■ Shutdown Sequence

Before shutting OFF the power supply, it is necessary to perform the HDD completion
process (for the HDD models only. Purpose: to prevent damage on the HDD) and execute
the fixing disengagement operation. This sequential process is called "shutdown sequence".
The shutdown sequence has been manually executed with the legacy (existing) models (by
holding down the power supply switch on the Control Panel for a specific duration).
When the Main Power Switch is turned OFF with this equipment, Main Controller PCB detects
this operation to start/execute the shutdown sequence automatically.
Note that the maximum shutdown time with this equipment is 110 seconds.
NOTE:
When the power supply is stopped without advance shutdown of the equipment, or
the complete deletion process of the HDD (deletion of the primary file) failed to be
completed within the shutdown time (max. 110 sec.), data matching is checked at
startup. In such a case, startup takes up to 80 seconds. The progress bar is displayed
during the data checking.
