How to Match Transmitters and Receivers
1. Delete Existing Data: Press Learning Button (on receiver) 8 times. Response: LED flashes 7 times.
2. Learn the remote code: Press the Learn button (on the receiver) once, twice or three times (see below). LED lights up: learning mode is activated. Press any button on the remote control. LED flashes three times: learning completed successfully.
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 . There can be different modes of blending. Button to use (set mode and start pairing process): Press once: Jog mode (momentary mode) Press twice: Self-locking mode (4-channel switching mode) Press three times: Interlock mode (selected channel activated and cleared, if another channel became active)
