Wanted See video on Amazon.com, ordered and delivered was a wireless doorbell with a transmitter and a receiver for an elderly lady. The attachment of the transmitter is done using the enclosed, tailor-made, double-sided adhesive pad. The receiver is simply plugged into the socket. In the transmitter there is already a CR2032 coin cell. It then operates the approximately 9.3 cm high x 4.4 cm wide x 1.4 cm deep channels, the previously selected ring tone sounds. You can choose from 36 ring tones. Discontinued be the recipient not only ring tones, but also the volume.
Transmitter and receiver receiver work perfectly, "sparks" by a massive stone wall. Due to the ease of use of the recipient and the volume this bell is definitely something for the older ones among us.
