Preparation
About the screen
If the screen you are using is dirty, damaged or discolored, attractive
projections cannot be obtained. Do not apply any volatile substances to the
screen, and do not let it become dirty or damaged.
About the lamp
The lamp may need to be replaced earlier due to variables such as a
particular lamp’s characteristics, usage conditions and the installation
environment, especially when it is subjected to a continuous use for more
than 10 hours.
About the SD memory card (PT-L780NTU only)
Static electricity from the human body can damage the SD memory card. To
prevent this, you should touch a nearby metallic object such as an aluminium
sash or a door knob to dissipate the static charge from your body.
About the card slot (PT-L780NTU only)
Make sure that there are no foreign objects inside the slot when inserting the
SD memory card or an optional wireless card. Failure to observe it may
damage the card and the slot.
Before carrying out cleaning and maintenance, be
sure to disconnect the power cord plug from the
wall outlet.
Wipe the cabinet with a soft, dry cloth.
If the cabinet is particularly dirty, soak the cloth in water with a small amount
of neutral detergent in it, squeeze the cloth very well, and then wipe the
cabinet. After cleaning, wipe the cabinet dry with a dry cloth.
If using a chemically-treated cloth, read the instructions supplied with
the cloth before use.
Do not wipe the lens with a cloth that is dusty or which produces lint.
If any dust or lint gets onto the lens, such dust or lint will be magnified and
projected onto the screen. Use a blower to clean any dust and lint from the
lens surface, or use a soft cloth to wipe off any dust or lint.
