Adding and registering handsets/headsets/
speakerphones
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
separately). Visit www.telephones.att.com/accessories for
a list of compatible DECT 6.0 cordless headsets and speakerphones.
Each new handset, headset or speakerphone must be registered
to the telephone base before use. You must register each handset,
headset or speakerphone separately.
To register a cordless headset or speakerphone 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).
