Easy to install with cord strip. Install 2*AAA batteries for receiver and transmitter, move the switch to “1” is low detecting sensitivity, “2” is high detecting sensitivity, “0” on receiver is OFF, “1” is low volume, “2” is high volume.
Transmitter/Doorbell button with the same model.
No wires or cables required.
Place the doorbell chimes near baby, the receiver can be placed or carried within the range of wireless signal receiving (the detecting light would twinkle every 5 seconds), in view of electricity saving and the possible effect of wireless to baby, you can switch “Test on” to “test off” to turn off the test signal which won’t be sent until the baby cries.
Humanity design, once the baby cry or other noise occurs, the receiver may start to make electronic crying noise and the transmitter won’t.
