• The environment specifications given here are for a PSA-HD20
installed in a PS-A unit.
• Pro-face does not guarantee the preservation of any data stored on
the PSA-HD20 if the HDD unit has an accident, malfunctions or is
damaged in any way. Therefore, the regular backing up of important
HDD data to either a floppy disk, or other type of suitable magnetic
media is strongly recommended.
• The PSA-HD20 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 PSA-HD20 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 recommends
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 recommended.
