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.
  4. Connect the green wire on the data harness to the negative (-) wire from the hailer horn or PA speaker.
  5. Cover the connections with waterproof tape or heat-shrink tubing.
