Transmit timer
Your radio may have a transmit timer that limits the amount 
of time you can transmit continuously. When the transmit 
timer is about to expire, the red LED flashes and the radio 
gives three beeps. You must release the PTT before you can 
transmit again.
Note: Your radio may be unable to transmit for a short 
time after the transmit timer has expired.
Receiving a call
When there is valid activity on your radio’s currently 
selected channel or group, the radio then unmutes and you 
can hear the call.
If the incoming call contains special signalling that matches 
the signalling programmed for your radio, the green LED 
flashes and your radio may give a ringing tone.
