Introduction
CAUTION: When using telephone equipment, there are basic safety instructions that should always be followed. Refer to the IMPORTANT SAFETY
INSTRUCTIONS provided with this product and save them for future reference.
Your Four-Line Speakerphone is a full-featured phone ideally suited for home-office use. It is designed to receive calls on up to four
incoming telephone lines and to serve up to 16 station users. Your phone features 16 memory locations, 94 phone book memories, hold,
conference call, intercom, call transfer, Caller ID display, and speakerphone capabilities.
This telephone is designed to be simple to use, however, you can reach its full potential more quickly by taking a few minutes to read this
user’s guide.
IMPORTANT: In order to use all of the features of this unit, you must subscribe to either the standard Name/Number Caller ID Service or Call Waiting Caller ID Service.
To know who is calling while you are on the phone, you must subscribe to Call Waiting Caller ID Service.
NOTE: FEATURES AND OPERATIONS PERTAINING TO CALLER ID DO NOT APPLY TO Model 25403.

Connections & Setup
Telephone Jack Requirements
To use this phone, you will need an RJ11C (CA11A) (for a single line) or a RJ14C (CA14A)
(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.

Connections & Setup
Installing the Phone
The phone may be connected to two 2-line (RJ14C) wall jacks or four single line (RJ11C)
wall jacks to accomodate all four lines.
1. Choose an area near an electrical outlet and telephone wall jack. Your phone should be
placed on a level surface, such as a table top or desk.
2. Install 3 AA-size alkaline batteries (not included) for back up power in the event of a
power failure.
•Use a screwdriver to loosen and lift up the battery compartment door located on
the bottom of the phone.
•Insert the batteries as shown on the diagram inside the battery compartment.
•Snap the battery compartment door back into place and tighten the screw.
NOTE: If the low battery icon appears in the display, you need to replace the batteries. It is important
that you replace them as soon as possible to maintain unit operation when electrical power is off. As a
precaution, you may want to write down any stored information you do not want erased.
IMPORTANT: If you are not going to use the telephone for more than 30 days, remove the batteries
because they can leak and damage the unit.

3. Plug the AC power supply cord into an electrical outlet and the DC connector into the back of the base.
CAUTION: Use only the ATLINKS USA 5-2495 power supply that is compatible with this unit. Using other power supplies may
