Basic Operation
Power On: Turn the On-Off/Volume Control Knob clockwise until a click is heard to turn on the
radio. The radio will make a sound of “Di…” If programmed, the current channel number will be
annunciated.
Adjusting the Volume
Press Monitor button to enter into the monitor state. Then rotate ON/OFF/Volume knob to adjust
the volume.
Selecting a Channel
Turn the channel selector knob to your desired channel. If voice annunciation has been set, the
radio will annunciate the current channel number. You will hear voice from the speaker while
Page 8
receiving valid signals.
Note: The 16th channel is the scan channel.
Sending a Call
To make a call, press and hold the PTT button and speak to the microphone in normal voice.
Please keep your mouth 3 - 5 cm away from the microphone to realize the best communication
quality. Release PTT button to receive.
Scan function
Scan ON
When rotated the channel selector to the 16th channel, the radio begins to scan. It stops when
the signal is received.
Note: When the radio is in 16th channel, the signal will be received later because of the scan.
Scan OFF
When rotated the channel selector to 1-15 channels, the radio stops to scan.
Explanations:
After scan pauses, there are two ways to resume scanning, which can be set in PC software:
1. Time operate: After pausing on an active channel, the radio will resume scanning after a
preprogrammed delay. The scan delay time can be preset from 0.5 to 5 seconds.
2. Carrier operate: After pausing on an active channel, the radio will resume scanning after a
preprogrammed delay after the channel becomes inactive. The scan delay time can be preset
from 0.5 to 5 seconds.
Revert channel: Press PTT to transmit during the scan. The transmitting channels used have the
following options:
Page 9
1. Last Rx channel
When pressing PTT button during scanning, the radio will transmit from the last channel that
received a call.
Note: After the last scan, the radio will stay at one channel. This channel is the last Rx channel.
2. Last Rx channel + Currently working channel
When pressing PTT button during scanning, the radio will transmit from the last channel that
received a call; when pressing PTT button in scan off state, the radio will transmit from the
currently working channel.
3. Selected channel
When pressing PTT button during scanning, the radio will transmit from the first channel in
the scan list.
4. Selected channel + Currently working channel
When pressing PTT button during scanning, the radio will transmit from the first channel in
the scan list.
When pressing PTT button in scan off state, the radio will transmit from the currently
working channel.
5. Priority channel
Press PTT button, the radio will transmit from the priority channel in the scan list.
6. Priority channel + Currently working channel
When pressing PTT button during scanning, the radio will transmit from the priority channel
in the scan list.
When pressing PTT button in scan off state, the radio will transmit from the currently
working channel.
Note:
Currently working channel refers to the channel described in the following conditions:
1. When the radio receives the signal, and does not start to scan, it stays at one channel. This
channel is currently working channel.
2. When the signal cannot be received, the radio will stay at one channel within the designated
times. This channel is currently working channel.
3. When pressing PTT button to transmit, the radio will stay at one channel. This channel is
currently working channel.
4. When releasing PTT button to finish transmitting, the radio will stay at one channel within
designated pause time. This channel is currently working channel.
Selected channel: the first channel in the scan list.

Auxiliary Functions
Note: The relevant setting about TOT can be set by PC software.
Time-Out Timer (TOT)
The time-out-timer can prevent the user from continuously talking overlong and prevent the
radio from heating due to continuous transmitting.
If you continuously transmit longer than the preset TOT time, the radio will make an alert tone
and stop transmitting.
TOT Pre-alert
The radio will make an alert tone in advance before the TOT terminates the transmission. After
the alert tone, when the time of transmission exceeds the pre-set time, the TOT timer will act.
TOT Rekey Time
A period during when the radio is forbidden to transmit after its overtime activity.
During the period, if the PTT button is pressed, an alert tone will be sounded, and the
transmission is forbidden.
TOT Reset Time
The time delay from releasing the PTT button to the resetting of the timer is limited.
The countdown will go on if the time after releasing the PTT key is shorter than the reset
time.
Busy Channel Lockout (BCL)
If the channel on which a user attempts to transmit is being used by another party, BCL function
restricts the transmission in order to avoid interfering with the other parties' communication, and
the radio will make an alert tone, and returns to the receiving state.
Default setting: Disabled, i.e. the radio can transmit at any time.
Battery Saving
The battery saving function can reduce power consumption of the radio when no signal is
received and no operation is conducted (no button is pressed and no knob is turned).
If the radio hasn't receive any signal or no operation is being conducted for 16 seconds, the radio
Page 11
will enter Battery Saving Mode. When a signal is received or any operation occurs, the radio will
exit the Battery Saving Mode automatically.
Low Battery Warning
When the battery voltage drops to the pre-set value, low battery warning tone sounds every 10
seconds. And the radio turns off automatically in very low battery. You need to recharge or
change the battery.
Squelch Level
The squelch function is enabled to mute the speaker when there is no signal to be received.
Enable squelch, you can hear the background noise from the speaker. Disable squelch, the noise
cannot be heard.
The squelch level determines when the squelch function should be on. If the selected level is too
high, the weak signal cannot be heard; if the selected level is too low, the signal will be mixed
with the background noise. Squelch level can be set by PC software. Range: 0-9. The default
setting is 5.
CTCSS/DSC
CTCSS/DSC of PT260 can be programmed by PC software. The range of CTCSS/DSC signal tone can
be 67~254, 1/D023~D777 respectively.
CTCSS/DCS tones may have been pre-programmed on some radio channels. A CTCSS/DCS tone is
a sub-audible tone, which allows you to realize selected call and group call.
When you receive a signal that has a tone different from the one set on your radio, you will not
hear the signal. Likewise, signals that you transmit will only be received by parties whose
CTCSS/DCS tones are the same as yours.
Voice Annunciation
If voice notice is enable in standby state, press voice notice button to hear which channel the
radio stays.
Wired clone
Enable wired clone function. If the radio enters into this mode, it will not exit to the user mode
until you restart the radio. The steps of wired clone are as follows:
1. Press and hold Monitor button to turn on the radio. Red LED flashes after 2 seconds, and the
Page 12
radio enters into clone mode.
2. Press Monitor button, Red LED flashes, and start to clone the data. Red LED lights off when
finishing clone.
Note: You can enable or disable wired clone function by PC software. Once this function is
disabled, the radio cannot enter into wired clone mode.
The default setting: Disabled.
