Information about caller ID with call waiting

Caller ID with call waiting lets you see the name and telephone number of the
caller before answering the call, even while on another call.
It may be necessary to change your telephone service to use this feature.
Contact your telephone service provider if:
You have both caller ID and call waiting, but as separate services (you may

need to combine these services).
You have only caller ID service, or only call waiting service.

You don't subscribe to caller ID or call waiting services.

There are fees for caller ID services. In addition, services 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 service providers use
compatible equipment. The time and date, along with the call information, are
from the telephone service provider.
Caller ID information may not be available for every incoming call. Callers may
intentionally block their names and/or telephone numbers. You can only view
and store a maximum of 15 digits or characters of every caller ID log entry.
NOTE: You can use this product with regular caller ID service, or you can use this product's
other features without subscribing to caller ID or combined caller ID with call waiting service.
