Using the Hailer You must provide and install an optional hailer horn on the deck or tower to use the hailer feature. See the VHF 300 Series Installation Instructions for installation information. The hailer, which is part of the PA system of your radio, allows you to make on-boat or ship-to-shore announcements. The hailer allows two-way communication; you can address the ship using the handset, and sounds received through the horn can be heard through the external speaker. For vessels with enclosed cabins, this allows you to hear what is happening on deck. NOTE: When the radio is in hailer mode, it does not receive traffic from your current channel.
