Adding and registering headsets
You must register your new TL7900 headset to one of the
following devices before use:
AT&T TL7910/TL7912 cordless headset (see page 9). You can
register a maximum of two headsets to each headset base.
A compatible AT&T DECT 6.0 cordless telephone (see pages
10-11). Visit
www.telephones.att.com/headsets
for a list
of compatible telephones.
Refer to the user’s manual of your telephone for the maximum
number of handsets and headsets that you can register to the
telephone. If you have the maximum number of handsets/
headsets registered, you need to follow the deregistration
instructions (see pages 12-13) to deregister all registered devices
before you can register this new headset.
You can only register the headset to one device at a time. You
must deregister the headset before registering it to another
headset base or telephone.
