1. Connect the incoming line of the live wire to the input end of the receiver, and connect the output end of the receiver to the power amplifier.
2. Connect a capacitor in parallel with the power amplifier at the terminal near the lamp (it must be close to the lamp, and other positions are useless).
3. After the switch is connected, pry open the toughened glass panel at the pry openings of the upper and lower shells with a screwdriver, put the lower shell into the 86 inner box, fix the lower shell on the inner box with a cross screwdriver through the left and right screws, and cover the toughened glass panel.
