OPERATION OVERVIEW

Your dealer can program your transceiver for DTMF/2-Tone/DMS signalling or

This transceiver can handle up to 250 groups with 250 channels in each group.
Groups, channels, and their functions are programmed by your dealer.

SWITCHING POWER ON/ OFF

Press the switch to switch the transceiver ON (or OFF).

ADJUSTING THE VOLUME

Press the keys programmed as Volume Up and Volume Down to adjust the
volume. Volume Up increases the volume; Volume Down decreases it.

SELECTING A GROUP/ CHANNEL

Select the desired group and channel using the keys programmed with the
Group and Channel functions.

MAKING A CALL

Note: If the selected channel is programmed with QT (Quiet Talk) or DQT (Digital Quiet Talk), remove
the microphone from the microphone hanger to disable QT or DQT, then listen to the channel to make
sure nobody is talking on it. If the selected channel is not programmed with QT or DQT, simply listen to
the channel to make sure nobody is talking on it; in this case, you need not remove the microphone from
its hanger.
1 Select your desired group and channel.
• If the channel is busy, wait until it becomes free.
2 Press and hold the PTT switch, then speak into the microphone. Release the
PTT switch to receive.
• For best sound quality at the receiving station, hold the microphone approximately
3 ~ 4 cm (1.5 inches) from your mouth.
3 When your conversation is finished, return the microphone to its hanger.

RECEIVING A CALL

1 Select your desired group and channel. (If the Scan function has been
programmed, you can switch it ON or OFF as desired.)
