Overview

The Wireless Doorbell and Intercom can determine who is at the 
door from anywhere in the house. The doorbell and intercom have 
up to a 1000 foot (300 m) range and use a 900 MHz secure digital 
radio link. The intercom is compatible with various Chamberlain 
Wireless Products. The doorbell and intercom can be programmed 
to create a new network or add to an existing network.

THEORY OF OPERATION
To place a call to the intercom press the call button on the front 
of the doorbell. To answer the call press and hold the talk button 
on the intercom. Once the call is answered, a secure connection 
is made between the two devices. The call button on the doorbell 
does not need to be pressed to talk, however the talk button on 
the intercom must be held to talk. Release the talk button to hear a 
response. After 30 seconds of inactivity the doorbell and intercom 
will time out and the call is ended. If a call is not answered within 
30 seconds the intercom/doorbell will time out. Refer to the 
Operation section for more information.
