<br />Working Mode Description:
<br />
<br />1. Instantaneous mode: Press the remote control button to activate the relay, release the remote control button, and the relay is deactivated.
<br />
<br />2. Switching mode: Press and release the remote control button, and the relay is activated; Press and release the remote control button again, and the relay is deactivated.
<br />
<br />Clear All Stored Transmitters:
<br />
<br />1. Notes: After clearing the stored transmitter, all transmitters need to be re learned by the receiver.
<br />
<br />2. Press the learning button on the receiver 8 times, and the code will be cleared.
<br />
<br />3. Learning transmitter ( instantaneous mode):
<br />
<br />The 2 button emitter is programmed as an instantaneous mode transmitter.
<br />
<br />1) Step 1: 
<br />
<br />Press and release the learning key on the receiver.
<br />
<br />Wait for a moment, LED will close, indicating you enter the learning state.
<br />
<br />2) Step 2: 
<br />
<br />Press and release the first button on the transmitter, and the LED on the receiver board will flash and then go out, indicating that the button has been learned.
<br />
<br />3) Step 3: 
<br />
<br />Press and release the second button to light the LED again.
<br />
<br />Wait for 3 seconds, LED will light up again, indicating that the system is ready to use.
<br />
<br />4. Learning transmitter ( switching mode):
<br />
<br />Program the 2 button emitter to toggle.
<br />
<br />1) Step 1:
<br />
<br />Press and release the learning key on the receiver TWICE.
<br />
<br />Wait for a moment, LED will close, indicating you enter the learning state.
<br />
<br />2) Step 2: 
<br />
<br />The button is learned.
<br />
<br />3) Step 3: 
<br />
<br />Then press and release the second button, and the LED lights up again.
<br />
<br />Wait for 3 seconds, and the LED indicator will turn on again, indicating that the system is ready to use.
<br />
<br />5. Notes: The two button emitter can only be used as switching or instantaneous.
<br />
<br />One mode per 2 button emitters.
<br />
<br />If you want the control panel to learn the remote control, you must press the "A" and "B" buttons, rather than just press one of them. 
<br />
<br />However, you can program another emitter in another mode.
