three "beeps" are heard, the receiver is in the receive mode.
2.To enter the wireless pairing transmit mode(transmitter): switch to channel 2 ( 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 red light begins to
flash and three "beeps" are heard, the transmitter is in the transmit mode.
3.Press the transmitter's PTT button once. The red light will flash, indicating data transmission.
4.The receiver's red and green lights will alternate, indicating data reception. Once the receiver has completed receiving the data, it will
automatically restart.
5.The receiver's automatic restart signifies completion of the pairing process. Manually turn off the transmitter and then turn it on again
to exit the wireless pairing transmit mode. The wireless pairing is now complete, allowing communication on the same channel.
How can RT86A talk with RT86?
Long press the [PF2] key(the bottom side key) of RT86A to turn on the radio and you will hear a "beep" sound, radio will switch to RT86
frequency to talk with RT86 directly. While maintaining the RT86 frequency, each startup will make a different "beep" sound from the
RT86A startup to distinguish it; Press the [PF2] key of RT86A again to turn on the radio and you will hear two "beeps" to switch to
RT86A frequency. At the same time, each startup will restore the original RT86A startup sound.
One-key Enable/Disable CTCSS/DCS
After turning off the radio, press and hold side key 2 + PTT to power on. A single "beep" indicates that the sub-tone for all channels
has been disabled. Repeat this action to hear two "beeps", enabling the sub-tone for all channels again. (These are temporary actions;
the original factory settings for sub-tone will be retained upon software reading.)
One-key Group Call Enable/Disable
Long-press the PF1/PF2 button configured for group calls to activate the one-key group call function. Once enabled, all radios will be
switched to the group call channel for transmission and reception, regardless of their original channel settings. The group call channel
can be selected via the programming software's optional features. The software also allows setting the recovery time and PTT response
(when enabled, releasing the button after initiating the group call allows continued communication via the PTT button until the
recovery time elapses). Release the PF1/PF2 button to exit the one-touch group call mode.
Scrambling
In the Audio settings of the software,select scrambling.Both parties can clearly hear the content of the incoming call signal only when
the scrambling protocols match and can be mutually decrypted by each other.
Region Switching
To switch regions, briefly press or hold PF1 or PF2, which are pre-set for region switching. Upon hearing a single "beep", it indicates
switching to Region 1. Repeat the same action, and upon hearing two consecutive "beeps", it signifies switching to Region 2 (Note:
Region 2 does not have factory-set frequencies and requires software programming with approved and authorized frequency points).
CTCSS/DCS
The frequency programming software can be used to set CTCSS (sub-tone) or DCS(digital sub-tone) signaling on the radio's channels.
When a channel is configured with a CTCSS or DCS, squelch will only open upon receiving a signal with the matching CTCSS or DCS. If
different types of CTCSS/DCS encoding are used within the same channel, only the green light will illuminate, indicating that squelch is
not open. CTCSS offers 50 groups, whereas DCS provides 105 groups for both forward and reverse directions, totaling 210 groups in
total. (The software also allows editing of non-standard CTCSS/DCS settings for normal use.)
