Appendix  
Troubleshooting  
• If the previous suggestions do not work, disconnect the  
telephone base from the telephone jack and connect the jack to  
a different phone. If there is no dial tone on that phone either,  
the problem is in your wiring or local service. Contact your  
telephone service provider.  
• Your line cord might be malfunctioning. Try installing a new line cord.  
I cannot dial out.  
• First try all the suggestions above.  
• Make sure you have a dial tone before dialing. The cordless  
handset might take a second or two to find the telephone base  
and produce a dial tone. This is normal. Wait an extra second  
before dialing.  
• Eliminate any background noise. Noise from a television, radio or  
other appliances might cause the phone to not dial out properly.  
If you cannot eliminate the background noise, try muting the  
cordless handset before dialing, or dialing from another room  
with less background noise.  
• If the other phones in your home are having the same problem,  
contact your telephone service provider (charges might apply).  
My cordless handset isn’t performing normally.  
• Make sure you plug the power cord securely into the telephone  
base. Plug the power adapter into a different, working electrical  
outlet without a wall switch.  
• Move the cordless handset closer to the telephone base. You  
might have moved out of range.  
• Reset the telephone base. 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.  
• Other electronic products can cause interference to your  
cordless phone. Try installing your phone as far away from these  
types of electronic devices as possible: television sets, VCRs, or  
other cordless telephones.

Troubleshooting  
I get noise, static, or weak signals even when I’m near the  
telephone base.  
• If you subscribe to high-speed Internet service (DSL - digital  
subscriber line) through your telephone lines, you must install a  
DSL filter between the telephone base and the telephone wall  
jack. The filter prevents noise and caller ID problems as a result  
of DSL interference. Please contact your DSL service provider for  
more information about DSL filters.  
• You may be able to improve the performance of your cordless  
phone by installing your new telephone base as far as possible  
from any other existing cordless telephone system that may  
already be installed.  
• Other electronic products can cause interference to your  
cordless phone. Try installing your phone as far away from the  
following electronic devices as possible: television sets, VCRs, or  
other cordless telephones.  
• Do not install this phone near a microwave oven or on the same  
electrical outlet. You might experience decreased performance  
while the microwave oven is operating.  
• If you plug your phone in with a modem or a surge protector,  
plug the phone (or modem/surge protector) into a different  
location. If this does not solve the problem, relocate your phone  
or modem farther apart from one another, or use a different  
surge protector.  
• Move your phone to a higher location. The phone might have  
better reception in a high area.  
• If the other phones in your home are having the same problem,  
contact your telephone service provider (charges may apply).  
I experience poor sound quality when using the speakerphone.  
• For increased sound quality while using the speakerphone, place  
the handset on a flat surface with the dial pad facing up.

CL84200/CL84250/CL84300 telephone.  
• Make sure you plug the telephone line cord securely into the  
telephone base and telephone jack. Make sure you plug in the  
power cord securely.  
• The cordless handset may be too far from the telephone base.  
• Charge the battery in the cordless handset for at least 16 hours.  
For optimum daily performance, return the cordless handset to  
the telephone base or charger when not in use.  
• You may have too many extension phones on your telephone  
line to allow all of them to ring simultaneously. Try unplugging  
some of the other phones.  
• The layout of your home or office might be limiting the  
operating range. Try moving the telephone base to another  
location, preferably on an upper floor.  
• If the other phones in your home are having the same problem,  
contact your telephone service provider (charges might apply).  
• Test a working phone at the phone jack. If another phone has  
the same problem, contact your telephone service provider  
(charges might apply).  
• Other electronic products can cause interference with your  
cordless phone. Try installing your phone as far away as possible  
from electronic devices such as television sets, VCRs, or other  
cordless telephones.  
• Completely 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.

My calls cut in and out while I’m using my cordless handset.  
• Other electronic products can cause interference with your  
cordless phone. Try installing your phone as far away from the  
following electronic devices as possible: television sets, VCRs, or  
other cordless telephones.  
• Do not install this phone near a microwave oven or on the same  
electrical outlet. You might experience decreased performance  
while the microwave oven is operating.  
• If you plug your phone in with a modem or surge protector, try  
plugging the phone (or modem/surge protector) into a different  
location. If this does not solve the problem, relocate your phone  
or modem farther apart from one another, or use a different  
surge protector.  
• Move your telephone base to a higher location. The phone  
might have better reception when installed in a high area.  
• If the other phones in your home are having the same problem,  
contact your telephone service provider (charges may apply).  
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 you 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 lines, you must install a  
DSL filter between the telephone base 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.

Maintenance  
Taking care of your telephone  
• Your cordless telephone contains sophisticated electronic parts,  
so you must treat it 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  
• You can damage your telephone 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.  
Remember that electrical appliances can cause serious injury if used when you  
are wet or standing in water. If the telephone base should fall into water, DO  
NOT RETRIEVE IT UNTIL YOU UNPLUG THE POWER CORD AND TELEPHONE LINE  
CORDS FROM THE WALL. Then pull the unit out by the unplugged cords.

AImppepndoixrtant 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:  
23  
Download from Www.Somanuals.com. All Manuals Search And Download.  
AImppepndoixrtant safety information  
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.
