BEFORE USE
Notes on handling the internal HDD
This digital video recorder uses an internal HDD.
Be sure to observe the following points carefully when
operating, setting-up, or servicing the digital video recorder.
„ Do not subject the digital video recorder to
sudden impact or vibration.
If the digital video recorder is subjected to sudden impact or
vibration, it may damage the hard disk or cause corruption of
the data stored within it.
z
Do not move the digital video recorder while the power is
turned on. Always ensure that the power is turned off
before removing the digital video recorder from or placing it
in a rack.
z When transporting the digital video recorder, pack it
securely using the specified materials. In addition, choose
a method of transportation that minimizes vibration.
z When placing the digital video recorder on the floor or
another similar surface, attach the specified pads to its
base and place it down gently.
„ Do not move the digital video recorder for 30
seconds after turning off the power.
After the power is turned off, the disk inside the HDD
continues to spin for a brief period due to inertia and the
heads are in an unstable condition.
During this period, the digital video recorder is even more
susceptible to damage from sudden impact and vibration than
when it is turned on. Make sure that the digital video recorder
is not subjected to even gentle vibration for at least 30
seconds after turning off the power.
„ Do not operate the digital video recorder when
condensation has formed on it.
If the digital video recorder is operated in this type of
condition, there is a possibility that it may become
permanently damaged.
If the temperature around the digital video recorder changes
suddenly, wait for it to stabilize before operating the digital
video recorder.
„ Notes on replacing the HDD
Be sure to follow the correct procedure when replacing the
HDD.
z
HDDs that have been removed from their packing may not
operate correctly if they are subjected to sudden impact or
vibration. It is recommended that you place the HDD on a
soft, level surface with the printed circuit board facing
upward after it has been unpacked.
z Take care to avoid subjecting the HDD to sudden impact or
vibration when removing and tightening screws as part of
the HDD replacement procedure.
Tighten all screws securely to ensure that they do not
loosen.
z The HDD is sensitive to static electricity; accordingly, you
should take the appropriate precautions to prevent the
buildup of static charges.
„ Handling a detached HDD unit
If transporting or storing the HDD unit in a detached condition,
be sure to first of all pack it using the specified materials.
In addition, choose a method of transportation that minimizes
vibration.
Notes on installation locations
Avoid subjecting the HDD to sudden impact or vibration. In
addition, avoid using it in dusty locations or near magnetic
objects. The following precautions should be observed in
order to prevent the loss of recorded data:
z
Do not subject the digital video recorder to sudden impact.
z Do not use the digital video recorder on a vibrating or
unstable surface.
z Do not disconnect the power plug from the wall outlet
during recording or playback.
z Do not use the digital video recorder in areas with extreme
temperature changes (i.e., 10ºC or more per hour).
z Condensation may occur if the digital video recorder is
moved to an area with a significantly different temperature
or high humidity. If the digital video recorder is used with
condensation inside, operating problems may occur.
z Do not install the digital video recorder inside motor
vehicles, trains, or other areas with constant vibration.
z The digital video recorder has ventilation holes on its left,
rear, and bottom panels. Ensure that these holes are not
blocked after installation.
z Do not use the digital video recorder in a bookshelf, box, or
any other area with poor ventilation.
z This digital video recorder is designed for use in a
horizontal orientation, and vertical setup may result in
malfunction.
z When installing the digital video recorder in a rack, ensure
that a gap of at least 5 cm at the back and sides and 1 cm
at the top and bottom is provided.
Notes on handling the hard disk drive
„ Replacement time of worn or deteriorated
components
A hard disk is a component that wears out or deteriorates from
use; its service life depends on usage environment. If used at
a temperature of 25°C, for example, it becomes prone to
writing errors when it has run beyond two years in total in
power feeding use. If used further, it may come to the end of
service life due to the deterioration of the head and/or motor.
For worry-free way to make use of a hard disk drive, it is
recommended as a general rule of thumb to use one at an
ambient temperature of 25°C and replace it with new one in
every two years.
(This replacement time span, however, is just a rough guide
and does not warrant the service life.)
„ Hard disk service life
As a hard disk is precision mechanical equipment, handle it
with care to avoid a physical shock.
z
Shock or vibration may cause a hard disk to malfunction.
z Do not move or install a hard disk immediately after turning
it on or off, i.e. for approximately 30 seconds, because it
still runs under unstable condition.
z Do not block the ventilation holes or stop the cooling fan.
Temperature rise in heat inside may shorten the service life
of the hard disk drive.
