* If the registry has been backed up, the backed up registry will be used.

Description
Data in process will be deleted. Perform a Reset if there are any problems such
as no response for an input or incorrect program behaviors.
All data except for data stored in the Flash and the SD card will be deleted.
Perform a Full reset if a problem still exists after reset.
The BHT without the battery connected leads the backup battery to discharge
resulting in data corruption in the RAM.
The BHT performs a full reset at the next startup if data corruption is detected.
The stored registry will be deleted in addition to the RAM data at OS update,
due to incompatibility with the registry between OS versions.
