BEFORE YOU BEGIN
About Caller Identification (Caller ID)
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.
About the Call Log
This phone assigns each incoming call a number from 1 to 50.
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 34, for more details.
If you answer a call before call information appears on the screen,
it will not appear in the call log.

This product is compatible with the AT&T 2300 Expansion Handset.
You may use up to three 2300 units (purchased separately) with this
phone. Follow the instructions provided with the additional handset(s)
