Making a call

1

Select the required channel or scan group.

You may need to select the zone you want first, then select 

the channel or group from that zone.

2

Check that the channel is clear. If the green LED is glow-

ing, the channel is busy and you may not be able to trans-

mit.

3

Once the channel is clear (the green LED is off), lift the 

microphone off the microphone clip.

4

Hold the microphone about 5cm (2 inches) from 

your mouth.

5

Press and hold the PTT key to transmit.

6

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.

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 has timed out, you must release the PTT 

before you can transmit again.

Your radio may be unable to transmit for a short time after 

the transmit timer has expired.
