Method/step of installing remote control on projector curtain: 1. Look carefully at the holes on the receiver of the remote control. There are 5 holes in total, one hole is in the center line, one is the rising hole, and the other is the falling hole; 2. Disassemble the wire-controlled switch of the electric curtain with a screwdriver. There is a connecting line inside. Take a closer look. One line is the center line with adhesive tape or sleeve, or the one that is not cut short is the center line (because the center line of each electric curtain is different); Cut it to the center line hole on the remote control receiver; 3. There are also three wires. One is the ground wire, which is not needed and can be cut short. The other two are connected to the rising and falling holes of the receiver of the remote control, which can be connected casually; 4. There are also three power supply holes. The power supply holes only need to be connected to two wires. One is the ground wire and does not need to be connected. Cut short the lower section of the electric curtain wire control switch and connect it to the receiver power supply of the remote controller. The two holes with signs can be connected to complete.
