Assigning Data to the Device

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

You must program the Garmin AIS™ 800 device with a valid vessel MMSI number before installing the device on your boat. By default, the device operates in silent mode until you program the device with a valid vessel MMSI number. In silent mode, the device receives, but does not transmit, AIS signals with position data. You can program the device to transmit static vessel data including the vessel name, call sign, type, and dimensions, including the location of the vessel's GPS antenna.

You can program the device to transmit vessel position data and static vessel data including the vessel name, call sign, type, dimensions, and the location of the vessel's GPS antenna. It is also possible to temporarily revert to silent mode (only receives, but does not transmit, vessel data) by means of a toggle switch (not included) (Connecting the Device to Power).
