Adding and registering a headset  
The TL7610 accommodates up to two cordless headsets. You  
can add a new headset (TL7600, purchased separately) to the  
headset base at any time. You must register each new headset  
with the headset base before use (see page 19).  
-OR-  
• You can register a maximum of two TL7610 headsets to  
an AT&T DECT 6.0 cordless telephone. The telephone base  
recognizes and counts a headset the same as a handset.  
When you register the TL7610 to an AT&T DECT 6.0 cordless  
telephone, the headset base acts only as a charger for the  
headset. The LIFTER AUDIO ADJUST, VOLUME /  
and  
MODE controls on the headset base become inactive. You can  
place the headset base anywhere you have an available power  
outlet. Do not plug in the telephone line cord; you only need  
to plug the headset base into a power outlet (see page 20).  
Refer to your telephone user's manual for the maximum  
number of handsets that you can register to the telephone  
base. If you have the maximum number of handsets registered,  
you need to follow the deregistration information in your  
user's manual.  
Visit www.telephones.att.com/headsets for a list of  
compatible cordless telephones.  
You can only register the headset to one product at a time, so  
the headset must be deregistered before registering to a headset  
base or a cordless telephone (see page 21).  
The first headset provided with your TL7610 has a blue ON/OFF  
light. When you register a second headset, the ON/OFF light of  
that headset turns orange to help you identify the headsets.

You may need to deregister your headsets if:  
You have two registered headsets and need to replace one of them.  
-OR-  
You wish to change the designated headset number and/or the  
color of the ON/OFF lights of your registered headsets.  
You must first deregister both headsets, and then register again  
each headset you wish to use individually.  
Please read carefully through all the instructions on this page  
before beginning the deregistration process.  
To deregister all headsets  
This procedure deregisters all the items registered to the

VOLUME /+, VOLUME /–, MUTE. When you see the MUTE  
light on the headset base turns off and the headset(s) ON/OFF  
light flashes twice every five seconds, the deregistration is  
successful. Repeat this step on the other headset if there is any.  
To register the headset(s) to the headset base again, see page 19.  
NOTES:  
If the deregistration process failed, you may need to reset the system and  
try again. Remove the headset from the headset base and press ON/OFF.  
Place the headset back into the headset base. You may also reset by  
unplugging the power from the headset base, then waiting a few seconds,  
and plugging it back in.

Especially about cordless headsets  
Privacy: The same features that make a cordless headset  
convenient create some limitations. Telephone calls are  
transmitted between the headset base and the headset by  
radio waves, so there is a possibility that your cordless headset  
conversations could be intercepted by radio receiving equipment  
within range of the cordless headset. For this reason, you  
should not think of cordless headset conversations as being  
as private as those on corded telephones.  
• Electrical power: The headset base of this cordless headset  
must be connected to a working electrical outlet which is not  
controlled by a wall switch. Calls cannot be made from the  
headset if the headset base is unplugged or switched off,  
or if the electrical power is interrupted.  
46  
 
Appendix  
Important safety information  
• Potential TV interference: Some cordless headsets operate  
at frequencies that may cause interference to TVs and VCRs.  
To minimize or prevent such interference, do not place the  
headset base of the cordless headset near or on top of a TV  
or VCR. If interference is experienced, moving the cordless  
headset farther away from the TV or VCR will often reduce or  
eliminate the interference.  
• Rechargeable batteries: This product contains nickel-cadmium,  
nickel-metal hydride or lithium-ion 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.  
• Lithium-ion 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  
lithium-ion 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 Li-ion batteries.  
CAUTION:  
• There may be a risk of detonation if you use a wrong type of  
battery. Use only the battery provided or replacement battery  
purchased separately (model BT191545 “BYD SL531732”).  
• Change this product's batteries only in accordance with the  
instructions and limitations specified in this manual.  
• As with any batteries, do not allow conductive materials such  
as rings, bracelets or keys to come in contact with the metallic  
parts of the battery. The battery or conductor may overheat  
and cause harm.

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 cordless telephones and  
implanted cardiac pacemakers. Supported by the U.S. Food and  
Drug Administration, WTR recommends to physicians that:  
Pacemaker patients  
• Should keep cordless telephones at least six inches from the  
pacemaker.  
• Should NOT place cordless telephones directly over the  
pacemaker, such as in a breast pocket, when it is turned ON.  
• Should use the cordless telephone at the ear opposite the  
pacemaker.  
WTR’s evaluation did not identify any risk to bystanders with  
pacemakers from other persons using cordless telephones.

DECT 6.0 digital technology  
Digital Enhanced Cordless Telecommunications (DECT) 6.0 is a new  
frequency band that transmits your voice across multiple channels.  
This technology provides superior quality of voice and sound, high  
protection against wiretapping and better range than 2.4 GHz and  
5.8 GHz phone systems, while not interfering with wireless routers.  
Operating range  
This cordless headset operates within the maximum power allowed by  
the Federal Communications Commission (FCC). Even so, this headset  
and headset base can communicate over only a certain distance  
— which can vary with the locations of the headset base and headset,  
the weather, and the construction of your home or office.  
Extended range and clarity  
Experience the best in long-range coverage and clarity, provided by  
a unique antenna design and advances in noise-filtering technology.  
The TL7610 is a fully cordless DECT 6.0 headset offering a range  
of up to 500 feet. Open range test was performed by Wyle  
Laboratories, an independent commercial test facility. “Up to 500  
feet” cordless headset range refers to the maximum open field  
range. Actual range may vary depending on intervening obstacles.  
Sound level protection technology conforms to the current  
regulations and is used to filter out the loud and high-pitched noises.
