■
On-air call setup: The radio gives a ring and automatically
accepts the call. The
symbol appears in the display.
■
Full off-air call setup (FOACSU): When a call is received, the
radio rings like a telephone.
To accept the call, press Answer . The radio gives a beep and
the symbol appears in the display. You may also be able
to accept the call if you briefly press the PTT key or lift the
microphone off the microphone clip.
Once the symbol appears, 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 and the transmit symbol
appears in the display.
4 End the call by placing your microphone back onto its hook
or by pressing
Clear . The network may also end the call if
neither you nor the other party transmits for a predeter-
mined time or if you 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 message
Transmit timeout imminent
appears in the display, the red LED flashes
and the radio gives three beeps.
If the transmit timer times out, the call clears down.
Call time limit
In MPT trunked mode, the length of your call may be limited
by the network or by your radio. Your radio may be
programmed to display the time remaining for your call.
