Connecting the Device to a Remote GPS Antenna
This device must receive GPS information for proper functionality. You can connect the device to a NMEA 2000
network with a GPS antenna, or you can install a remote GPS antenna (not included) and connect it to the
device.
1 Follow the instructions provided with your external GPS antenna to install it on your boat correctly.
2 Route the antenna cable to the back of your device, away from sources of electrical interference.
3 Connect the antenna cable to the GPS port on your device.
Connecting to a Hailer Horn or PA Speaker
You can connect the VHF radio to a hailer horn or public address (PA) speaker (not included) to use a handset
to make announcements.
Some VHF models include a foghorn feature as part of the public address system. You can sound the foghorn
through a hailer horn or PA speaker. To use the foghorn feature you must provide and install a hailer horn
(optional) on the deck or tower of your boat.
1 If necessary, mount the hailer horn or PA speaker according to the installation instructions provided with the
hailer horn or PA speaker.
NOTE: To avoid feedback, you should mount the hailer horn or PA speaker at least 3 m (10 ft.) away from,
and facing away from, a handset.
2 Route or extend the wire from the hailer horn or PA speaker to the radio.
3 Connect the white wire on the data harness to the positive (+) wire from the hailer horn or PA speaker.
