4: SIMPLE
This is the simple overwriting method. It takes the shortest time to erase data.
Key in the level number to display "<" next to it.
(At this time, if "0" is entered, the screen returns to the initial one of the Assist Mode.)
Press the [START] button to display the reconfirmation screen, and then press the [START] button
again to start overwriting.
[G] Erasing SRAM securely (Erase SRAM Securely)
This function is used before discarding the SRAM board (for the SYS board).
It overwrites all the used areas on the SRAM board with the selected data, and makes it unusable.
Immediately after selecting this function, the processing starts and is completed.
[H] Clearing service tech password (Clear Service Tech)
This function is needed after the HDD is replaced.
When the HDD is replaced, the service tech password stored in the new one is set as a blank.
Therefore, its password is copied to the SRAM board so that both passwords become the same with
this function. The setting is enabled when the equipment is started up in the normal mode after
performing this function.
