NOTE 1: The data on the hard disk is erased by overwriting it one
time. However, overwriting the data three times ensures that the
data cannot be recovered. The three times overwrite process
does take a longer amount of time to perform than the one time
overwrite process.
NOTE 2: During the overwriting process, normal operations may
run slower than normally.
For information about how to check the status during the
overwriting process, refer to the section entitled "Overwriting the
Hard Disk" in Chapter 10 of the User Guide.

Data Encryption (optional)

KEY POINT: This is an optional accessory and may be purchased
at an additional cost to the customer. For more information,
contact the Customer Support Center.
If you want the recorded data on the hard disk encrypted, select
On as the default setting for this feature. By switching on the data
encryption, all data written to the hard disk is automatically
encrypted. Encryption prevents unauthorized access to the stored
data. When encryption is on, an encryption key must be set.
KEY POINT 1: Do not forget the encryption key! The data cannot
be restored if you forget the encryption key.
KEY POINT 2: A service representative can block changes to the
settings of this feature. For more information about settings, refer
to Service Representative Operation Limit on page 8-73.
If the optional Data Encryption feature is available for your
machine, use the following procedure for creating an encryption
key.
