Adding and registering handsets/headsets

Your telephone can support up to 12 DECT 6.0 cordless handsets (AT&T model TL90073, 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 your telephone base

1.Before you begin registration, make sure the handset is out of the telephone base or charger and shows To register, see user manual.

2.Put the handset you wish to register on the telephone base cradle.

3.The handset shows Registering...Please wait. It takes about 90 seconds to complete the registration process. The cordless handset displays HANDSET X Registered (X represents the registered handset number), and beeps when registration completes.

If registration fails, the system will automatically try to register again. If registration fails after the third try, the handset displays Registration failed, then To register, see user manual. This may take up to 5 minutes to occur. Please start again from Step 1 above.

For registration, put the handset on the telephone base, not the handset charger.
