This wireless doorbell is battery operated at both receiver and pushbutton doorbell . The pushbutton doorbell is a snap to install  -  Simply use the double side tape to align and then use screws to secure the transmitter to the wall or door !

The transmitter has one  common 12 Volt battery found at many drug stores. The receiver has  two  "AA" batteries found everywhere. The batteries with normal use of 20 times per day should last about a year.

 This chime has a range of up to 260  feet ( line of sight )  with a realistically tested 150 feet transmission)  and may be carried around like a pager or put in your pocket or set on the counter or hung from a wall with a small screw or nail.

The receiver is capable of three pleasant tones:

Westminster Chime, Ding Dong ( will sound twice ) , or Classical tone.

Imagine cooking on your deck or enjoying the use of your pool without wondering when your guests will arrive. Or great if you have a loved one that is ill at the house!
