Calculation of the projection distance

For a screen size different from the above, use the equation below to calculate the projection distance.

Aspect ratio 4 : 3
minimum L (m) = (diagonal screen size in inches) x 0.0304 - 0.0290
maximum L (m) = (diagonal screen size in inches) x 0.0368 - 0.0410
Aspect ratio 16 : 9
minimum L (m) = (diagonal screen size in inches) x 0.0332 - 0.0320
maximum L (m) = (diagonal screen size in inches) x 0.0401 - 0.0380

Notes on Projector Placement and Operation:

The projector uses a high-wattage lamp that becomes very hot during operation. Please observe the
following precautions.

1. Never place objects on top of the projector while it is operating.

2. Make sure there is an unobstructed space of 150 mm (5-29/32˝) or more around the projector’s
exhaust openings.
3. If the projector is placed in a box or enclosure, ensure the temperature of the air surrounding the
projector is between 0°C/32°F and 35°C/95°F. Also make sure the projector’s intake and exhaust
openings are not blocked. Take particular care to ensure that hot air from the exhaust openings is
not sucked into the intake openings.

150 mm (5-29/32˝) 150 mm (5-29/32˝) 150 mm (5-29/32˝)

or more or more or more

Direction of Air Intake and Exhaust

Intake

Exhaust

Operating the Projector Continuously

1. If the projector is to be operated continuously 10 hours or more, lamp replacement cycle duration
becomes shorter.
2. The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short
periods.
