Caller ID with call waiting
If you subscribe to combined caller ID with call
waiting service from your local telephone com-
pany, when this feature is on, the telephone dis-

a new incoming call while on an existing call.
When this feature off, the telephone does not
display and log caller ID information, but you
can still hear one beep to remind you there is
an external call. You can press FLASH to answer
the call. Press or CID to turn this feature on
or off.
