(before you change it .you need turn OFF the power. Until you have changed it, then turn ON the power again, or the State will not be changed)
Momentary———-Jumper on “ 3 & 4 Pin ”
Toggle—————-Jumper “ 1 & 2 Pin ”
Latched————–Take away the Jumper or put the Jumper on 1 Pin
Momentary————Press the Transmitter button A, the receiver relay A is ON, release button A; the receiver relay A is OFF, the same as B/C/D. 4CH are independent.
Toggle—————Press transmitter button A for 1 time, the receiver relay A is ON, press button A again, the receiver relay A is OFF, the same as B/C/D. 4CH are independent.
Press transmitter button A, the receiver relay A is ON, the relay B/C/D is OFF.
Press transmitter button B, the receiver relay B is ON, the relay A/C/D is OFF.
Press transmitter button C, the receiver relay C is ON, the relay A/B/D is OFF
Press transmitter button D, the receiver relay D is ON, the relay A/B/C is OFF.
It also mean .Latched only can keep 1CH ON .and it will often have 1CH is ON.
Input power for the Receiver .keep pressing the Learning Button until the Led indicator is ON . Then press transmitter any Button, the Led indicator OFF, then you press any button of the transmitter ,you heard the relay respond ,it mean learning successfully.
Keep pressing the Learning Button on the receiver until the LED indicator from ON to OFF, it mean the code have been cleared successfully.
