frequency (RF) fields, because the
RF field may interfere with the function of their medical
equipment.
CAUTION
This device generates and radiates radio frequency (RF)
electromagnetic energy (EME). Failure to observe these
guidelines may expose people to RF radiation absorption
exceeding the maximum permissible exposure (MPE).
Garmin
®
declares an MPE radius of 2.48 m (97.64 in.) for this
system, which was determined using 5 W output to an omni-
directional, 6 dBi gain antenna. The antenna should be installed
to maintain a distance of 2.48 m (97.64 in.) between the antenna
and all people.
Mounting the Device
NOTICE
If you are mounting the device in fiberglass, when drilling the
pilot holes, use a countersink bit to drill a clearance counterbore
through only the top gel-coat layer. This will help to avoid
cracking in the gel-coat layer when the screws are tightened.
Before you mount the device, you must select a mounting
location and determine the mounting hardware needed for the
surface.
NOTE:
Mounting hardware is included with the device, but it
may not be suitable for the mounting surface.
1
Place the device in the mounting location and mark the
location of the pilot holes.
2
Using a bit appropriate for the surface and the mounting
hardware, drill a pilot hole for one corner of the device.
3
Loosely fasten the device to the surface with one corner and
examine the other three pilot-hole marks.
4
Mark new pilot-hole locations if necessary.
5
Remove the device from the mounting surface.
6
Drill the appropriate pilot holes for the other three marks.
7
Secure the device to the mounting location.

Connecting the Device to Power
WARNING
When programmed with a valid MMSI number, this device
allows you to transmit AIS signals with vessel position data. This
device is meant to enhance situational awareness and may not
prevent vessel collisions in all circumstances. It is your
obligation to be aware of your surroundings and to ensure safe
operation of the vessel.
CAUTION
After installing the device and programming a valid vessel MMSI
number, you can temporarily revert to the default silent mode
(only receives, does not transmit) using a toggle switch (not
included) (
Connecting the Device to Power
). While
operating in silent mode, the device does not transmit AIS
signals.
Four wires (red, black, green, and yellow) provide the basic
power connection.
1
Route the wiring harness from the device POWER (and
NMEA 0183) port to the battery .
2
Connect the red wire to the positive (+) battery terminal.
3
Connect the black wire to the power ground on the
negative (-) battery terminal.
4
Connect the green wire to the power ground with a switch
(not included) between the green wire and power ground, to
provide a toggle , switch to revert to the default silent
mode (optional).
