1.4 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).
