Enabling the Encryption Settings
The machine cannot be operated while data is being encrypted.
Once the encryption process starts, it cannot be stopped. Make sure that the machine's main power is not turned off while the encryption process is in progress. When the optional hard disk is installed, the hard disk will be damaged and all data on it will be unusable if the machine's main power is turned off during the encryption process.
The encryption key is required for data recovery if the machine malfunctions. Be sure to store the encryption key safely for retrieving backup data.
Encryption starts after you have completed the control panel procedure and rebooted the machine by turning the main power switch off and on. If both the Erase All Memory function and the encryption function are specified, encryption starts after the data that is stored on the hard disk has been overwritten and the machine has been rebooted by turning the main power switch on and off.
When the optional hard disk is installed, the process will take up to 6 hours 45 minutes if you use Erase All Memory and encryption simultaneously, and select overwrite 3 times for "Random Numbers". Re-encrypting from an already encrypted state takes the same amount of time.
The "Erase All Memory" function also clears the machine's security settings, so that neither machine nor user administration will be possible. Ensure that users do not save any data on the machine after "Erase All Memory" has completed.
When the optional hard disk is installed, rebooting will be faster if there is no data to carry over to the hard disk and if encryption is set to [Format All Data], even if all data on the hard disk is formatted. Before you perform encryption, we recommend you back up important data such as documents stored on the hard disk.
