Standby and Receive
Standby mode is the usual mode for the radio whenever it is turned On. From this
mode, you can change your settings using the buttons on the front of the radio
and switch to Transmit mode using the Talk button. Signals will be Received on
the selected channel(s) and alerts broadcast by the coastguard will activate the
corresponding routines in your radio.
NOTE
Coastguard alerts are broadcast on Channel 16.
While in Standby mode, you will receive any messages sent on the
channel to which you are tuned.
Transmit
Transmit mode gives you the ability to interact with
safety services, other vessels and shore stations. When
you use this capability, be sure to follow the procedures
and to observe the courtesies that govern its use so
everyone benefits. (See pages 12 – 21 to help you
select the proper channels.)
To transmit a message:
1. Check to see that your radio is set to a proper
channel for the type of message you plan to send.
2. Toggle to the low power setting.
3. With the microphone about 5 cm from your mouth, press
and hold the Talk button and speak into the microphone.
The Transmit icon and meter will appear on the LCD.
4. Release the Talk button when you have finished
speaking. Your radio can only operate in either the
Transmit or the Receive mode at any given time.
You will not hear the response to your message
unless the
Talk button is released.
If the
Battery Power icon begins blinking on the
LCD when the Talk button is depressed, the radio
will NOT transmit and the Transmit icon will blink.
If the
Talk button is held down for five minutes,
the radio will automatically cease transmitting to
prevent unwanted signal generation and battery
drain. As soon as the Talk button is released,
it can be pressed again to resume transmission.
