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).
