This product has a Caller ID with Call Waiting feature that works with
service from your local phone service provider.

Caller ID with Call Waiting lets you see who’s calling before you answer 
the phone, even when you’re on another call.

You may need to change your phone service to use this feature.
Contact your phone service provider if:

•

You have both Caller ID and Call Waiting, but as separate services
(you may need combined service)

•

You have only Caller ID service, or only Call Waiting service

•

You don’t subscribe to any Caller ID or Call Waiting services.

You can use this product with regular Caller ID service, and you can 
use this product’s other features without subscribing to either Caller ID or
combined Caller ID with Call Waiting service.

There are fees for Caller ID services, and they may not be available in 
all areas.

This product can provide information only if both you and the caller 
are in areas offering Caller ID service, and if both telephone companies use
compatible equipment.

This phone assigns each incoming call a number from 1 to 50 at the
handset. The most recent call will have the lowest number. When the
memory is full, the oldest call information is deleted to make room for new
incoming call information. See CALLER ID OPERATION, beginning on page
43, for more details.

If you answer a call before call information appears on the screen, it will not
appear in the calls log.

This product is compatible with the AT&T 5800 Expansion Handset. You
may add up to five additional 5800 units (purchased separately) 
to this phone. Follow the instructions provided with the additional
handset(s) for installation and registration.

NOTE: Although you can register up to six handsets, only four can be
used at one time.
