uct to qualified service personnel or system
installers.
• Do not operate the unit beyond their its specified
temperature, humidity, or power source ratings.
Use the unit at temperatures between +5 °C - +45 °C
{41 °F - 113 °F} and where the humidity is between 5 % -
90 %.
The input power source for NTSC model is 120 V AC
60 Hz, for PAL model is 220 V - 240 V AC 50 Hz.
Performance and lifetime of hard disk drives are easily
affected by heat (used at high temperature) character-
istically. It is recommended to use this unit at tempera-
tures between +20 °C - +30 °C {68 °F - 86 °F}.
• POWER switch
The POWER switch is located on the rear of the unit.
Even though the POWER switch is set to "OFF", the
power supply will not be cut. To cut the power supply,
unplug the power plug of the unit 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
Before the first use, charge the built-in backup battery
(lithium battery) by turning on the power for 48 hours or
more.
If it is not charged enough, in a case where the power
goes down, the 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. (This is just an indication of
replacement. We are not providing any guarantee of the
built-in battery lifetime. Replacement cost of the built-in
battery is not covered by the warranty even if it needs
to be done within the warranty period.) Ask the shop
where you purchased the unit when replacement of the
battery is required.
• Built-in hard disk drives
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 their power on or off (for around 10 sec-
onds).
• Hard disk drives are perishable. They will need to
be replaced after 20 000 (write error will occur fre-
quently) – 30 000 hours (head and motor deteriora-
tion may occur and will reach their lifetime) of oper-
ation in case they are used at temperature of 25 °C
(77 °F).

It is recommended to keep the ambient operating
temperature below 25 °C (77 °F) to prevent data
loss from disk clashes, etc. and replace them after
around 18 000 hours (as indication) of operation.

ately. Consult your dealer for servicing.

• Do not touch the connector of the removable hard
disk by hand directly to protect the hard disk drive
from static electricity.
• Take notice of the following for the removed hard
disks.
• Do not leave them where the temperature is
high and humid. It may cause condensation.
• When they are not used for a long time, place
them where the temperature is at 0 °C (32 °F) –
30 °C (86 °F) and humidity is 20 - 40 %.
• Operate them for around an hour at least once
every six months when they are not used for a
long time.
• When placing them stacked, do not stack more
than four disks.
