Equipment Approval Information
Your telephone equipment is approved for connection to the Public Switched Telephone
Network and is in compliance with parts 15 and 68, FCC Rules and Regulations and the
Technical Requirements for Telephone Terminal Equipment published by ACTA.
1 Notification to the Local Telephone Company
On the bottom of this equipment is a label indicating, among other information, the
US number and Ringer Equivalence Number (REN) for the equipment. You must, upon
request, provide this information to your telephone company.
The REN is useful in determining the number of devices you may connect to your
telephone line and still have all of these devices ring when your telephone number is
called. In most (but not all) areas, the sum of the RENs of all devices connected to one
line should not exceed 5. To be certain of the number of devices you may
connect to your line as determined by the REN, you should contact your local
telephone company.
A plug and jack used to connect this equipment to the premises wiring and telephone
network must comply with the applicable FCC Part 68 rules and requirements adopted
by the ACTA. A compliant telephone cord and modular plug is provided with this
product. It is designed to be connected to a compatible modular jack that is also
compliant. See installation instructions for details.
Notes
• This equipment may not be used on coin service provided by the telephone company.
• Party lines are subject to state tariffs, and therefore, you may not be able to use your
own telephone equipment if you are on a party line. Check with your local telephone
company.
• Notice must be given to the telephone company upon permanent disconnection of
your telephone from your line.
• If your home has specially wired alarm equipment connected to the telephone line,
ensure the installation of this product does not disable your alarm equipment. If you

Interference Information
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference; and (2) This device
must accept any interference received, including interference that may cause undesired
operation.
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna (that is, the antenna for radio or television
that is “receiving” the interference).
• Reorient or relocate and increase the separation between the telecommunications
equipment and receiving antenna.
• Connect the telecommunications equipment into an outlet on a circuit different from
that to which the receiving antenna is connected.
If these measures do not eliminate the interference, please consult your dealer or an
experienced radio/television technician for additional suggestions. Also, the Federal
Communications Commission has prepared a helpful booklet, “How To Identify and Resolve
Radio/TV Interference Problems.” This booklet is available from the U.S. Government
Printing Office, Washington, D.C. 20402. Please specify stock number 004-000-00345-4
when ordering copies.
Notice: The changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
FCC RF Radiation Exposure Statement
This equipment complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a
minimum distance of 20 centimeters between the radiator and your body. This transmitter
must not be co-located or operated in conjunction with any other antenna or
transmitter.”
For body worn operation, this phone has been tested and meets the FCC RF exposure
guidelines when used with the belt clip supplied with this product. Use of other
accessories may not ensure compliance with FCC RF exposure guidelines.

Important Information
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. It
also features an Auto Attendant function, which will pick up and redirect incoming calls to
other extensions in the system per the caller’s input. It is possible to enhance your phone
to a cordless feature with the additional purchase of the H5401 accessory handset
and module.
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 Caller ID features of this telephone, you must subscribe
to two separate services available from your local telephone company: the standard Name/
Number Caller ID Service to know who is calling when the phone rings and Call Waiting
Caller ID Service to know who is calling while you are on the phone.
NOTE: Features and options pertaining to Caller ID do not apply to Model 25423.

Parts Checklist
Make sure your package includes the following items:
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
or office. 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 25423,
25424, 25425, 25413, 25414, 25415, 25403 and 25404 models are
compatible for full system operation. Connecting phones other
than the 25423, 25424, 25425, 25413, 25414, 25415, 25403 and
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.
