IMPORTANT SAFEGUARDS
Be sure to read the following safeguards when setting up
your projector.
Caution concerning the lamp unit

Potential hazard of glass particles if
lamp ruptures. In case of lamp rupture,
contact your nearest Sharp Authorized
Projector Dealer or Service Center for
a replacement.
See “Replacing the Lamp” on page 57.
Caution concerning the setup of the projector

For minimal servicing and to maintain high image qual-
ity, SHARP recommends that this projector be installed
in an area free from humidity, dust and cigarette smoke.
When the projector is subjected to these environments,
the lens must be cleaned more often. As long as the
projector is regularly cleaned, use in these environ-
ments will not reduce the overall operation life of the
unit. Internal cleaning should only be performed  by a
Sharp Authorized Projector Dealer or Service Center.
Do not set up the projector in places exposed to
direct sunlight or bright light.

Position the screen so that it is not in direct sunlight or
room light. Light falling directly on the screen washes
out the colors, making viewing difficult. Close the cur-
tains and dim the lights when setting up the screen in a
sunny or bright room.
The projector may be safely tilted to a maximum
angle of 12 degrees.

Placement should be within ±12 degrees of horizontal.
Do not subject the projector to hard impact and/
or vibration.

Take care with the lens so as not to hit or damage the
surface of the lens.
Rest your eyes occasionally.

Continuously watching the screen for long hours will
cause eye strain. Be sure to occasionally rest your eyes.
Avoid locations with extremes of temperature.

The operating temperature of the projector is from 41°F
to 95°F (+5°C to +35°C).

The storage temperature of the projector is from
–4°F to 140°F (–20°C to +60°C).
Do not block the exhaust and intake vents.

Allow at least 7 7/8 inches (20 cm) of space between
the exhaust vent and the nearest wall or obstruction.
Be sure that the intake vent and the exhaust vent are
not obstructed.

If the cooling fan becomes obstructed, a protection cir-
cuit will automatically put the projector into the standby
mode. This does not indicate a malfunction. Remove
the projector power cord from the wall outlet and wait
at least 10 minutes. Place the projector where the intake
and exhaust vents are not blocked, plug the power cord
back in and turn on the projector. This will return the
projector to the normal operating condition.
Caution regarding transportation of the projec-
tor

When transporting the projector, be sure not to subject
it to hard impact and/or vibration, as this can result in
damage. Take extra care with the lens. Before moving
the projector, be sure to unplug the power cord from
the wall outlet, and disconnect any other cables con-
nected to it.
Other connected equipment

When connecting a computer or other audio-visual
equipment to the projector, make the connections AF-
TER unplugging the power cord of the projector from
the AC outlet and turning off the equipment to be con-
nected.

Please read the operation manuals of the projector and
the equipment to be connected for instructions on how
to make the connections.
Using the projector in other countries

The power supply voltage and the shape of the plug
may vary depending on the region or country you are
using the projector in. When using the projector over-
seas, be sure to use an appropriate power cord for the
country you are in.
Temperature monitor function

If the projector starts to overheat
due to setup problems or block-
age of the air vents, “
” and
“” will illuminate in the lower left corner of the
picture. If the temperature continues to rise, the lamp
will turn off, the temperature warning indicator on the
projector will blink, and after a 90-second cooling-off
period the projector will enter the standby mode. Refer
to “Maintenance Indicators” on page 55 for details.
Info
•The cooling fan regulates the internal temperature, and
its performance is automatically controlled. The sound
of the fan may change during projector operation due
to changes in the fan speed. This does not indicate
malfunction.
•Do not unplug the power cord during projection or cool-
ing fan operation. This can cause damage due to rise
in internal temperature, as the cooling fan also stops.

Using the Remote Control
Inserting the Batteries
The batteries (two R-6 batteries (“AA” size, UM/
SUM-3, HP-7 or similar)) are supplied in the
package.
1Press the  mark on the cover
and slide it in the direction of the
arrow.
2Insert the batteries.
•Insert the batteries making sure the po-
larities correctly match the 
 and 
marks inside the battery compartment.
3Attach the cover and slide it un-
til it clicks into place.
Incorrect use of the batteries may cause them to leak or explode. Please follow the precautions below.
 Caution
•Insert the batteries making sure the polarities correctly match the  and  marks inside the battery compart-
ment.
•Batteries of different types have different properties, therefore do not mix batteries of different types.
•Do not mix new and old batteries.
This may shorten the life of new batteries or may cause old batteries to leak.
•Remove the batteries from the remote control once they have run out, as leaving them in can cause them to leak.
Battery fluid from leaked batteries is harmful to skin, therefore be sure to first wipe them and then remove them
using a cloth.
•The batteries included with this projector may run down in a short period, depending on how they are kept. Be
sure to replace them as soon as possible with new batteries.
•Remove the batteries from the remote control if you will not be using the remote control for a long time.
Usable Range

The remote control can be used to control
the projector within the ranges shown in
the illustration.
Note
•The signal from the remote control can be re-
flected off a screen for easy operation. How-
ever, the effective distance of the signal may
differ depending on the screen material.
When using the remote control:
•Be sure not to drop, expose to moisture or high
temperature.
•The remote control may malfunction under a
fluorescent lamp. In this case, move the pro-
jector away from the fluorescent lamp.
