Getting started
Registering the headset
You must register your new TL7600 headset with one of the
following models before use:
AT&T DECT cordless headset TL7610/TL7611 (see page 6).
You can register a maximum of two headsets to each headset
base.
-OR-
A compatible AT&T DECT cordless telephone (see page 7).
You can register a maximum of two headsets to each cordless
telephone.
The telephone base recognizes and counts a headset the same as
a handset. 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 de-registration information in your telephone
user’s manual.
Visit www.telephones.att.com for a list of compatible
telephones.
The first headset provided with your TL7610/TL7611 has a
blue ON/OFF light. When you register a second headset, the
ON/OFF light of the headset turns orange to help you identify
the headsets.
You can only register the headset to one product at a time, so
the headset must be unregistered before registering to a headset
base or a cordless phone.
NOTE: See pages 25 and 26 for instructions on de-registering.
