The door chime receiver pairs with up to four wireless push buttons and features eight melodies — ding-dong, fanfare, good vibes, knocks, Mozart, patriotic, tango and Westminster — to customize multiple entryways with separate sounds. For additional personalization, adjust the sound level using four volume settings. The push buttons each include a  battery for easy installation and come already paired with the receiver. Instructions for multiple mounting options are also provided. To power the receiver, simply insert three C batteries — not included.
