How to match the transmitter and receiver? 
1. Delete existing data: Press learning button(on the receiver) 8 times. Response: LED flashes 7 times. 
2. Learning remote code: press learning button(on the receiver) once, twice or three times (see below). 
LED turns on: learning mode is active. Press any button of the remote control. 
LED indicator flashes three times: learning successfully completed. 
3. Test: after the above operation , the receiver board can be controlled by the remote control. 
More transmitters with different IDs can be learned and stored additionally, starting with step 2. 
A mixture of different modes is possible. 

Button usage (sets mode and starts pairing process): 
Press once: Inching mode (Momentary Mode) 
Press twice: self-Lock Mode (Toggle-Mode of the 4 Channels) 
Press three times: interlocked mode (selected channel active and be cleared, if another channel becomes active)
