OPERATION OVERVIEW
Your dealer can program your transceiver for either
Trunking Format or Conventional Format.
■Trunking Format
This format can handle up to 32 systems with up to
250 groups in each system. The transceiver can be
used in both trunked mode and conventional mode.
Systems, groups, and their functions are
programmed by your dealer.
■Conventional Format
This format can handle up to 250 groups with 250
channels in each group. The transceiver can be
used only in conventional mode. Groups, channels,
and their functions are programmed by your dealer.

11
OPERATING BASICS
■Switching Power ON/ OFF
Turn the Power switch/ Volume control clockwise to
switch the transceiver ON.
Turn the Power switch/ Volume control
counterclockwise to switch the transceiver OFF.
If the Radio Password function is programmed,
“PASSWORD” will appear on the display when the
power is turned ON. To unlock the transceiver, enter
the password, then press the Skey. If you enter the
wrong password, an error tone sounds and the
transceiver remains locked. The password can
contain a maximum of 6 digits.
■Adjusting the Volume
Rotate the Power switch/ Volume control to adjust
the volume. Clockwise increases the volume and
counterclockwise decreases it.
■Selecting a System/ Group/ Channel
Select the desired system and group (Trunking
Format) using the encoder and the keys programmed
with System or Group Up/ Down.
Select the desired group and channel (Conventional
Format) using the encoder and the keys programmed
with Group or Channel Up/ Down.

12
■Time-out Timer (TOT)
The purpose of the Time-out Timer is to prevent any
caller from using a channel for an extended period of
time.
If you continuously transmit for a period of time that
exceeds the programmed time, the transceiver will
stop transmitting and an alert tone will sound. To
stop the tone, release the PTT switch.
Your dealer can program the TOT time in the range
of 15 seconds to 10 minutes.

13
TRUNKED OPERATION (Trunking Format)
■Placing a Dispatch Call
1Select the desired system and group using the
encoder and the System or Group keys.
2Press the PTT switch.
3If a tone does not sound, communication is
possible;start speaking 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.
■Receiving a Dispatch Call
1Select the desired system and group using the
encoder and the System or Group keys. (If the
Scan function has been programmed, you can
switch it ON or OFF as desired.)
2When you hear the dispatcher’s voice, readjust
the volume as necessary.

14
CONVENTIONAL OPERATION (Trunking Format)
■Transmitting
1Select the desired system and group using the
encoder and the System or Group keys.
2Press the key programmed as Monitor to check
whether or not the channel is free.
•If the channel is busy, wait until it becomes free.
3Press 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.
■Receiving
1Select the desired system and group using the
encoder and the System or Group keys. (If the
Scan function has been programmed, you can
switch it ON or OFF as desired.)
2When you hear the dispatcher’s voice, readjust
the volume as necessary.

15
SYSTEM SCAN (Trunking Format)
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 a predetermined
time delay if the PTT switch is released and no further
signal is received.
■Scanning Trunked Systems
When scanning trunked systems, the revert groups
and the groups not locked out of the scanning
sequence are scanned. See “GROUP SCAN” on
page 17.
■Scanning Conventional Systems
When scanning conventional systems, the revert
groups and the groups not locked out of the scanning
sequence are scanned. See “GROUP SCAN” on
page 17.
