bit to “0.”
Caution: Before resetting an alarm, always identify and remove the cause of the alarm.
If the cause cannot be removed or the alarm still persists after removing the cause,
contact IAI.
If the same error occurs again after resetting the alarm, the problem that caused the alarm
in the first place is still present.
