Alarm Recording that starts recording automatically by tracing
back to the time prior to the input of alarm signals.
Display the [ALARM REC] menu screen to execute
PREALARM REC or PREALARM TIME. (Page 34)
„ When alarm signals are input, the alarm recording starts
simultaneously.
• When the alarm recording starts, the pre-alarm recording
for the set time is performed automatically.
• When alarm recordings that have pre-alarms have been
selected, the display will jump to the starting position of the
pre-alarm recordings during the alarm search.
• There are cases where pre-alarm recording cannot be
performed at the specified time if alarm signals are input
immediately after pre-alarm recording has been started.
• There are cases where the alarm’s recording time is longer
than actually specified when the time set for this is shorter
than the value set for pre-alarm recording.
• The alarm recording parameters for pre-alarm recording
are only activated when recording is suspended.
