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:15-100m
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
 

This is the position for the antenna to be connected.

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)
