How call history works
Information about the last 65 incoming calls is
stored in the call history. The most recent call has
the highest entry number. (For example, if two
calls have been received, the call with the entry
number 02 in the call history is the more recent
one.) You can review the call history to find out
who has called, return the call or save the caller's
name and number into the directory or two-touch
memory locations.
When the call history is full, the oldest entry
is deleted to make room for new incoming call
information.
If a call is answered before the information
appears on the screen, it is not saved in the call
history.
