Caller ID operation
Caller ID overview
Missed (new) calls indicator
When a handset is in idle mode and has calls that have not
been reviewed, its screen shows XX MISSED CALLS.
All unreviewed entries are counted as missed (new) calls. Each
time you review a caller ID history entry marked NEW, the
number of missed (new) calls decreases by one.
If you do not want to review the missed (new) calls one by one, but you still
want to keep them in the caller ID history, you can press and hold
OFF/ for four seconds when the handset is idle. All the entries in
CLEAR
the caller ID history are considered old (reviewed), and the missed (new) calls
counter is reset to 0.
