Under no circumstances should you ever undo or remove any
other covers. Refer servicing only to suitably qualified professional
service personnel.
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.
