The transmitter can be fixed in two ways. The first method is to paste it on the wall with 3M double-sided adhesive tape. There is a warm prompt on the double-sided adhesive tape: Do not install it on the metal door. The metal will weaken the signal.

The second way is to first remove the bottom shell of the transmitter with a screwdriver, then fix the bottom shell to the wall with expansion screws, and finally buckle the transmitter into the bottom shell.

When you press the button with your finger pointing at the transmitter, you will feel that the button is very elastic and has an obvious pressing range. It feels great! And accompanied by the sound of "creaking". After receiving the signal, the receiver immediately sounds "ding dong", and the indicator light flashes, which is very sensitive.
