 Function

1. Momentary: Press and hold = on, release = off
2. Toggle / Self-lock: Press 1 button = on, press the same button again = off
3. Latched / inter-lock: Press 1 button = on, press another button = off

Clear code and learn code

1. Learn Press the learning button 1 time, the learning LED lights up, then press the transmitter key to learn. The learning led blinks and turns off. It means learning correctly.
2. Clear Press the learning button for 5 seconds, the learning LED flashes and turns off, which means the code has been cleared.
