To find the approximate distance
between the projector and screen:
Multiply the width of the screen
x 1.85 ف 1.95 (max.) ,
Multiply the width of the screen
x 2.33 ف 2.53 (min.) ,
• Refer to the chart to recom-
mended distaces in maximum
zoom and minimum zoom.
Caution:
• Placing the projector on a carpet reduces ventilation 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 8 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
• 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.
