Connections & Setup
Telephone Jack Requirements
To use this phone, you will need an RJ11C (for a single line) or a RJ14C (for two lines) type
modular phone jack, which might look like the one pictured here, installed in your home. If
you don’t have either modular jack, call your local phone company to find out how to get
one installed.
VERY IMPORTANT: In order to achieve full system operation (i.e. intercom, page, etc.), Line 1 must be
connected and must be common to all phones connected to the system. Only other 25403 or 25404
models are compatible for full system operation. Connecting phones other than the 25403/25404 to
Line 1 may inhibit the intercom and paging operations.
For proper operation of intercom, page function, etc., DO NOT connect a DSL modem to Line 1.
To transfer a call from one station to another, the two stations should be connected to the same line.
