Coolqiya Wireless Long Range Waterproof Doorbell Alert System

Wireless Remote Multiple Doorbell, Come with 3 Receivers & 2 Transmitters

You can pair transmitters with receivers one by one for a new code to get a ring tone or expand transmitter buttons/receivers

• Please pair transmitters with receivers one by one for a new code before you install the transmitters on the door frame
• If you have installed your transmitters on the door frame, please use the small screwdriver (included) to open the transmitter and take the front cover off, and take it close to the receiver to pair them

Here's how to pair them:

• Plug one receiver into a regular socket, and pick the sound you want on this receiver
• Press and hold the volume button on this receiver for 5 seconds or so, then the receiver will blink with a "ding" sound. And then push the transmitter button at the same time (within 5seconds) to pair with the receiver. Finally, you will hear the music you set
• The same way to pair other transmitter buttons with receivers

How to split door bells up between multi-unit transmitters and receivers?

• Firstly, clear the original old code of receivers, press and hold the forward button of receivers about 5 seconds till it blink with a "ding" sound, then pair transmitters to receivers for a new code one by one again (following above steps 1-3)
• Note: For the transmitter which don't control this receiver, please don't pair, just do nothing, only pair the transmitters that need to control it.
