Adding and registering handsets/headsets
Your telephone can support up to five DECT 6.0 cordless handsets (AT&T
model
B102-0
, sold separately) or up to three cordless handsets and 2
cordless headsets (sold separately). Visit

for a list of compatible DECT
6.0 cordless headsets. Each new handset or headset must be registered to
the telephone base before use. You must register each handset or headset
separately.
To register a cordless headset to this telephone system, please refer to the
user’s manual of the cordless headset for more details. To register a cordless

sequential order they are registered (up to
HANDSET 5
).
