Basic Operations and Functions

Power On / Off
To turn on the power, rotate the volume control knob clockwise until a click sound is heard. To turn off the power, rotate the volume
control knob counterclockwise until a click sound is heard.
Talking
Press and hold the PTT button , the red indicator light will illuminate, and you can speak into the microphone. The other party will hear
your voice. Release the PTT button after speaking to receive the other party's message. The green indicator light will illuminate
simultaneously when receiving.
Volume Up/Down
Increase the volume by rotating the volume control knob clockwise.Decrease the volume by rotating the volume control knob
counterclockwise.
Channel Selection
To switch to the next channel,rotate the channel selector knob clockwise. To switch to the previous channel, rotate the channel
selector knob counterclockwise.
Low Battery Alert
When the voice prompt "Please Charge" is heard, accompanied by a flashing red light, it indicates that the battery voltage is below the
operating threshold. Please charge the radio.
Monitor Function On/Off
Briefly or long press the PF1/PF2 key assigned for monitoring to activate. This allows listening to the selected channel for
transmissions. Silence is indicated by a "shushing" sound. Repeat the action to deactivate.
VOX On/Off
Press the side button 1 + PTT button to turn on the device, and VOX will be quickly activated with a "beep" sound; repeat the
operation and you will hear two "beep" sounds to turn off VOX.
Channel Lock On/Off
Briefly or long press the PF1/PF2 key designated for channel lock. A single beep indicates activation, locking the channel. Repeat for
deactivation, confirmed by two beeps.
Scan Function On/Off
Briefly or long press the PF1/PF2 key programmed for scanning. A single beep initiates scanning, indicated by a flashing green light.
The radio exits scanning upon receiving a signal. Repeat to deactivate, confirmed by two beeps.
Alarm Function On/Off
Briefly or long press the PF1/PF2 key assigned for alarms to activate. Choose between local (device only) and remote (both transmitter
and receiver) alarms via programming. Press PTT to cancel.
Transmit TOT
TOT prevents extended transmissions on a single channel, safeguarding against radio damage due to continuous transmission. Upon
exceeding the preset TOT limit, the radio stops transmitting and emits an alert tone. Release the PTT switch to silence the tone and
resume receive mode.
Power Level Switching Activation
Briefly press or hold down the PF1/PF2 button configured for power level switching to activate the function. A single "beep" indicates
switching to low power, two "beeps" indicate switching to medium power, and three "beeps" indicate switching to high power.
Scrambler
Program inside software to enable the scrambler function,which is equivalent to voice encryption. The radios participating in this
function need to be enabled at the same time to hear the content clearly.
Microphone Gain Adjustment
The microphone gain can be adjusted via software to enhance or reduce the sensitivity of the radio's microphone. A higher value
results in greater sensitivity.
One-key Frequency Pairing
(Note: Compatible with RT86A and other radios without anti-cloning features. Enables frequency matching between radios with
different frequencies. One channel can be matched at a time without the need for a PC for seamless communication.)Testing procedure
with antennas, maintaining a distance of 0.5m to 1.5m, with a maximum test duration of 15 seconds:
1.Enter One-key decoding mode: With the radio turned off, press and hold the PTT button while powering on. After 3 seconds, a
"beep-beep-beep" sound will be heard accompanied by alternating red and green light flashes, announcing the current channel.
Release the PTT button to proceed.
2. Transmitter setup: Power on the transmitter and rotate the channel switch to the target channel (covering the desired frequency).
Press and hold the PTT button to activate this function . Transmit to the test receiver. When the test receiver's red light turns green, it
indicates successful transmission frequency testing and saving. The green light will remain for a period before a single "beep" confirms
successful saving. After completion, the transmitter and receiver can communicate seamlessly.
Easy Pairing (Antenna installed, test at distance of 0.5m-1.5m)
(Note: Compatible RT86A with identical RT86A models. When frequencies or CTCSS/DCS differ, all channel frequencies and CTCSS/DCS
can be copied, enabling seamless communication without the need for PC programming. The transmitter's side key functions will not be
copied by default; However,side key functions can also be optionally copied via software setting.)
1.To enter the wireless pairing receive mode(receiver): switch to channel 1 ( power on or power off both ok), turn off the radio,press
and hold side key 1 while turning on the radio. Continue holding for approximately 1 second. When the green light begins to flash and
