Standby/Receive And Transmit

Standby And Receive

Standby 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 Coast Guard and NOAA will
activate the corresponding routines in your radio.

NOTE
Coast Guard alerts are broadcast on Channel 16 and you 
need to have weather alert turned 

On to receive NOAA alerts.

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 14 through 23 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 two (2) inches [five (5) cm] 

from your mouth, press and hold the Talk button 
and speak into the microphone. The Transmit icon 
will appear on the LCD.

4. Release the Talk button when you are 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 (5) 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.
