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.
