About Caller ID with Call Waiting

This product has a Caller ID with Call Waiting feature that lets you see who’s calling while you’re on another call.

To use this feature, you may need to change your phone service. Contact your local phone service provider if you have:

no Caller ID or Call Waiting service

either Caller ID or Call Waiting as a single service

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

You can also use this product with regular Caller ID service or no Caller ID services. To turn off this phone’s Caller ID with Call Waiting feature, see the FEATURE SETUP section of this manual.

There may be fees for Caller ID services, and such services may not be available in all areas. This phone 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 Home and Local Area Codes

Always program your home area code, and, if you need them, your local area codes (up to four — see page 9). Programming these area codes will change how numbers are displayed in the call history, and will allow for correct operation of the Display Dial feature (see page 39).
