Information about caller ID with call waiting
This product has a caller ID function with call 
waiting feature which works with service from 
your local telephone company.
Caller ID with call waiting lets you see the name 
and telephone number of the caller before 
answering the telephone, even when on another 
call.
It may be necessary to change your telephone 
service to use this feature. Contact your telephone 
company 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 wait-
ing service.
• You do not have any caller ID or call waiting
services.
This product can be used with regular caller ID 
service, or this product’s other features can be 
used 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.
Depending on your service, you may see the caller’s 
number or the caller’s name and number. 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. 
The time and date are sent by the telephone company 
along with the call information.
