Connecting to an External Speaker
You can connect your VHF device to an external marine speaker (not included) to amplify sound at remote
locations on the vessel or to communicate with other vessels.
1 If necessary, mount the external marine speaker according to the installation instructions provided with the
speaker.
2 Route or extend the wire from the external speaker to the VHF device.
3 Connect the red wire on the data cable to the positive (+) wire from the external speaker.
NOTE: Make sure this is the red wire on the data cable. The power harness has a red wire that connects to
the power source.
4 Connect the black wire on the data cable to the negative (-) wire from the external speaker.
NOTE: Make sure this is the black wire on the data cable. The power harness has a black wire that connects
to the power ground.
5 Cover the connections with a waterproof tape or heat-shrink tubing.
Connecting to a Hailer Horn or PA Speaker
You can connect a VHF 215 radio to a hailer horn or public address (PA) speaker (not included) to use the
microphone or the handset to make announcements.
NOTE: The VHF 115 models cannot be connected to a hailer horn.
Some VHF models include a foghorn feature as part of the public address system. You can sound the foghorn
through a hailer horn or a PA speaker. To use the foghorn 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
device.
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, the microphone or 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 cable to the positive (+) wire from the hailer horn or PA speaker.
4 Connect the green wire on the data cable to the negative (-) wire from the hailer horn or PA speaker.
5 Cover the connections with a waterproof tape or heat-shrink tubing.
