-8-
• The environment specifications given here are for a unit installed in
a PS-B.
• Pro-face does not guarantee the preservation of any data stored on
the HDD unit if the HDD unit has an accident, malfunctions or is
damaged in any way. Therefore, the regular backing up of important
HDD unit data to either a floppy disk, or other type of suitable mag-
netic media is strongly recommended.
• This HDD unit has a finite usage lifetime. The lifetime figure given in
this document is for reference, and the periodic replacement of the
current HDD unit with a new HDD unit is strongly advised.
• Using the HDD unit in an environment that is excessively hot and/or
humid will shorten the disk’s usage lifetime. A wet bulb temperature
of 29
o
C or less is recommended. This is equivalent to the following
data.
• In order to extend the lifetime of the hard disk, Pro-face recom-
mends you set the Windows
®
[Control panel]-[Power Management
option]-[Turn off hard disks] selection to turn the hard disk off when
the unit is not being operated. A setting of 5 minutes is recom-
mended.
