Adding and registering handsets/headsets
Your telephone can support up to 12 DECT 6.0 cordless handsets (AT&T model
CL80111, sold separately) or up to ten cordless handsets and two cordless headsets (sold separately). Visit www.telephones.att.com/headsets
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 handset, see below.
The handsets provided within your product box are already registered as HANDSET 1 and so forth. Additional handsets are assigned numbers in the sequential order they are registered (up to HANDSET 12).
