Adding and registering headsets
You must register your new TL8900/TL8901 headset to one of
the following devices before use:
X
SynJ SB67138 base (see pages 9-10).
X
A compatible AT&T DECT 6.0 telephone (see pages 11-12).
Visit
https://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 13-15) 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
telephone.
