Fix event positions
An event in which the Event Fix Mode is changed from OFF to some other setting is referred to as
a master event. To change the master event, set the Event Fix Mode to OFF first, and then set the
master event.
How the events that are detected at positions other than the master event positions are displayed
varies depending on the Event Fix Mode as follows:
• When Event Fix Mode Is Set to Append Mode (Mode 1)
Events detected at positions other than the master event positions are also displayed in the
event list.
Events other than fixed events are also detected.
An earlier event is detected, so the
number of this fixed event is updated
(changes from 3 to 4).
• When Event Fix Mode Is Set to Master Mode (Mode 2)
Only the events that are detected at the master event positions are displayed in the event list.
Not detected even when an event exists.
