Receiving a call
When you receive a call, your radio may display the caller’s
number and respond in one of two ways, depending on the
way it was programmed and the way your network operates.
■ On-air call setup: The radio gives a ring and automatically
accepts the call. The green LED glows to show that the
system has assigned a traffic channel.
■ Full off-air call setup (FOACSU): When a call is received,
the radio rings like a telephone.
To accept the call, briefly press the PTT key or lift the
microphone off the microphone clip. The green LED glows
to show that the system has assigned a traffic channel.
Once the green LED glows, you can proceed with the call,
as follows:
1 Hold the microphone about 5cm (2 inches) from
your mouth.
2 Press and hold the PTT key to transmit.
3 Speak clearly into the microphone and release the PTT
key when you have finished talking.
While you are transmitting, the red LED glows.
4 End the call by placing your microphone back onto its
hook or by pressing the clear key . The network may
also end the call if neither you nor the other party
transmits for a predetermined time or if your call time
limit is exceeded.
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.
If the transmit timer times out, the call clears down.
