6. Optical filter (Front filter)
(1) Don't expose the optical filter directly to the sun for a long
period of time.
Exposing directly t o the sun f or a lo ng period of time may
change the special property of the optica l filter, resulting in a
change of colour.
(2) Don't wipe the op tical f ilter with solvents suc h as benze ne,
thinner, etc.
Wiping the optica l f ilt er with solvents suc h as benzene, thinner,
etc . may cause c hange in quality and peel off the coas ting o n
the surface.
Lightly wipe the o ptical filter with a soft cloth with less f lu ffy
(e.g. pure flannel).
Becaus e the surface of the optical filter is fragile, don't scrub
or hit it with a hard material.
7. Other precautions
(1) Bright ness change in the screen
In ord er t o save the p ower consumption, the power is
controlled (with APS function) depending on the brightness
of t he s creen. For this, the brightness may ch ange after a
short time when the picture of the screen is ch anged.
However, this phenomenon is not a trouble.
(2) Component input setting
The comp onent signals 1080i and 1035i are the same
frequencies. So, t he unit does not d etec t t he signals
automat ically.
In this cas e, set required signal by HD SIGNAL MODE in
the setup menu.
8. Precaution during transportation
7 When a PDP set is delivered, th e PDP body inside of the box
will be subject to c onstant of gravitatio n under the rough
handling (throwing, dropping, etc .) even though a rigid box is
used.
In such a case, the P DP may be damaged du ring
trans portation. In order t o avoid an accident durin g
trans portation, care must be t aken to selec t a reliable carrier.
Once a reliable carrier is selected, advise the m how to h andle
a PDP properly d uring transportat io n. In addition, a PDP
should be insured for its physical damage before shipment.
This product is fragile because glass is widely used. Thus th e
following requirements for transportation should be observed.
(1) Don't apply vibration and impact.
The glass of a PDP may be bro ken when the pac kage is
brought down on its side. When carryin g th e package, it must
always be handled wit h 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 p laced u pright during both
trans portation and saf ekeeping. Don't lay it on its sid e. Th e
panel of a PDP is very fragile t o t he impa ct in the horizontal
direction.
When a car carries a PDP, load it on boa rd the car in para llel
wit h the moving d irection of the car. Don't lay s everal P DPs
one on t op another.
During s afekeeping, don't lay more than two P DP s 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)
7
Extreme care must be exercised for a PDP when the armor
parts are ch anged. To drop a PDP is out of question. Special
att ention should be p aid not to apply pressure on the glass
surfac e during the work. Don't touch the p anel surface in any
way.
When changing t he armor part s (rear cove r, front panel and
optical (front) filter), place the panel (PDP side) upside d own
in principle. At this time , a suitable mat must be used so as to
prevent the front side from d amaging. However, exc essively
soft material (e.g. blanket) sh ould not be us ed for this purpose
in any way. If a blanket is used, the su rface of a PDP is
pressurized b y the blanket when placing the panel upside
down. Under such a condition, the PDP may be broken during
the work.
