Precautions For Use And Maintenance - Toshiba P503DL Service Manual

PRECAUTIONS FOR USE AND MAINTENANCE

Request to User
Plastic Screen
The P503DL screen is made of a plastic material and can be easily scratched. During manufacture and
packing, every care is taken to ensure that no hard objects that could scratch or otherwise cause damage are
allowed to touch the screen when opening the carton box and taking out the product. Please exercise
caution, when unpacking the unit to prevent the packing material or other items from scratching and
rubbing the screen to avoid (i) damage to the screen and (ii) generation of static electricity which may attract
dust particles onto the screen.
Precautions on Use
Connection of a grounded cable
Ground the projection unit in order to prevent electric shock with 3-core power cable. There is greater danger
of electric shock when multi projection units are used without ground wire connected.
Condensation
When room temperature rises rapidly (or the Data Display projection unit is moved from a cold place to a
hot place), condensation may form on the lens, causing picture distortion or color fade-out. In such case, wait
for a while (with keeping power ON) until the condensation clears.
About cooling fan and color wheel motor
The axial cooling fan and also color wheel motor in the projection unit should be considered a consumable
item and need to be replaced after about one or two years of use or whenever noise or other symptoms of
breakdown are apparent.
** Air filter equipped at air intake needs periodical cleaning. A clogged air filter will result in temperature
build up inside the P503DL cabinet. Possibly in excess of stated operating specification, this may lead to
malfunction or reduced equipment life.
Maintenance
Do not use solvent or paint thinner
If these are used, coating layer may peel off or deteriorate. If rubber or plastic comes into contact with the
projection unit for a long time, the projection unit may be stained.
Care of the screen
After switching the power supply off, gently wipe the screen with a soft cotton cloth. Since the screen
surface is easily scratched, this may also build up an electronic static charge. Do not rub it with a hard
object; the screen may be easily damaged. Never use a chemical duster.
Care of the cabinet
After switching the power supply off, wipe gently with soft cloth.
When using a chemical duster, follow the maker's precautions.
Care of the air filter
The air intake filter should be regarded as a consumable and changed on periodic bases, depending on the
operating conditions. If or when the filter becomes clogged (by oily smoke etc) replacement of the filter is
recommended.
For a temporally remedy, the filte r may be cleaned by an oil removal cleaner, detergent used in a kitchen
or a diluted vinegar solution.
Contact your dealer for the replacement work.
