Caller ID
How Caller ID operates
When you receive a call, the name and/or phone number of the caller
will alternately appear in the display, beginning just before the second
ring. The information will continue to be displayed until you pick up
the handset, or until the fax answers automatically if it is in FAX mode.
Note: Some caller ID services may not provide the name of the caller. In
this case, only the phone number will appear.
