Adding and registering a headset

Registration options

The TL7610 headset comes pre-registered to the headset base.

There are two registration options, as described below.

Option 1: The TL7610 supports up to two cordless headsets. You can register a TL7600 (purchased separately) headset or a previously deregistered TL7600/TL7610 headset to your TL7610 headset base (see page 19).

Option 2: You can deregister your TL7610 headset (see page

21) and then register it to an AT&T DECT 6.0 cordless telephone (see page 20). You can register a maximum of two headsets (TL7610/TL7600) to a cordless telephone.

The telephone base recognizes and counts a headset the same as a handset. When you register the headset 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.

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.

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.

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.

47

Appendix


The RBRC TM 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.
