6. Optical filter (Front filter)
(1) Don't expose the optical filter directly to the sun for a long
period of time.
Exposing directly to the sun for a long period of time may
change the special property of the optical filter, resulting in a
change of color.
(2) Don't wipe the optical filter with solv ents suc h as benzene,
thinner, etc.
Wiping the optical filter with solvents suc h as benzene, thinner,
etc . may cause c hange in quality and peel off the coas ting on
the surface.
Lightly wipe the optical filter with a s oft cloth with less fluffy
(e.g. pure flannel).
Becaus e the surfac e of the optical filter is fragile, don't scrub
or hit it with a hard material.
7. Other precautions
(1) Brightnes s change in the screen
In order to save the power c onsumption, the power is
controlled (with APS function) depending on the brightnes s of
the screen. For this, the brightness may change after a short
time when the picture of the screen is changed. However, this
phenomenon is not a trouble.
(2) Component input setting
The c omponent signals 1080i and 1035i are the s ame
frequencies. So, the unit does not detect the signals
automatic ally.
In this c ase, s et required s ignal by “HD SIGNAL MODE” in the
setup menu.
8. Precaution during transportation
●
When a PDP set is delivered, the PDP body ins ide of the box
will be subject to c onstant of gravitation under the rough
handling (throwing, dropping, etc .) even though a rigid box is
us ed.
In such a case, the PDP may be damaged during
trans portation. In order to avoid an accident during
trans portation, c are must be taken to selec t a reliable carrier.
Once a reliable carrier is selected, advise them how to handle
a PDP properly during transportation. In addition, a PDP
should be insured for its physical damage before shipment.
This product is fragile because glass is widely used. Thus the
following requirements for transportation should be obs erved.
(1) Don't apply vibration and impact.
The glass of a PDP may be broken when the pac kage is
brought down on its side. When carrying the package, it must
always be handled with two persons with due c are not to apply
vibration and impact on the package.
(2) Don't lay a PDP on its side.
A PDP should always be placed upright during both
trans portation and safekeeping. Don't lay it on its side. The
panel of a PDP is very fragile to the impact in the horizontal
direction.
When a car c arries a PDP, load it on board the car in parallel
with the moving direction of the car. Don't lay s everal PDPs
one on top another.
During s afekeeping, don't lay more than two PDPs one on top
another even if they are kept upright.
9. Precaution during changing of armor parts
(rear cover, front panel and optical (front) filter)
●
Extreme care must be ex ercis ed for a PDP when the armor
parts are changed. To drop a PDP is out of question. Special
attention should be paid not to apply press ure on the glass
surfac e during the work. Don't touch the panel surface in any
way.
When changing the armor parts (rear cover, front panel and
optical (front) filter), plac e the panel (PDP side) upside down
in principle. At this time, a suitable mat must be used s o as to
prevent the front side from damaging. Howev er, exc essively
soft material (e.g. blanket) should not be us ed for this purpose
in any way. If a blanket is used, the surface of a PDP is
pressurized by the blanket when placing the panel upside
down. Under such a condition, the PDP may be broken during
the work.
