Product Introduction:
1.Operating Voltage:4.5-5.5V (input port) VCC:connects with power positive;GND:connects with power negative
2.Output Way: the module power on defaults output low level;after pressing the remote control,it will
 output high level; OUT1-OUT4 are respectively 4-channel output ports.
3.Max Output Current:every channel max output current is within 10mA
4.Quiescent Operating Current:3mA
5.Receiver Board Size:20*30*6mm
6.Receiving Distance:15-50m
7.Operating Mode:self-lock,inching,interlock modes can be set freely
8.Operating Indication:D1 (learning indicator lamp and receiving signal indicator lamp)
9.Output Level:output high level is equal to or less than VCC voltage

Learning Method:
1.After power on,press the learning key,the learning indicator lamp will flash for once; it represents the first channel trigger is successful;then press the key on remote control you want to learn,the learning indicator lamp will flash for twice,it represents the first channel learning is successful.

2.After power on,press the learning key,the learning indicator lamp will flash for twice; it represents the second channel trigger is successful;then press the key on remote control you want to learn,the learning indicator lamp will flash for twice, it represents the second channel learning is successful.

3.After power on,press the learning key,the learning indicator lamp will flash for three times;it represents the third channel trigger is successful;then press the key on remote control you want to learn,the learning indicator lamp will flash for twice,it represents the third channel learning is successful.
 

4.After power on,press the learning key,the learning indicator lamp will flash for four times; it represents the fourth channel trigger is successful;then press the key on remote control you want to learn,the learning indicator lamp will flash for twice,it represents the fourth channel learning is successful.

5.Clear Way:when power off,press the learning key;then power on,the learning indicator lamp will flash for four times;it represents module clear is successful.

Self-lock,Inching,Interlock Function Switch Operation:
1.Interlock: when power off,press the learning key and then power on;the learning indicator lamp will flash for once,and loosen the key;then it sets interlock output (press the key on remote control,the corresponding channel has output while other channels are closed and no output)

2.Self-lock: when power off,press the learning key and then power on;the learning indicator lamp will flash for twice,and loosen the key;then it sets self-lock output (press the key on remote control,the corresponding channel negation and exerts on impact on other channels state;loosen the remote control,the output state will be remained)

3.Inching: when power off,press the learning key and then power on;the learning indicator lamp will flash for three times, and loosen the key;then it sets inching output (press the key on remote control,the corresponding channels have output;if loosen the remote control,the output will be stopped)
