Basic Operation
Using the Intercom
The intercom is part of the Public Address (PA) system of your radio. You can use multiple
handset stations as an intercom system for two-way communication. Use the radio handset
to initiate communication with a remote handset station, and use a remote handset station to
initiate communication with the radio handset.
TIP: When the radio is in intercom mode, it does not receive trafc from your current
channel.

2. Select a device from the list. Selecting ALL will transmit to every station. The other party
must press the PTT key on the receiving unit to accept the call.
3. Press and hold the PTT key and speak your message.
4. Release the PTT key and listen for a response.
5. When you and the other party have nished talking, select EXIT to return to the Home
screen.
Receiving an Intercom Call
1. The screen indicates which station is calling. Press and release the PTT key to accept
the call.
2. When the other party has nished talking, press and hold the PTT key and speak your
message.

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 trafc from your current
channel.
