TRANSMITTER PARING
QK-R022 is an intelligent self-learning remote control receiver. It allows the operator paring the
remote controller with QK-R022 by learning the communication code. Up to 30 remote controller can
be paired with one
QK-R022 can always release the paired remote controller by clearing the communication code. After
this releasing process, all of the remote controller will lost the communication with paired QK-R022
until new learning process performed again.
4.1 Clear communication code
Power up the module, press and hold the ‘SET’ button for about 5 seconds. The LED will blink three
times indicating the communication code cleared. By now, all codes of transmitters which had been
stored are cleared. All paired remote controllers are released.
