[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)
