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. 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.

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 omnidirectional, 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.

Place the device in the mounting location and mark the location of the pilot holes.
Using a bit appropriate for the surface and the mounting hardware, drill a pilot hole for one corner of the device.
Loosely fasten the device to the surface with one corner and examine the other three pilot-hole marks.
Mark new pilot-hole locations if necessary.
Remove the device from the mounting surface.
Drill the appropriate pilot holes for the other three marks.
Secure the device to the mounting location.

Connection Considerations

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, page 2). While operating in silent mode, the device does not transmit AIS signals.

Four wires (red, black, green, and yellow) provide the basic power connection.

Route the wiring harness from the device POWER (and NMEA 0183) port to the battery .
Connect the red wire to the positive (+) battery terminal.
Connect the black wire to the power ground on the negative (-) battery terminal.
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).
Complete an action, based on the network type:
- In a NMEA 0183 system, connect the yellow wire (Accessory On) to the power ground, and install a switch (not included) between the yellow wire and the power ground.
  NOTICE
  Turning off the switch prevents the device from draining the battery when the engine is off.
- In a NMEA 2000 system, the device automatically powers on and off with the system, and you do not need to connect the yellow Accessory On wire.

Connecting a VHF Antenna

To transmit and receive AIS information, the AIS 800 must be connected to external VHF antenna (not included). The device has an internal antenna splitter that allows VHF and AIS to share a single antenna.

Mount the VHF antenna (sold separately) according to the installation instructions provided with the antenna.
NOTE : You can purchase a VHF antenna extension cable. Go to buy.garmin.com or contact your Garmin dealer.
Connect the VHF antenna cable to the VHF ANT port on the Garmin AIS 800 device.

NMEA 2000 Device Connections
