Channel Selection

4-Channel Model

128-Channel Model

To select a channel, enter channel mode

( displayed) by pressing channel select button (9c), then use the up/down scroll buttons (7) to display the desired channel number. The channel may be used as soon as it is displayed.

Channel Without Selective Call Functions

When you have selected a channel, you are ready to transmit. You should only make a call when the channel is free ( red indicator (4) does not flash). If in doubt, press the monitor button (5) to listen to the channel.

Communication Procedures

Take the microphone out of its holder. Press the transmit (PTT) key (11) on the side of the microphone while talking, release it while listening. Speak in a normal tone of voice, keeping a distance of 5-10 cm from the microphone. When transmitting the red indicator (4) will light continuously. Your radio may be configured for ‘Transmit Inhibit’ under certain conditions (e.g. when the channel is in use by other users) in which case, the channel busy tone will sound when you press the PTT key to indicate that transmission is inhibited.

If your radio is equipped with a transmit time out timer (TOT), a warning tone will sound a few seconds before the transmission is cut off. The radio may be programmed to inhibit retransmission within a preset time.

Call Termination

Hang up the microphone in its holder when your conversation has ended.
