Troubleshooting
The layout of your home or office may be limiting the 
operating range. Try moving the telephone base to another 
location, preferably on an upper floor.
If other phones in your home are having the same problem, 
contact your telephone service provider (charges may apply).
Test a working phone at the phone jack. If another phone has 
the same problem, contact your telephone service provider 
(charges may apply).
Other electronic products such as HAM radios and other DECT 
phones can cause interference with your cordless phone. Try 
installing your phone as far away as possible from these types 
of electronic devices.
Remove the battery. Replace it and place the cordless handset 
into the telephone base. Allow up to one minute for the 
handset to reestablish its connection with the telephone base. 
Your line cord may be defective. Try installing a new line cord.
My calls cut in and out while I’m using my cordless handset.
Other electronic products such as HAM radios and other DECT 
phones can cause interference to your cordless telephone. Try 
installing your telephone as far away as possible from these 
types of electronic devices.
Do not install this phone near a microwave oven or on 
the same electrical outlet. You may experience decreased 
performance while the microwave oven is operating.
If you plug your phone in with a modem or surge protector, 
plug the phone (or modem/surge protector) into a different 
location. If this doesn’t solve the problem, relocate your 
phone or modem farther apart from one another, or use a 
different surge protector.
Relocate your telephone base to a higher location. The phone 
may have better reception when installed in a high area.

Troubleshooting
Disconnect the telephone base from the telephone wall jack 
and plug in a working telephone. If the other phones in your 
home are having the same problem, the problem is in your 
wiring or telephone service. Contact your telephone service 
provider (charges may apply).
Excessive background noise will cause a speakerphone to fade 
in and out. Try controlling the background noise by turning off 
any audio devices near the speakerphone. Also, try to avoid 
interrupting the person at the other end of the conversation 
while they are speaking. If background noise cannot be 
controlled, you should stop speakerphone operation and 
return to normal handset mode.
When using a speakerphone, controlling background noise 
in your environment is essential. While you are listening 
to your party press M�TE/DELETE to temporarily turn your 
microphone off. When it is your turn to speak, remember to 
press M�TE/DELETE to turn the microphone on.
My caller ID isn’t working.
Caller ID is a subscription service. You must subscribe to this 
service from your telephone service provider for this feature 
to work on your phone.
The caller must be calling from an area that supports caller ID.
Both your and your caller’s telephone service providers must 
use caller ID compatible equipment.
If you subscribe to high-speed Internet service (DSL - digital 
subscriber line) through your telephone line, you must 
install a DSL filter between the telephone line cord and the 
telephone wall jack. The filter prevents noise and caller ID 
problems resulting from DSL interference. Contact your DSL 
service provider for more information about DSL filters.

Troubleshooting
System does not receive caller ID when on a call.
Make sure you subscribe to caller ID with call waiting features 
from your telephone service provider. Caller ID features work 
only if both you and the caller are in areas offering caller  
ID service, and if both telephone service providers use 
compatible equipment.
I subscribe to a nontraditional telephone service that uses  
my computer to establish connections, and my telephone  
doesn’t work.
Make sure your computer is powered on.
Make sure your Internet connection is working properly.
Make sure that the software is installed and running for your 
nontraditional telephone service. 
Make sure to plug your USB telephone adapter into a 
dedicated USB port on your computer. Do not plug it into a 
multiple port USB hub (USB splitter) that is not powered.
In a few rare instances, the USB port on your computer may 
not have enough power. In these instances, try using a USB 
hub with its own external power supply.
If you are using a firewall, it may prevent access to your 
nontraditional telephone service provider. Contact your 
service provider for more information.
The charge light is off.
Make sure you plug the power and line cords in correctly  
and securely.
Unplug the electrical power. Wait for 15 seconds, then plug it 
back in. Allow up to one minute for the cordless handset and 
telephone base to reset.
Clean the cordless handset, charger and telephone base 
charging contacts each month with a pencil eraser or cloth.

Maintenance
Taking care of your telephone
Your cordless telephone contains sophisticated electronic 
parts, so it must be treated with care.
Avoid rough treatment.
Place the handset down gently.
Save the original packing materials to protect your telephone 
if you ever need to ship it.
Avoid water
Your telephone can be damaged if it gets wet. Do not use the 
handset in the rain, or handle it with wet hands. Do not install 
the telephone base near a sink, bathtub or shower.
Electrical storms
Electrical storms can sometimes cause power surges harmful 
to electronic equipment. For your own safety, take caution 
when using electric appliances during storms.
Cleaning your telephone
Your telephone has a durable plastic casing that should 
retain its luster for many years. Clean it only with a soft cloth 
slightly dampened with water or a mild soap.
Do not use excess water or cleaning solvents of any kind.

Important safety information
Safety information
Read and understand all instructions in the user’s manual. Observe all markings on the product.
Avoid using a telephone during a thunderstorm. There might be a slight chance of electric shock from lightning.
Do not use a telephone in the vicinity of a gas leak. Under certain circumstances, a spark may be created when the adapter is plugged into the power outlet, or when the handset is replaced in its cradle. This is a common event associated with the closing of any electrical circuit. The user should not plug the phone into a power outlet, and should not put a charged handset into the cradle, if the phone is located in an environment containing concentrations of flammable or flame-supporting gases, unless there is adequate ventilation. A spark in such an environment could create a fire or explosion. Such environments may include: medical use of oxygen without adequate ventilation; industrial gases (cleaning solvents; gasoline vapors; etc.); a leak of natural gas; etc.
Do not use this product near water, or when you are wet. For example, do not use it in a wet basement or shower, or next to a swimming pool, bathtub, kitchen sink, or laundry tub.

Important safety information
Especially about cordless telephones
Privacy: The same features that make a cordless telephone convenient create some limitations. Telephone calls are transmitted between the telephone base and the handset by radio waves, so there is a possibility that your cordless telephone conversations could be intercepted by radio receiving equipment within range of the cordless handset. For this reason, you should not think of cordless telephone conversations as being as private as those on corded telephones.
Electrical power: The telephone base of this cordless telephone must be connected to a working electrical outlet which is not controlled by a wall switch. Calls cannot be made from the handset if the telephone base is unplugged, switched off or if the electrical power is interrupted.
Potential TV interference: Some cordless telephones operate at frequencies that may cause interference to TVs and VCRs. To minimize or prevent such interference, do not place the telephone base of the cordless telephone near or on top of a TV or VCR. If interference is experienced, moving the cordless telephone farther away from the TV or VCR will often reduce or eliminate the interference.
Rechargeable batteries: This product contains nickel-metal hydride rechargeable batteries. Exercise care in handling batteries in order not to create a short circuit with conductive material such as rings, bracelets, and keys. The battery or conductor may overheat and cause harm. Observe proper polarity between the battery and the battery charger.
Nickel-metal hydride rechargeable batteries: Dispose of these batteries in a safe manner. Do not burn or puncture. Like other batteries of this type, if burned or punctured, they could release caustic material which could cause injury.
The RBRC™ Seal means that the manufacturer is voluntarily participating in an industry program to collect and recycle nickel-metal hydride rechargeable batteries when taken out of service within the United States. These batteries may be taken to a participating local retailer of replacement batteries or recycling center. Or you may call 1 (800) 8-BATTERY for locations accepting spent Ni-MH batteries.

Precautions for users of implanted cardiac pacemakers
Cardiac pacemakers (applies only to digital cordless telephones): Wireless Technology Research, LLC (WTR), an independent research entity, led a multidisciplinary evaluation of the interference between portable wireless telephones and implanted cardiac pacemakers. Supported by the U.S. Food and Drug Administration, WTR recommends to physicians that:
Pacemaker patients
Should keep wireless telephones at least six inches from the pacemaker.
Should NOT place wireless telephones directly over the pacemaker, such as in a breast pocket, when it is turned ON.
Should use the wireless telephone at the ear opposite the pacemaker.
WTR’s evaluation did not identify any risk to bystanders with pacemakers from other persons using wireless telephones.
Especially about telephone answering systems
Two-way recording: This unit does not sound warning beeps to inform the other party that the call is being recorded. To ensure that you are in compliance with any federal or state regulations regarding recording a telephone call, you should start the recording process and then inform the other party that you are recording the conversation.
