• When "NG" is displayed at First screen (version information, etc)
• How the data on cumulative HDD-on time are processed in memory
Storage place:
Backup SRAM, Flash ROM
Timing of referring to the data on cumulative HDD-on time:
When the power is turned on, the backup SRAM is referred to
regarding the data on cumulative HDD-on time, and the data are stored in the RAM. If referring to the backup SRAM fails, the flash
ROM is referred to.
Timing of updating the data on cumulative HDD-on time:
While the HDD is on, the data on cumulative HDD-on time in the RAM
is updated every 3 seconds, and every time updating is executed the data are stored in the backup SRAM. When the power is turned off,
the data are stored in the flash ROM.
How to clear the data on cumulative HDD-on time
Backup SRAM:
When the HDD Identification Setting is performed, the data on cumulative HDD-on time are automatically cleared.
The HDD Identification Setting is automatically performed when the CPRM setting is performed on the CPRM setting screen (to
display the CPRM setting screen, press the ESC then the STEREO keys), or when the HDD is initialized by pressing the "ESC" key
then the the "one-shot memory" key.
Notes:
The data on cumulative HDD-on time are not cleared when resetting to factory-preset values is performed.
The data on cumulative HDD-on time are not cleared when the system-control computer software is downloaded.
Flash ROM:
The data on cumulative HDD-on time cannot be cleared (they are not cleared even if resetting to factory-preset values is
performed or if the system-control computer software is downloaded).
Note:
The data on cumulative HDD-on time in the flash ROM can be cleared if you clear the data in the backup SRAM following the
above-mentioned procedures then turn off the power of the unit, because the data in the backup SRAM are stored in the flash
ROM when the power is turned off.
