11. Do not attempt to disassemble this projector. There are dangerous
high voltages inside which may cause death if you should come into
contact with live parts.
Under no circumstances should you ever undo or remove any other
covers. Refer servicing only to suitably qualified professional service
personnel.
Warning
• Please keep the original packing for possible future shipment.
• If you need to pack your projector after use, adjust the projection lens to an appropriate position,
put the lens cushion around the lens, and fit the lens cushion and projector cushion together to
prevent damage during transportation.
12. When you think service or repair is required, take the projector only
to a suitably qualified technician.
Moisture condensation
Never operate the projector immediately after moving it from a cold
location to a hot location. When the projector is exposed to such a change
in temperature, moisture may condense on the crucial internal parts. To
prevent the projector from possible damage, do not use the projector for at
least 2 hours when there is a sudden change in temperature.
Avoid volatile liquids
Do not use volatile liquids, such as insecticide or certain types of cleaner,
near the projector. Do not have rubber or plastic products touching the
projector for a long time. They will leave marks on the finish. If cleaning
with a chemically treated cloth, be sure to follow the cleaning product's
safety instructions.
