Caller ID
Caller ID operation
Missed (new) calls indicator
When you have calls that have not been reviewed, the 
handset idle screen shows XX MISSED CALLS.
All entries that have not been reviewed are counted as 
missed (new) calls. Each time you review a caller ID history 
entry marked NEW, the number of missed 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/CLEAR for four seconds 
when the handset is idle. All the entries in the caller ID 
history are considered old (reviewed), and the missed calls 
message goes away.
