Please read the instructions carefully before using Wireless Doorbell.

1. Hold Music Button over 3 seconds, it will trigger clean pairing function, so wrongly believed the product damage, but is not. We improved the manual and extended 3 seconds to 5 seconds.
2. The span of 4 levels volume is more wider, no longer concentrated in short interval, so that it can be more quieter or more louder.
3.The communication range is farther and the ability to penetrate the wall was enhanced.

Use in Out-Of-The-Box Mode (Work on default ringtone):
Step1: Insert the receiver into the socket.
Step2: Find a suitable location, stick the transmitter or fix it with a screw (Tips: remove the battery protective film), thus ok.

NOTE:
1. For multi-transmitters: Repeat Step1-2 to register another transmitters to this receiver. Thus all of transmitters have been registered to this receiver and trigger different tune.
2. For multi-receivers: Please set receiver one by one, to register each transmitter to each receiver.
3. Can not install transmitter on the metal, because built-in antenna can not close to metal.
