Overview<\/h2>\n\n\n\n

The Garmin VHF Radio System<\/strong> installed on Ocean Alexander yachts includes an integrated Hailer Function<\/strong> that allows the operator to use the vessel\u2019s VHF transceiver and connected hailer speaker for onboard communication and sound signaling.<\/p>\n\n\n\n

The hailer function is useful for communicating with crew on deck, assisting with docking operations, making announcements, and providing audible signals when maneuvering in areas with limited visibility.<\/p>\n\n\n\n

This article demonstrates how to operate the Garmin VHF Transceiver as a Hailer<\/strong> and provides a quick reference for accessing and using this feature through the vessel\u2019s Garmin electronics system.<\/p>\n\n\n\n

\n\n\n\n

Hailer Function Uses<\/h1>\n\n\n\n

The Garmin Hailer feature may be used for:<\/p>\n\n\n\n

    \n
  • Communicating with crew on deck.<\/li>\n\n\n\n
  • Docking and maneuvering assistance.<\/li>\n\n\n\n
  • Making general vessel announcements.<\/li>\n\n\n\n
  • Communicating with personnel near the vessel.<\/li>\n\n\n\n
  • Producing required sound signals where applicable.<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    Before Using the Hailer<\/h1>\n\n\n\n

    Before activating the hailer function:<\/p>\n\n\n\n

      \n
    • Confirm the Garmin VHF radio is powered on.<\/li>\n\n\n\n
    • Verify the hailer speaker is operational.<\/li>\n\n\n\n
    • Ensure the correct VHF station is selected.<\/li>\n\n\n\n
    • Confirm the vessel is operating safely.<\/li>\n\n\n\n
    • Adjust volume levels appropriately for the operating environment.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      Operating the Garmin Hailer<\/h1>\n\n\n\n

      To use the Garmin VHF as a hailer:<\/p>\n\n\n\n

        \n
      1. Access the Garmin VHF Radio Interface<\/strong>.<\/li>\n\n\n\n
      2. Select the Hailer<\/strong> function.<\/li>\n\n\n\n
      3. Confirm the hailer output is active.<\/li>\n\n\n\n
      4. Adjust the hailer volume as required.<\/li>\n\n\n\n
      5. Press and hold the communication control to speak.<\/li>\n\n\n\n
      6. Release the control to listen.<\/li>\n<\/ol>\n\n\n\n

        The hailer speaker will broadcast the operator\u2019s voice through the external hailer speaker installed on the vessel.<\/p>\n\n\n\n

        \n\n\n\n

        Returning to Normal VHF Operation<\/h1>\n\n\n\n

        After completing hailer use:<\/p>\n\n\n\n

          \n
        1. Exit the Hailer function.<\/li>\n\n\n\n
        2. Return the VHF radio to the desired communication channel.<\/li>\n\n\n\n
        3. Confirm normal radio operation.<\/li>\n\n\n\n
        4. Verify volume and squelch settings are appropriate.<\/li>\n<\/ol>\n\n\n\n
          \n\n\n\n

          Troubleshooting<\/h1>\n\n\n\n

          If the hailer function does not operate:<\/p>\n\n\n\n

          Verify:<\/p>\n\n\n\n

            \n
          • Garmin VHF radio has power.<\/li>\n\n\n\n
          • Hailer speaker connections are secure.<\/li>\n\n\n\n
          • Correct hailer output is selected.<\/li>\n\n\n\n
          • Volume level is adjusted properly.<\/li>\n\n\n\n
          • Network communication between Garmin devices is active.<\/li>\n\n\n\n
          • No active radio faults are present.<\/li>\n<\/ul>\n\n\n\n

            If communication remains unavailable, inspect the hailer speaker and associated wiring.<\/p>\n\n\n\n
