Adding and registering handsets
Your telephone can support up to 12 DECT 6.0 cordless handsets
(AT&T model CL80114, sold separately) or up to ten cordless
handsets and two cordless headsets or speakerphones (sold
www.telephones.att.com/accessories
separately). Visit
for
a list of compatible DECT 6.0 cordless headsets and speakerphones.
Each new handset or headset must be registered to the telephone
base before use. You must register each handset, headset or
speakerphone separately.
To register a cordless headset to this telephone system, please
refer to the corresponding user's manual for 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).
