BASIC OPERATIONS
RECEIVING
Your dealer may have programmed QT or DQT signalling for the channel that
you select. If the channel has been programmed in this way, you will hear
transmissions from your group only. Otherwise, you will hear all the
transmissions made any stations using the same channel.
■Switching Power ON/OFF
Press the IO switch to switch the transceiver ON (or OFF).
■ Adjusting the Volume
Press the key programmed as Volume Up or Volume Down to adjust the
volume. Volume Up increases the volume and Volume Down decreases it.
■ Selecting a Channel
Select the desired channel system using the keys programmed with the Channel
Up and Down keys.
Note: TK-760G/ TK-860G features 128-channel capacity. In order to manage 128 channels easily, one
or more programmed channels can be bundled together as a group.
Your dealer may have also programmed Group Up and Down keys. In this case, please select the
desired group and channel number. Please consult your dealer for the details.

CALLING
■Monitoring the channel
Press MON key (or a key programmed as Monitor) to monitor the channel for
a few seconds to confirm that channel is not being used.
After the confirmation, hold the microphone about 3 to 4 cm (1 1/2 inches)
from your mouth, press microphone PTT , and speak in your normal speaking
voice.
Release PTT and listen to a response.
■ Busy Channel Lockout
Activated or deactivated by your dealer, this function prevents you from
interfering with other stations that my be using a channel. Pressing
microphone PTT while the selected channel is in use causes your transceiver
to generate an audible warning tone. Your transceiver is inhibited in this
situation so it will not transmit. Release microphone PTT to canel the alarm
and restore the receive mode.
■ Time-Out Timer
The purpose of the time-out timer is to automatically interrupt continuous
transmissions after a specified time elapses. Holding down microphone PTT
for longer than the programmed time causes the transceiver to stop
transmitting and generate a warning tone. Releasing microphone PTT
cancels the warning tone.

10
SCANNING CHANNELS
If the Scan function is enabled, groups or channels can be scanned by pressing
the key programmed as Scan. A Scan key can be programmed as either Single
Scan or Multi Scan by your dealer.
Single Scan monitors only the channels of a single group. Multi Scan monitors
all channels of every group. When the Scan key is pressed, the SCN indicator
and "SCAN" appear on the display and the scanning starts.
When a call is received on one of scanning channels, scanning stops and the
channel information appears on the display. Press PTT switch and speak into
the microphone to respond to the call. The transceiver will continue scanning
after an adjustable time delay, if PTT switch is released, and no further signal is
received.
■Priority Scan
Either Fixed priority scan or Selectable priority scan may be programmed by
your dealer.
•Fixed Priority Scan: The pre-programmed channel is monitored in a
certain interval while scanning. When the signal is being received on this
priority channel while scanning, you will be transfered to this priority
channel.
•Selectable Priority Scan:After you select the priority channe using
Channel Up/Down or Group Up/Down keys, press a Scan key,
programmed by your dealer. The scanning starts and the selected priority
channel is monitored in a certain interval while scanning. When the signal
is being received on the selected priority channel while scanning, you will
be transfered to this priority channel.
■Channel lockout
If the channel lockout is enabled by your dealer, you can select channels to
add or delete from the scaning channel list. When the displayed channel is
not locked out from the scanning, the add indicator A (Add) will appear on the
display.
1. Using Channel Up and Down key to select the channel that you wish to
add or delete from the scanning list.
2. Press a Delete/Add key, programmed by your dealer to add or delete the
channel to/from the scanning channel list. If the channel is in the scanning
list, A (Add) indicator will be lit on the upper right side of the display. A
(Add) indicator is disappeared from the display, the channel is no longer in
the scanning channel list.
