Getting started
Add and register headsets
You must register your new TL7700 headset with a compatible AT&T DECT 6.0 telephone before use (see page 9). 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 and headsets that you can register to the telephone. If you have the maximum number of handsets registered, you need to follow the deregistration information in your telephone user’s manual before you can register a headset. Visit www.telephones.att.com for a list of compatible telephones.
You can only register the headset to one product at a time. You must deregister the headset before registering it to another telephone (see page 10).
