Shared caller ID log 
The caller ID log is stored in the telephone base, 
and is shared by all handsets. Changes made at 
any one handset will be reflected in all.
NOTE: Only one handset can review the caller ID log or  
   directory at a time. If another handset attempts to enter  
   the directory or caller ID log, it will display NOT    
   AVAILABLE AT THIS TIME.
How caller ID works 
If you subscribe to caller ID service provided by your 
local  telephone  company,  information  about  each 
caller will be displayed between the first and second 
ring. Information about the last 50 incoming calls is 
stored in the call log. You can review the call log to 
find out who has called, easily return the call, or copy 
the caller’s name and number into your directory.
When the call log is full, the oldest entry is deleted 
to make room for new incoming call information.
If you answer a call before the information appears 
on the screen, it will not be saved in the call log.
NOTE: Caller ID features will work only if both you and the 
  caller are in areas offering caller ID service, and if both tele- 
  phone companies use compatible equipment.
