Receiving/Transmitting
After you have turned your radio on and selected the desired zone and
channel, you can receive (listen) 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
(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
.
