General Radio Operation
 
Receiving/Transmitting
 
After you have turned your radio on and selected the desired zone and 
channel, you can receive (listen to) or transmit (send) communications as 
follows:
1a. Listen until 
you hear a 
transmission.
2. Adjust the 
 
Volume Control Knob
 
 for a 
comfortable listening level.
3. To transmit, press and hold the 
PTT Switch and speak clearly into 
the microphone. The LED will 
continuously light red while the 
radio is transmitting. When you 
have finished talking 
(transmitting), release the PTT 
Switch to listen (receive).
• If the channel on which you are transmitting is 
programmed to receive Private-Line® (PL), ensure that 
the channel is not in use by momentarily pressing the 
Monitor Button (if programmed, see page 2) to listen for 
activity. To put the radio in permanent monitor 
operation (squelch defeat), press and hold the Monitor 
Button for five seconds (time programmable through 
radio service software). To return the radio to its original squelch state, tap 
the Monitor Button again or press the PTT Switch.
• If you try to transmit on a channel that is programmed for receive only, 
an invalid tone will sound until you release the PTT Switch.
