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.
