BEFORE USE

Notes on handling internal hard disk
drive components
This unit uses an internal hard disk drive (HDD).
Be sure to observe the following points carefully when
operating, setting-up and servicing the unit.
Conditions to avoid
The hard disk is sensitive to dust, vibrations and shocks,
and should also not be used near magnetic objects. To
prevent loss of recorded data, observe the following
precautions:
Do not subject the digital video recorder to shocks.
Do not use the digital video recorder on a vibrating or
unstable surface.
Do not disconnect the power plug from the wall outlet
during recording or playback.
Do not use the digital video recorder in areas of extreme
temperature changes (10ºC or more per hour).
Condensation may occur if the digital video recorder is
moved to an area of extremely different temperature or
high humidity. If the unit is operated when condensation
has formed, it may cause operating problems. If sudden
changes in the ambient temperature occur, wait for the
temperature to stablize before operating the unit.
Do not install the digital video recorder in areas of
constant vibration such as motor vehicles or trains.
The digital video recorder has ventilation holes. Make
sure these holes are not blocked after installation.
Do not use the digital video recorder in areas with poor
ventilation, such as a bookshelf or box.
The digital video recorder is designed to be placed
horizontally. Do not place it in an upright position.
When installing the digital video recorder in a rack,
ensure a gap of at least 5 cm at the top and bottom.
When placing the unit down on a surface such as a floor,
attach the feet to the base of the unit and place it down
gently. If the feet are not attached, place the unit down
very carefully.
Do not move the unit for 30 seconds after
disconnecting the power.
After the power is disconnected, the disk inside the HDD
will continue to spin for a brief period due to inertia, and the
heads will be in an unstable state. During this time, the unit
is even more susceptible to shocks and vibration than when
power is being supplied. Make sure that the unit is not
subjected to even gentle vibration for at least 30 seconds
after disconnecting the power.
Notes on transporting
When transporting the unit, pack it securely using the
packing materials. In addition, use a method of
transportation that minimizes vibration.
Notes when replacing the HDD
Be sure to follow the correct replacement procedure when
replacing the HDD.
HDDs that have been removed from their packing may
not operate correctly if they are subjected to any shocks
and vibration. It is recommended that you place HDD
onto a soft, level surface with the printed circuit board
facing upward after unpacking it.
Be careful not to subject the HDD to shocks or vibration
when removing and tightening screws as part of the
HDD replacement procedure. Make sure that all screws
are tightened securely so that they will not become
loose. The HDD is sensitive to static electricity, so you
should take proper precautions to prevent static
electricity buildup.
Handling the HDD unit by itself
If transporting or storing the HDD unit by itself, always be
sure to pack it in the packing first. In addition, use a method
of transportation that minimizes the vibration.
If the HDD becomes damaged, handle the unit and the
damaged HDD that has been removed in order for it to be
replaced carefully to prevent the problem from being
aggravated until as the nature of the problem can be
checked and analyzed.
The hard disk and cooling fan are
consumable items.
Under use in an ambient temperature of 25ºC, the hard disk
should generally be replaced after 2 years, and the cooling
fan after 3 years. These figures are intended as guidelines
only, and are not guarantees of part performance.
The POWER indicator flashes if a problem occurs in the
hard disk or fan. ( P.11)
For important recordings
Always make a test recording beforehand to check that
the digital video recorder's playback is normal.
Note that no compensation will be provided for losses
due to recording or playback problems arising from
problems with the digital video recorder or its connected
devices during operation.
To be prepared for malfunctions or accidents, back up
important recordings periodically, or record using
mirroring.
Hard disk protection
The hard disk is checked automatically at power ON. If a
hard disk problem is found, the POWER indicator flashes.
To initialize the disk or save images stored on the disk,
contact a Sanyo service center.
