•

After the called party answers, press the PTT switch to talk and 
release it to listen. You cannot talk and listen at the same time because 
the radio cannot transmit and receive at the same time. Each time the 
PTT switch is released, a tone is heard by the other party that indicates 
when a response can be made. To end the call when the conversation 
is complete or at any other time, press the CLR key.

service, “LOST CALL” is displayed and a continuous tone sounds. 
End the call by pressing the CLR key.

If the radio system is busy, “BUSY” is displayed and a busy tone

position in queue is lost.
