Voice Transmission
•
Use the Transmit (TX) mode to communicate with safety
services, other vessels and shore stations. When using this
capability, follow appropriate procedures and observe the
expected courtesies.
Before pressing the Talk button to transmit a message, select
the appropriate channel and transmit power output.
Channels
Voice messages may be transmitted on most VHF channels.
Refer to the VHF marine channel assignments on pages 14-23
to select a channel based on the type of message being
transmitted.
Choose One of the Following Options to Change the
Channel:
■ Turn the Channel knob or press the microphone Channel
Up/Down buttons. This moves the channel to the next
higher or lower VHF channel. (When on Channel 88A, the
next higher channel is Channel 1 and vice versa.) For
rapid advance, press and hold the microphone Channel
Up/Down buttons. (The confirmation key tone sounds for
each button press, but not during rapid advance.)
■ Press the Channel 16/9 button on the radio or the
microphone. This selects Channel 16 with one press and
Channel 9 with a second press. Additional presses will
toggle between Channel 16 and Channel 9. Press and
hold the Channel 16/9 button to return to Standby mode.
NOTE
The radio will automatically select high power on
channel 16 if you use the Channel 16/9 button to
select this channel. Select 16 manually or save it as
a preset if you would like to routinely use channel
16 on low power mode.
