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.
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.
- Route or extend the wire from the hailer horn or PA speaker to the radio.
- Connect the white wire on the data cable to the positive (+) wire from the hailer horn or PA speaker.
- Connect the green wire on the data cable to the negative (-) wire from the hailer horn or PA speaker.
- Cover the connections with a waterproof tape or heat-shrink tubing.
