1.3
HANDLING HARD DISK DRIVE (HDD)
The HDD is a precision device for use in reading and writing a
large amount of data on or from a disk rotating at a high speed.
If it is not handled carefully, either abnormal operation may result
or it may not be possible to read data. The HDD is sensitive to
the following items and special care is required in safeguarding
against them when handling an HDD. Also take care in handling
a set incorporating an HDD.
(1) Vibrations and impacts
(2) Static electricity
(3) Rough handling
1.3.1 HANDLING IN TRANSPORT, ETC.
• Be sure to place the HDD in the manufacturer's specified
package carton before transport.
• When receiving a package containing an HDD, check that the
package carton is not damaged (such as having holes in the
carton, crushed corners, etc.).
• Do not impact the packaging carton when loading or unloading it.
• It is not permitted to use the inner package carton only for
transporting an HDD.
• Do not stack package cartons one upon another.
Do not throw or
drop packages.
Be sure to package and
transport the HDDs correctly.
1.3.2 HANDLING AN HDD IN THE STAND-ALONE STATUS
• When handling an HDD on a hard workbench, place an
antistatic mat (rubber sheet) or similar object on the hard
surface (to prevent any impacts occurring between the HDD
and bench).
• Do not stack the HDDs one upon another.
• Do not knock an HDD with a hard object (such as a
screwdriver).
• Do not place an HDD on its side panel without using a support
(do not place an HDD in an unstable position).
1.3.3 HANDLING THE INSTALLATION OF AN HDD
• Place antistatic mats or similar sheets on all of the surfaces on
which work is conducted or when the HDD is transported.
• Do not permit the HDD to knock against the set's brackets.
• When screwing the brackets, be careful not to knock the HDD.
When using a power screwdriver, use a low-shock model and
arrange the tightening torque properly.
• When mounting an HDD in a main body, take care not to apply
excessive force to the brackets.

HANDLING LCD PANEL
1.4.1 PRECAUTIONS FOR TRANSPORTATION
When transporting the unit, pressure exerted on the internal LCD
panel due to improper handling (such as tossing and dropping)
may cause damages even when the unit is carefully packed. To
prevent accidents from occurring during transportation, pay
careful attention before delivery, such as through explaining the
handling instructions to transporters.
Ensure that the following requirements are met during
transportation, as the LCD panel of this unit is made of glass and
therefore fragile:
(1) USE A SPECIAL PACKING CASE FOR THE LCD PANEL
When transporting the LCD panel of the unit, use a special
packing case (packing materials). A special packing case
is used when a LCD panel is supplied as a service spare
part.
(2) ATTACH PROTECTION SHEET TO THE FRONT
Since the front (display part) of the panel is vulnerable,
attach the protection sheet to the front of the LCD panel
before transportation. Protection sheet is used when a LCD
panel is supplied as a service spare part.
(3) AVOID VIBRATIONS AND IMPACTS
The unit may be broken if it is toppled sideways even when
properly packed. Continuous vibration may shift the gap of
the panel, and the unit may not be able to display images
properly. Ensure that the unit is carried by at least 2
persons and pay careful attention not to exert any vibration
or impact on it.
(4) DO NOT PLACE EQUIPMENT HORIZONTALLY
Ensure that it is placed upright and not horizontally during
transportation and storage as the LCD panel is very
vulnerable to lateral impacts and may break. During
transportation, ensure that the unit is loaded along the
traveling direction of the vehicle, and avoid stacking them
on one another. For storage, ensure that they are stacked
in 2 layers or less even when placed upright.
1.4.2
OPTICAL FILTER (ON THE FRONT OF THE LCD PANEL)
(1) Avoid placing the unit under direct sunlight over a
prolonged period of time. This may cause the optical filter
to deteriorate in quality and COLOUR.
(2) Clean the filter surface by wiping it softly and lightly with a
soft and lightly fuzz cloth (such as outing flannel).
(3) Do not use solvents such as benzene or thinner to wipe the
filter surface. This may cause the filter to deteriorate in
quality or the coating on the surface to come off. When
cleaning the filter, usually use the neutral detergent diluted
with water. When cleaning the dirty filter, use water-diluted
ethanol.
(4) Since the filter surface is fragile, do not scratch or hit it with
hard materials. Be careful enough not to touch the front
surface, especially when taking the unit out of the packing
case or during transportation.
1.4.3 PRECAUTIONS FOR REPLACEMENT OF EXTERIOR
PARTS
Take note of the following when replacing exterior parts (REAR
COVER, FRONT PANEL, etc.):
(1) Do not exert pressure on the front of the LCD panel (filter
surface). It may cause irregular COLOUR.
(2) Pay careful attention not to scratch or stain the front of the
LCD panel (filter surface) with hands.
(3) When replacing exterior parts, the front (LCD panel) should
be placed facing downward. Place a mat, etc. underneath
to avoid causing scratches to the front (filter surface).
