• When using any of the PS-A's optional devices, be sure to check that device's

specifications for any special conditions or cautions that may apply to its use.

• Be aware that not only does the Hard Disk have a fixed lifetime, but that accidents

can always occur. Therefore, be sure to back up your Hard Disk's data regularly, or

prepare another Hard Disk 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

operation) or approximately 5 years, whichever comes first, at an operating

temperature of 20 °C and 333 hours of operation per month. (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 lifetime. A wet bulb temperature of 29 °C or less is

recommended. This is equivalent to the following data.
