Setting the Encryption Key (encryption word)

0 For the procedure to call the Security Settings screen on the display, see steps 1 through 3 of
page 2-11.
0 Do not leave the machine with the setting screen of Administrator Settings left shown on the display. If
it is absolutely necessary to leave the machine, be sure first to log off from the Administrator Settings.
0 To prevent data from leaking as a result of reinstallation of the HDD on another machine, a unique value
that varies from one machine to another must be set for the encryption key.
0 Do not set any number that can easily be guessed from birthdays, employee identification numbers,
and the like for the Encryption Key. Try to change the Encryption Key at regular intervals.

in a backup medium in advance. Execution of HDD Format will also reset the setting values of different
functions to the default values. Set the Enhanced Security Mode to [ON] again. For the functions whose
settings are reset to the default values, see page 2-10.
