Registration and deregistration  
Adding and registering handsets  
Before using a new TL90071 handset, you must register it with  
an AT&T TL92271/TL92371/TL92471/TL96271/TL96371/TL96471  
telephone system (purchased separately). These telephone  
systems can support up to 12 handsets.  
The handsets provided with your telephone system are already  
registered as ANDSET 1 and so forth. Additional handsets  
registered to the telephone system are assigned in the  
sequential order they are registered (up to ANDSET 12).  
You must register each handset separately. When first purchased,  
all expansion handsets show Put handset on �ASE to register.

The IN SE light turns off and the handset  
beeps when registration completes.  
If registration fails, the system will automatically try to register again.  
If it fails after the third try, the handset shows Registration failed,  
then Put handset on �ASE to register. This may take up to five  
minutes to occur. When the handset displays Put handset on �ASE

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 terminate speakerphone operation and  
return to normal handset mode.  
My cordless handset does not ring when I receive a call.  
Make sure that the ringer is not off. Refer to Ringer volume  
in the TL92271/TL92371/TL92471/TL96271/TL96371/  
TL96471 user’s manual provided with your 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.

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.  
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 telephone out by  
the unplugged cords.

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. Do not use liquids or aerosol sprays for cleaning.

Appendix  
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.

Important safety information  
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.
