Important Safety Information
See the Important Safety and Product Information guide in the product box for product warnings and other
important information.
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
To avoid possible personal injury or damage to the device and vessel, disconnect the vessel's power supply
before beginning to install the device.
To avoid possible personal injury or damage to this device and vessel, only install this device when the vessel is
on land, or when properly secured and docked in calm water conditions.
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
FCC Compliance
In the USA, it is prohibited under FCC regulations to enter incorrect or improper data, and it is prohibited for any
person other than the manufacturer or the installing dealer to input an MMSI number.
It is a violation of the rules of the FCC to input an MMSI number that has not been properly assigned to the user,
or to otherwise input any inaccurate data in this device.
Assigning Data to the Device
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.
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)
