 Enviro nmental Specificati ons

• When using any of th e PL’ s optional devices, b e sure to check that device’s specifica-

tions for any special conditi ons or cautions that may apply to its use.

• Be aware that not only does the HDD/SSD have a fixed lifetime, but that accidents

can always occur. Therefore, be sure to back up your HDD/SSD’s data regularly, or

prepare another HDD/SSD unit that can be used for backup.

• The Hard Disk lifetime given here may be reduced due to unforeseen environmental

factors, however, generally speaking, the disk should last for 20, 000 hours (of opera-

tion) or approximately 5 years, whichever comes first at an operating temperature of

°C and 333 hours of operation per mont h. (HDD access frequency of 20% or less)

• Using the Hard Disk in an environment that is excessively hot and/or humid will

shorten the disk’s usage lif etime. A wet bulb temperature of 29

°C or less is recom-

mended. This is equivalent to the following data.

• In order to extend the lifetime of the hard disk, Pro -face recommends you set the

Windows

2000’s [C ontrol panel]-[Power Management option]-[Turn off hard disks]

selection or the Windows

XP’s [Control panel]-[Performance and Maintenance]-

[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.

• Do not vibrate t he hard disk continuously at t he same frequency. Doing so may cause

the hard disk to reduce transfer speeds or stop temporarily.
