BEFORE YOU BEGIN
Compatibility
This AT&T 2300 expansion handset is compatible with the AT&T 2320, 2325, 2355 and 2365 telephones. You may add up to three expansion handsets to your compatible telephone, for a total of four handsets.
If you try to install a fifth handset, registration will be blocked.
About Handset Registration
Each expansion handset must be individually registered with your AT&T 2320, 2325, 2355 or 2365 base. Registration happens automatically when you place this handset fully charged into your current base.
(See INSTALLATION beginning on page 3).
The original handset that came with the base is automatically registered as Handset 1. Additional handsets will be assigned Handset 2, Handset 3 and Handset 4. You can rename the handsets by following the directions under “Handset Name” in the FEATURE SETUP section of your base telephone User’s Manual.
