My telephone 
does not work 
at all.
There is no dial 
tone.
Make sure the power adapter is securely plugged into 
an outlet not controlled by a wall switch.
Make sure the telephone line cord is plugged firmly 
into the telephone base and the modular wall jack.
Unplug the telephone’s electrical power. Wait for 
approximately  5 seconds, then plug it back in. Allow 
up to one minute for the telephone to synchronize.
Disconnect the telephone base from the telephone 
line wall jack and plug in a working telephone. If this 
telephone does not work, the problem is probably 
in the wiring or the local service. Call the telephone 
service provider.
First, try all the above suggestions. Also inspect the 
coiled handset cord connections at both ends.
The telephone line cord might be malfunctioning. Try 
installing a new telephone line cord.
Disconnect the telephone base from the telephone jack 
and connect a different telephone. If there is no dial tone 
on the telephone either, the problem is in your wiring or 
local service. Contact your telephone service provider.
Make sure HOLD is not pressed.
If there is no dial tone when the HEADSET key is 
pressed, make sure the headset is firmly connected in 
the headset jack.
First, try all the above suggestions in the There is no 
dial tone section.
Make sure there is a dial tone before dialing. It is 
normal if the telephone takes a second or two to 
synchronize before producing a dial tone. Wait an extra 
second before dialing.
Check that all the telephones connected to the same 
telephone line are hung up.
If the other telephones in your home are having the 
same problem, the problem is in the wiring or local 
service. Contact your telephone service provider 
(charges may apply).

Appendix
Troubleshooting
Eliminate any background noise. Noise from a 
television, radio, or other appliances may cause the 
telephone to not dial out properly. If you cannot 
eliminate the background noise, first try muting the 
telephone before dialing, or dialing from another room 
in your home with less background noise.
There is no spare battery in the telephone or the 
battery power is low.
Remove and re-install the battery and use it normally.
If the above measures do not correct the problem, the 
battery may need to be replaced.
Make sure the ringer is on (see page 32).
Make sure the telephone line cord and power adapter 
are plugged in properly (pages  0-  ).
There may be too many extension telephones on 
the telephone line to allow all of them to ring 
simultaneously. Try unplugging some of them.
If the other telephones in your home are having the 
same problem, the problem is in the wiring or local 
service. Contact the telephone service provider (charges 
may apply).
Other electronic products can cause interference 
to your telephone. Try installing your telephone as 
far away as possible from the following electronic 
devices: wireless routers, radios, radio towers, pager 
towers, cellular telephones, digital telephones, room 
monitors, televisions, VCRs, personal computers, kitchen 
appliances, and other cordless telephones.
Test a working telephone at the same telephone jack. If 
another telephone has the same problem, the problem 
is in the telephone jack. Contact your telephone service 
provider (charges may apply).
The telephone line cord might be malfunctioning. Try 
installing a new telephone line cord.
Appliances or other cordless telephones plugged into 
the same circuit as the telephone base can cause 
interference. Try moving the appliance or telephone 
base to another outlet.

telephones.
If you have a headset plugged into the telephone, try 
unplugging it and firmly plugging it in again.
If your telephone is plugged in with a modem or a 
surge protector, plug the telephone (or modem/surge 
protector) into a different location. If this doesn't 
solve the problem, relocate your telephone or modem 
farther apart from each other, or use a different surge 
protector. 
Disconnect the telephone base from the modular jack 
and plug in another corded telephone. If the calls are 
still not clear, the problem is probably in the wiring 
or local service. Contact your local service company 
(charges may apply).
Do you have DSL service? If yes, you need to have a 
DSL filter installed. Contact your DSL service provider 
for a DSL filter.

Appendix
FCC and ACTA information
If this equipment was approved for connection to the telephone network prior 
to July 23, 200 , it complies with Part 68 of the Federal Communications 
Commission (FCC) rules. If the equipment was approved after that date, 
it complies with the Part 68 rules and with Technical Requirements for 
Connection of Equipment to the Telephone Network adopted by the 
Administrative Council for Terminal Attachments (ACTA). We are required to 
provide you with the following information.
1. Product identifier and REN information
The label on the back or bottom of this equipment contains, among other 
things, an identifier indicating product approval and the Ringer Equivalence 
Number (REN). This information must be provided to your telephone service 
provider upon request. For equipment approved prior to July 23, 200  , the 
product identifier is preceded by the phrase “FCC Reg No.” and the REN 
is listed separately. For equipment approved after that date, the product 
identifier is preceded by “US” and a colon (:), and the REN is encoded in the 
product identifier without a decimal point as the sixth and seventh characters 
following the colon. For example, the product identifier US:AAAEQ03T 23XYZ 
would indicate a REN of 0.3.
The REN is used to determine how many devices you may connect to your 
telephone line and still have them ring when you are called. In most, but not 
all areas, the sum of all RENS should be five (5.0) or less. You may want to 
contact your telephone service provider for more information.
2. Connection and use with the nationwide telephone network
The plug and jack used to connect this equipment to the premises wiring and 
the telephone network must comply with the applicable Part 68 rules and 
technical requirements adopted by 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. An RJ  jack should 
normally be used for connecting to a single line and an RJ
 4 jack for two 
lines, see installation instructions in the user’s manual. This equipment may 
not be used with coin telephone lines or with party lines. If you have specially 
wired alarm dialing equipment connected to your telephone line, ensure the 
connection of this equipment does not disable your alarm equipment. If you 
have questions about what will disable the alarm equipment, consult your 
telephone service provider or qualified installer.
3. Repair instructions
If this equipment is malfunctioning, it must be unplugged from the modular 
jack until the problem has been corrected. Repairs to this telephone 
equipment can only be made by the manufacturer or its authorized agents. 
For repair procedures, follow the instructions outlined under the limited 
warranty.

FCC and ACTA information
4. Rights of the telephone service provider
If this equipment is causing harm to the telephone network, the telephone 
service provider may temporarily discontinue your telephone service. The 
telephone service provider is required to notify you before interrupting 
service. If advance notice is not practical, you will be notified as soon as 
possible. You will be given the opportunity to correct the problem and the 
telephone service provider is required to inform you of your right to file a 
complaint with the FCC. Your telephone service provider may make changes 
in its facilities, equipment, operation, or procedures that could affect the 
proper functioning of this product. The telephone service provider is required 
to notify you if such changes are planned.
5. Hearing aid compatibility
If this product is equipped with a corded or cordless handset, it is hearing aid 
compatible.
6. Programming/testing of emergency numbers
If this product has memory dialing locations, you may choose to store police, 
fire department and emergency medical service telephone numbers in these 
locations. If you do, please keep three things in mind:
We recommend that you also write the telephone number on the directory 
card (if applicable), so that you can still dial the emergency number 
manually if the memory dialing feature does not work.
This feature is provided only as a convenience, and the manufacturer 
assumes no responsibility for customer reliance upon the memory feature.
Testing the emergency telephone numbers you have stored is not 
recommended. However, if you do make a call to an emergency number:
You must remain on the line and briefly explain the reason for the call 
before hanging up.
Programming/testing of emergency numbers should be performed 
during off-peak hours, such as in the early morning or late evening, 
when the emergency services tend to be less busy.
