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 10 cordless handsets and 2 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).
Register a handset to the telephone base
Before you begin registration, put the handset you wish to register near the
telephone base. Make sure the handset shows To register, see manual.
On the telephone base, press MENU/SELECT.

On the telephone base, use qCID or pDIR to scroll to >Registration, then
press MENU/SELECT.
The handset shows To register, see manual. Press # (pound key) on the
handset. Both the handset and the telephone base show Registering...
Please wait and the IN USE light turns on.
After a while, both the handset and the telephone base beep and the IN
USE light turns off. Handset Registered shows on both the handset and
telephone base. The handset is now registered with the telephone base.
If registration fails, the system will automatically try to register again. If
registration fails after the third try, Registration failed appears on both
screens before returning to idle mode. This may take up to five minutes
to occur. Please start again from Step 1 above.
NOTES:
You cannot register a handset if any other system handset is in use.
If you try to register more than 12 handsets to the telephone base, the telephone base shows
Registration slots are full and sounds 2 beeps.
