(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.

 Latched------------------

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.

Learning Method:
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.
