Getting started  
Installation  
You must install and charge  
the handset battery before  
using the cordless handset.  
See pages 9-10 for easy  
instructions.  
STOP!  
Install the telephone base close to a telephone jack and a power outlet not  
controlled by a wall switch. The telephone base can be placed on a flat surface  
or vertically mounted on the wall (see pages 11-13). For optimum range and  
better reception, place the telephone base in a central and open location.  
You may hear interference if your cellular phone is too close to the telephone  
base during a CELLULAR call. Make sure that your Bluetooth enabled cellular  
phone is between one to 12 feet away from the telephone base in order  
to maintain a clear and consistent connection between your Bluetooth cell  
phone, telephone base and cell tower.  
If you subscribe to high-speed Internet service (digital subscriber line - DSL)  
through your telephone line, you must install a DSL filter between the telephone  
base and the telephone wall jack (see the following page). The filter prevents  
noise and caller ID problems caused by DSL interference. Please contact your  
DSL service provider for more information about DSL filters.  
Your product may be shipped with a protective sticker covering the handset or  
telephone base display - remove it before use.

Bluetooth  
Introducing Bluetooth  
Your new AT&T TL91178�TL91278�TL91378 telephone system with Bluetooth  
wireless technology has the following features:  
• Pair a Bluetooth enabled cell phone with the telephone base.  
• Connect a cell phone to make and receive CELLULAR calls. Only one cell  
phone can be paired and connected on a call at a time.  
• Make and receive calls using your cell phone plan while benefiting from the  
ease and comfort of your home telephone system.  
IMPORTANT INFORMATION  
• Refer to your cell phone user's manual for more information about its  
Bluetooth function.  
• Make sure that your Bluetooth enabled cellular phone is between one to  
12 feet away from the telephone base to maintain a clear and consistent  
connection between your Bluetooth cell phone, telephone base and cell  
tower.  
• Make sure that your cellular phone has sufficient signal strength. You may  
need to move the cellular phone and telephone base to a location where  
the cellular signal may be stronger.  
• Charge your Bluetooth cell phone while it is connected to the telephone  
base because your cell phone's battery will discharge faster while it is  
connected wirelessly to the telephone base.  
• Monitor your cell phone's usage because airtime is deducted from your  
cellular plan for the duration of the CELLULAR calls.  
Refer to the Bluetooth setup section (pages 18-20) to learn how to set up  
your Bluetooth device. Refer to the Handset operation section  
(pages 27-35) to learn how to operate your Bluetooth devices with your new  
AT&T telephone system with Bluetooth wireless technology. Refer to the  
Troubleshooting section (pages 62-71) if you experience difficulty when using  
the telephone system.

Glossary of terms  
Below are some terms used in this user’s manual to help you become familiar  
with using your Bluetooth devices and your new AT&T telephone system.  
Bluetooth cell phone - Refers to a mobile Bluetooth enabled cellular phone.  
CELLULAR line - The communications service provided through your  
Bluetooth enabled cellular telephone.  
HOME line - Your conventional telephone land line.  
Connected - You can only use a Bluetooth device when it is connected to the  
telephone base.  
Paired devices - Once you have paired a Bluetooth device with the telephone  
base, it is identified as registered to the telephone base. Only one Bluetooth  
cellular phone can be paired with the telephone base.  
Pairing - This refers to the process of two Bluetooth devices registering  
device information with each other. The telephone base must be paired with a  
Bluetooth cellular phone before you can use the Bluetooth device. Depending  
on the manufacturer, this process is also referred to as bonding.  
PIN - By default, the PIN is 0000 for the telephone base and for most  
Bluetooth devices. PIN information must be exchanged between Bluetooth  
devices before you can use them. The PIN is also known as a passkey  
or passcode.

Caller ID  
Caller ID operation  
This product supports caller ID services provided  
by most local telephone service companies.  
Depending on your service subscription, you may  
see the caller’s number, or the caller’s name and  
number that are sent by the telephone company  
after the first or second ring. If you also have call  
waiting service, this caller ID information shows  
when you receive a call while you are on another  
call.

NEW  
10:01AM 11/23  
Caller ID from the HOME line allows you to see  
the name, number, date and time of the incoming  
call. However, caller ID from the CELLULAR line  
only shows the number of the incoming call and  
the Bluetooth name of the paired device; date  
and time of the call are not shown.  
These services are available only if both you and  
the caller are in areas offering caller ID service,  
and if both telephone companies use compatible  
equipment.  
Contact your local telephone company and  
cellular service provider if:  
• You have both caller ID and call waiting, but as  
separate services (you may need to combine  
these services).  
• You have only caller ID service, or only call  
waiting service.  
• You don’t subscribe to any caller ID or call  
waiting services.  
You can use this product with regular caller ID  
service, or without subscribing to either caller ID  
or combined caller ID with call waiting service.

Caller ID operation  
Caller ID history information  
If you subscribe to caller ID services, provided by  
your local telephone company and�or cellular  
service provider, the caller ID history stores  
information for about the last 50 incoming calls  
for both the HOME and CELLULAR lines.

Although the caller ID history records the caller  
ID information of both lines, caller ID entries from  
the CELLULAR line only provide the incoming  
telephone number and the Bluetooth name of  
the cellular phone. If the number on the incoming  
CELLULAR call matches a number in the directory,  
the name is retrieved from the matched directory  
entry. However, if the caller's number is not  
provided from the CELLULAR line, the screen  
only shows INCOMING CALL without showing the  
Bluetooth name of the device.  
Review the caller ID history to find out who called,  
to easily return the call, or to copy the caller’s  
name and number into your directory.  
The phone deletes the oldest entry when the log  
is full to make room for new calls.  
If you answer a call before the information  
appears on the screen, it is not saved in the caller  
ID history.  
The caller ID history is stored in the telephone  
base, and is shared by all handsets. Changes made  
on any one handset is reflected in all.  
NOTE: Only one handset can review the caller ID history  
at a time. If another handset attempts to enter the  
directory or caller ID history, it shows NOT AVAILABLE  
AT THIS TIME.

NOTE: The number shown by your caller ID is in the

usually delivers ten-digit phone numbers (area code plus  
phone number). If the telephone number of the caller  
does not exactly match a number in your directory, the  
name appears as it is delivered by the phone company.  
For example, if the phone company includes the area  
code and the directory number does not, the name  
appears as delivered by the phone company.

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 stand-  
ing in water. If the telephone base should fall into water, DO NOT RETRIEVE IT UNTIL YOU UN-  
PLUG THE POWER CORD AND TELEPHONE LINE CORDS FROM THE WALL. Then pull the telephone  
out by the unplugged cords.

Important safety information  
This symbol is to alert you to important operating or servicing instructions  
that may appear in this user’s manual. Always follow basic safety precautions  
when using this product to reduce the risk of injury, fire, or electric shock.  
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 may be a slight  
chance of electric shock from lightning.  
• Do not use a telephone in the vicinity of a gas leak. If you suspect a  
gas leak, report it immediately, but use a telephone away from the area  
where the gas is leaking. If this product is a cordless model, make sure the  
telephone base is also away from the area.  
• 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. If the product comes in contact with any liquid, unplug any  
line or power cord immediately. Do not plug the product back in until it has  
dried thoroughly.  
• Install this product in a protected location where no one can trip over  
any line or power cords. Protect cords from damage or abrasion.  
• If this product does not operate normally, see the Troubleshooting  
section on pages 6�-71 of this user’s manual. If you cannot solve the  
problem, or if the product is damaged, refer to the Limited warranty

���-111. In Canada, dial 1 (866) �88-4�68.  
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.  
74  
Appendix F  
Important safety information  
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.

DECT 6.0 digital technology  
The AT&T DECT 6.0 products offer unsurpassed range performance and  
sound clarity. This is achieved through a unique antenna design and  
advances in noise-filtering technology. An independent laboratory has  
confirmed that AT&T DECT 6.0 products perform up to 45% better in range  
competitions. Now calls can be taken in the basement, backyard and garage  
with exceptional sound quality.  
Telephone operating range  
This cordless telephone operates within the maximum power allowed by  
the Federal Communications Commission (FCC). Even so, this handset and  
telephone base can communicate over only a certain distance — which can  
vary with the locations of the telephone base and handset, the weather, and  
the construction of your home or office.  
Extended range and clarity  
This telephone base comes with an antenna which gives much better clarity  
and covers a longer range than before.
