5. Matching Transmitter:
1. Match code: 
When the receiver module is powered, hold the learning button and the LED indicator blinks, then press any button of remote control or power a transmitter module to launch, if indicator flashes 3 times, match code successfully. Maximum 20 remote controls / transmitter modules can be matched.

2. Delete code:
Hold learning button till the indicator LED lights and then off, delete successfully.

3. Set working mode:
S1 & S2 program the sequence as follows:
S1 Short Circuit→ Toggle
S2 Short Circuit→ Latching
S1 & S2 both not short→ Momentary

6. Short Introduction of Working Modes
The following introduction will describe how momentary, latching and toggle working using example of typical two channel receiver. The transmitter button A controls channel 1 while transmitter button B controls channel 2.

1. Toggle - Press A > Channel 1 ON and remains ON, Press A again > Channel 1 OFF
2. Momentary - Press and hold A > Channel 1 ON, Release A > Channel 1 OFF
3. Latching - Press A > Channel 1 ON and remains ON while Channel 2 OFF, Press B > Channel 2 ON and remains ON while Channel 1 OFF
