POWER switch
The POWER switch is located at the rear of this product. Even

Built-in backup battery
• Before the first use, charge the built-in backup battery (lith-
ium 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 indi-
cation of replacement. This is just an indication of replace-
ment. 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 this product 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 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 tempera-
ture (approx. 25 °C {77 °F}).
• 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 immediate-
ly.
Contact your dealer about servicing.
When replacing the hard disk drives, take notice of the
following.
• Protect the hard disk drives from static electricity.
• Do not stack them, or keep them upright.

(Tightening torque: Approx. 0.49 N·m {5 kgf·cm})
• Avoid rapid changes of the temperature/humidity to pre-
vent condensation.
(Acceptable change: within 15 °C/h {59 °F/h})
• Recorded images on the hard disk drives may contain per-
sonal information. Please be forewarned that we don't
recover or dispose of the hard disk drives.
• Please be forewarned that any loss of information, such as
images, on the hard disk drives is not guaranteed under
