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 have questions
about what will disable alarm equipment, consult your telephone company or a qualified installer.
2Rights of the Telephone Company
Should your equipment cause trouble on your line which may harm the telephone network, the telephone company shall, where practicable, notify you that temporary discontinuance of service may
be required. Where prior notice is not practicable and the circumstances warrant such action, the telephone company may temporarily discontinue service immediately. In case of such temporary
discontinuance, the telephone company must: (1) promptly notify you of such temporary discontinuance; (2) afford you the opportunity to correct the situation; and (3) inform you of your right to
bring a complaint to the Commission pursuant to procedures set forth in Subpart E of Part 68, FCC Rules and Regulations.
The telephone company may make changes in its communications facilities, equipment, operations or procedures where such action is required in the operation of its business and not inconsistent
with FCC Rules and Regulations. If these changes are expected to affect the use or performance of your telephone equipment, the telephone company must give you adequate notice, in writing, to allow
you to maintain uninterrupted service.
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, “HowTo 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.

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.

Unit Initialization:
After you connect the power supply and Line 1 to the unit, the system automatically searches for and sets up a
phone ID. To set your own Phone ID, or change your phone ID, follow the steps in the Phone ID section.
You may connect up to 16 RCA 25404 and/or RCA 25403 phones to the system at one time. Features like
intercom, page and call transfer may be used among the units, but Line 1 must be common for all 25404 or
25403 units for these features to work properly. You may choose to share or privatize lines 2, 3 and 4.
Connections & Setup
If you have four single-line wall jacks installed in your home/office, you must use adapters/couplers (not
included) to combine the four single telephone lines into two dual lines. The adapter/coupler may look similar to
the one pictured here and can be purchased from your local telephone products retailer.

the handset in the cradle.
6. Check for a dial tone:
Lift the handset and listen for a dial tone. If you hear a dial tone, the phone is properly installed.
Data Port
This phone has a data port jack to connect an auxiliary phone device, such as a fax machine, computer modem, answering machine, or even a
cordless phone.
The data port switch on the back of the phone controls the data port jack so you can choose line 1, line 2, line 3, or line 4.
Use the data port to hook up your fax machine, for example, and then set the data port switch to line 4 in order to receive faxes on the
phone number for line 4.
If you are talking to someone on line 4 and want that person to fax something to you, change the data port switch to line 2 or line 3, and
give the person on-line the phone number for line 2 or line 3. Your fax machine now can receive calls on line 2, line 3, or line 4.
