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.

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.  
Wall plate  
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  
Modular  
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.  
telephone line

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.  
Important Installation Information  
Never install telephone wiring during a lightning storm.  
Never install telephone jacks in wet locations unless the jack is specifically designed for  
wet locations.  
Never touch non-insulated telephone wires or terminals, unless the telephone line is  
disconnected from the network.

Important Installation Guidelines  
Install telephone near both a telephone (modular) jack and an electrical power outlet.  
Avoid sources of noise, such as a window by a busy street, and electrical noise, such as  
motors, microwave ovens, and fluorescent lighting.  
Avoid heat sources, such as heating air ducts, heating appliances, radiators, and direct  
sunlight.  
Avoid areas of excessive moisture or extremely low temperature.  
Avoid dusty locations.  
Avoid other cordless telephones or personal computers.  
CAUTION: Always disconnect all phone cords from the base unit before battery  
installation or replacement.  
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.  
IMPORTANT: Install batteries and connect the AC power supply to the base unit as  
outlined in steps 1 through 3 below prior to connecting the telephone line cords to  
insure for proper base station ID assignment.  
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 4 AAA-size alkaline batteries (not included) for back up power in the event of a  
power failure.  
• Insert a flat bladed screw driver into the battery door latch recess  
area and gently pry upward to release the battery door from the  
base cabinet bottom.  
• Insert the batteries as shown on the diagram inside the battery  
compartment.  
• Position the two (2) battery door tabs into the base cabinet bottom slots and push  
downward until the door latch “snaps” closed.  
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.

Connections & Setup  
3. Plug the power supply cord into the power jack on the back of the base and the other  
end into an electrical outlet.  
CAUTION: To reduce risk of personal injury, fire, or damage use only the 5-2777 power  
adaptor listed in the user’s guide. This power adaptor is intended to be correctly  
orientated in a vertical or floor mount position.  
4. Connect the telephone line cords:  
If you have two dual line wall jacks installed in your home or office, plug one end of  
the straight telephone line cord tagged as “LINE 1+2” into the jack marked LINE 1 + 2  
and one end of the other straight line cord into the other jack on the back of the base.  
Plug the other end of each line cord into the dual-line wall jacks.  
If you have four single-line wall jacks installed in your home or office, you must use  
adaptors/couplers (not included) to combine the four single telephone lines into two  
dual lines. The adaptor/coupler may look similar to the one pictured here and can be  
purchased from your local telephone products retailer.  
NOTE: To use four lines, you must have four telephone lines with unique telephone numbers.  
If you only have one telephone line, this phone will still operate, but only as a single line  
telephone.  
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.  
NOTE:  
• If the phone cannot find an ID, determine if there are too many phones connected to the  
system. A maximum of 16 phones can be connected in the system.  
11  
 
Connections & Setup  
• The Phone ID (01 to 16) is unique. When more than one phone using the same Phone ID is  
detected, only one phone with that ID will be valid. The phone IDs for the other phone(s) is  
automatically erased, and the phone(s) intercom indicators blink. You must use the Menu  
options to select a new Phone ID for each phone.  
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. For proper operation of intercom, page function, etc., DO NOT connect a  
DSL modem to Line 1.  
• 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 25423, 25424 and/or 25425 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 25423, 25424, or 25425 units for these features to  
work properly. You may choose to share or privatize lines 2, 3 and 4.  
5. Connect the handset cord:  
Connect one end of the coiled handset cord to the jack on the side of the base and the  
other end into the jack in the handset, and place 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 ma-  
chine, computer modem, answering system, 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.  
IMPORTANT: Be sure to switch the fax machine back to the normal line when you are done  
because outside callers who do not know that you have switched lines will not be able to  
reach your fax machine if they dial the line 4 number.

Connections & Setup  
System Verification  
Use the following procedures to test system configuration and identify possible line con-  
nection errors. The phone must be connected to the power outlet, Line 1 must be con-  
nected to the LINE 1 + 2 jack, and the phone must have a phone ID.  
VERY IMPORTANT: In order to achieve full system operation (i.e. intercom, page, etc.), Line  
1 must be connected and common to all phones on the system. Only other 25423, 25424,  
25425, 25413, 25414, 25415, 25403 and 25404 models are fully compatible.

If the power cord is not plugged into the unit, and the battery is available, the unit enters  
Battery Operation Mode. In this mode, the unit fully supports all operational features,  
except the intercom call function and cordless handset.  
NOTE: Under battery operation mode, the RF module (optional for use with cordless handset)  
is not supported.  
Operation without Power  
If the power cord is not plugged into the unit and no battery is installed, the unit enters  
into No Power Operation mode. in this mode, the user may:  
1) use the handset to manually make a call on line 1 only,  
2) answer a call on line 1 with the handset.  
Cordless Phone Option  
It is possible to enhance your phone to a cordless feature with the additional purchase of  
the H5401 accessory handset and module. The H5401 is packaged with an RF module, when  
the module is properly inserted into the back of the 25425 base, the antenna icon on the  
display will illuminate.  
Troubleshooting Guide

Check or repeat installation steps:  
Make sure the telephone line cords are connected to the phone and the wall jack. Make  
sure the line cords are not damaged.  
Make sure the hook switch pops up when the handset is lifted.  
Check the SPEAKER button. Make sure the indicator is off.  
Disconnect the phone from the wall jack and connect another phone to the same jack.  
If there is no dial tone in the second phone, the problem might be your wiring or local  
service.

noise (for example, motors or fluorescent lamps).  
DO NOT expose to direct sunlight or moisture.  
Avoid dropping the handset, as well as other rough treatment to the phone.
