Caution:
• Placing the projector on a carpet reduces ventila-
tion from the fan on the bottom and might cause
problems. Place a hard board or similar item
under the projector to facilitate ventilation of the
unit.
• Place the projector more than 20 in. from the wall
to prevent blocking the intake, exhaust slots and
ventilation of this projector because hot air comes
out of it.
• Do not use the projector under the following
circumstances, which may cause fire or electric
shock.
• in a dusty or humid place
• while the projector is lying sideways or upside
down.
• near a heater
• in a kitchen or oily, smoky or damp place
• in direct sunlight
• with high temperature, such as the closed car
• where the temperature is lower than 41°F or
higher than 95°F
Important:
• Do not put stress on the lens or focus ring, as this
may damage them.
• Keep your room dark while using the projector. The
image cannot be seen clearly in a bright place.
