in temperature.
Avoid using volatile liquids
Do not use volatile liquids, such as insecticide or some types of cleaner, near the projector. Do not leave rubber
or plastic products touching the projector for a long time. They will leave marks on the finish. When cleaning,
be sure to follow the cleaning product’s safety instructions.
