BASIC OPERATION
Your phone has a caller ID (CID) 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 caller 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.
