Precautions
Power source
The input power source for this product is 100 V AC to 240 V AC, 50 Hz/60 Hz. Do not connect to the outlet
that provides the power to equipments that requires a measurable amount of power (such as a copy machine,
air conditioner, etc.). Avoid placing this product in locations where is subject to water.
Ambient operating temperature
Use this product at temperatures between +5 °C to +40 °C. Failure to do so may damage the internal parts or
cause malfunction. Performance and lifetime of hard disk drives are easily affected by heat (used at high
temperature). It is recommended to use this product at temperatures between +20 °C to +30 °C.
Power cable
Connect the power cable firmly. Align the connected power cable not to be pulled/stressed. To cut the power
supply, unplug the power plug of this product from the AC outlet. When using the power supply control unit,
turn off the power of the power supply control unit.
Built-in backup battery
• Built-in backup battery is consumed when the power supply is shut down from the AC outlet. In this case, internal
clock may keep bad time or the operative condition may be different to that before the electric power failure.
• The built-in battery life is approximately 5 years as an indication of replacement. (The built-in battery life may
become shorter depending on the use condition.)Replace the built-in battery after 5 years of use. ("5 years of use"
is just an indication of replacement. We are not providing any guarantee of the built-in battery lifetime.)When the
built-in battery life runs out, some settings such as the time and date setting will not be saved once the power is
turned off.
• Ask your dealer when replacement of the battery is required.
Hard disk drive (HDD)
• Hard disk drives are vulnerable to vibration. Handle them with care. It is possible to damage them if they are moved
while their motors are still running.
• Do not move them just after turning the power off (for around 30 seconds).
• The lifetime of hard disk drives is limited by use. Write errors may occur frequently after around 20 000 hours of
operation, and the head and motor deterioration may occur after around 30 000 hours of operation. They will reach
the end of their lifetime after 30 000 hours of operation if they have been used at the recommended ambient
temperature (approx. +25 °C).
• It is recommended to replace them after around 18 000 hours of operation to prevent data loss from disk failures.
• When hard disk drive trouble occurs, replace it immediately.
Contact your dealer about servicing.
