CONVENTIONAL OPERATION

■

Transmitting

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

Receiving

1 Select the desired system and group using the System and Group keys.

as desired.)
2 When you hear the dispatcher's voice, readjust the volume as necessary.

SYSTEM SCAN

If the Scan function is programmed, systems can be scanned by pressing the
key programmed as Scan. When the Scan key is pressed, the SCN indicator
and "-SCAN-" or the revert system/ group number, appear on the display and
scanning starts. The systems not locked out of the scanning sequence are
scanned.
When a call is received, scanning stops and the system and group digits appear.
Press the PTT switch and speak into the microphone to respond to the call. The
transceiver will continue scanning after an adjustable time delay if the PTT
switch is released and no further signal is received.
