IMPORTANT CALLER ID INFORMATION

To use the phone’s Caller ID and Call Waiting features, you must be in an area where Caller ID and Call Waiting services are available and you must subscribe to the services.

Where Caller ID is offered, one or more of the following options are generally available:

•caller’s number only

•caller’s name only

•caller’s name and number

For the phone’s Caller ID memory dial feature to operate, you must receive the caller’s number.

Important: Cordless phones generally require AC power to op- erate. You should also have a corded phone that does not re- quire AC power to operate so you can still make and receive calls if there is an AC power failure.

Your telephone operates on standard radio frequencies as allo- cated by the FCC. Even though the access protection code pre- vents unauthorized use of your phone line, it is possible for other radio units operating on similar frequencies within a cer- tain area to unintentionally intercept your conversations and/or cause interference. This lack of privacy can occur with any cordless phone.
