Notes on use
In order to get the best picture quality
Draw curtains or blinds over any windows and turn off any lights near th\
e
screen to prevent outside light or light from indoor lamps from shining \
onto
the screen.
Do not touch the surfaces of the lens with your bare hands.
If the surface of the lens becomes dirty from fingerprints or anything e\
lse, this
will be magnified and projected onto the screen.
Screen
Do not apply any volatile substances which may cause discoloration to th\
e
screen, and do not let it become dirty or damaged.
Lamp
The lamp may need to be replaced earlier due to variables such as indivi\
dual
lamp characteristics, usage conditions and the installation environment,\
especially when the projector is subjected to continuous use for more th\
an
10 hours or the power is frequently turned on and off.
Liquid crystal panel
The liquid crystal panel of the projector is built with very high precis\
ion
technology to provide fine picture details. Occasionally, a few non-acti\
ve
pixels may appear on the screen as fixed points of blue, green or red.
Please note that this does not affect the performance of your LCD.
