* This distance is especially recommended for ceiling-mounted use and other
permanent installations.
NOTE:
Values shown are approximate.
The value for L (distance to screen)
varies slightly depending on the zoom
lens characteristics.
When the shortest projection distance is
used, a small amount of distortion may
occur in the image due to the zoom lens
characteristics.
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 0.0292 – 0.036
maximum
L (m) = (diagonal screen size in inches) x 0.0351 – 0.044
NOTE: Distances calculated with the above equations will include a slight error.
Installable Angle
Install the projector at an angle within the range shown below.
• Vertical direction
The projector may not be angled horizontally.
+30°
• Vertical direction
The projector
may be installed
at a vertical
angle of ±30°.

1. The “i” appearing after the resolution indicates an interlaced signal.
2. The following symbols are used to indicate picture quality.
AA Maximum picture quality can be obtained.
A
Signals are converted by the image processing circuit before picture is projected.
B
Signals are compressed by the image processing circuit before picture is projected.
3. When 750 (720)/60p or 750 (720)/50p signals are input to a computer input terminal, images are projected in the WIDE750 (720) format. Be sure
to run the auto setup function.

CAUTION
It may not be possible to send or receive commands for about 10 to 60 seconds when the lamp is first turned on. If this occurs, wait for 60 seconds, then
try sending or receiving again. When sending multiple commands, be sure to wait for at least 0.5 second after receiving a response from the projector
before sending the next command. Additional time is sometimes required for response due to processing inside the projector. Set the time-out period for
command response to 10 seconds or more.
NOTE:
If a wrong command is received, the projector will send an ER401 command to the computer.
When sending commands without parameters, a colon (:) is not necessary.

Do not send PON, POF, or OSH commands continuously in a short period of time. Doing so may burst the lamp or shorten the lamp replacement cycle.
When a command other than OSH is sent while the shutter function is operating, the projector will send an ER401 command in reply and release the shutter function.

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.
200 mm (7-7/8˝) or more

The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short
periods (one hour or less).
