Observe 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 replacement.
See “Regarding the Lamp” 
on page 56.
Caution concerning the setup of the 
projector
For minimal servicing and to maintain high 
image quality, 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 vents and lens must be 
cleaned more often. As long as the 
projector is regularly cleaned, use in these 
environments 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. 
Rest your eyes occasionally.
Continuously watching the screen for long 
hours will cause eye strain. Take regular 
breaks to rest your eyes.
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 diffi  cult. Close the curtains 
and dim the lights when setting up the 
screen in a sunny or bright room.
Caution regarding placing of the projector
Place the projector on a level site within the 
adjustment range (9 degrees) of the 
adjustment foot.
After the projector is purchased, a faint 
smell from the vent may appear when the 
power is fi  rst turned on. This is normal and 
is not a malfunction. It will disappear after 
the projector is used for a while.
■
■
■
■
■
■
When using the projector in high-
altitude areas such as mountains (at 
altitudes of approximately 1,500 
meters (4,900 feet) or more)
When you use the projector in high-altitude 
areas with thin air, set “Fan Mode” to 
“High”. Neglecting this can affect the 
longevity of the optical system.
Use the projector at altitudes of 2,300 
meters (7,500 feet) or less.
Warning about placing the projector in 
a high position
When placing the projector in a high 
position, make certain it is carefully secure 
to avoid personal injury caused by the 
projector falling down.
Do not subject the projector to hard 
impact and/or vibration.
Protect the lens so as not to hit or damage 
the surface of the lens.
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 11 13/16 inches (30 cm) of 
space between the exhaust vent and the 
nearest wall or obstruction.
Ensure that the intake vent and the exhaust 
vent are not obstructed.
If the cooling fan becomes obstructed, a 
protection circuit will automatically put the 
projector into Standby mode to prevent 
overheat damage. This does not indicate a 
malfunction. (See pages 54  and 55.) 
R

emove 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.

IntroductionCaution regarding usage of the projector
If you are not to use the projector for a long 
time or before moving the projector, make 
certain you unplug the power cord from the 
wall outlet, and disconnect any other 
cables connected to it.
Do not carry the projector by holding the 
lens.
When storing the projector, ensure that you 
close the lens shutter.
Do not expose the projector to direct 
sunlight or place next to heat sources. 
Doing so may affect the cabinet color or 
cause deformation of the plastic cover.
Other connected equipment
When connecting a computer or other 
audio-visual equipment to the projector, 
make the connections AFTER unplugging 
the power cord of the projector from the 
AC outlet and turning off the equipment to 
be connected.
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 overseas, make 
sure you use an appropriate power cord for 
the country you are in.
Temperature monitor function
If the temperature inside the projector 
increases, due to blockage of the air vents, 
or the setting location, the temperature 
warning indicator will blink. And if the 
temperature keeps on rising, “
” will 
illuminate in the lower left corner of the 
picture with the temperature warning 
indicator blinking. If this state continues, 
the lamp will turn off, the cooling fan will 
run and then the projector will enter 
Standby mode. Refer to “Maintenance 
Indicators” on pages 54  and 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.

IntroductionInserting the Batteries
1  Pull down the tab on the cover and remove the cover towards the direction of the arrow.
2 Insert the batteries.Insert the batteries making sure the polarities correctly match 
the  m and n marks inside the battery compartment.
3  Insert the lower tab of the cover into the opening, 
and lower the cover until it clicks in place.
Incorrect use of the batteries may cause them to leak or explode. 
Please follow the precautions below
Caution
Danger of explosion if battery is incorrectly replaced.
Replace only with alkaline or manganese batteries.
Insert the batteries making sure the polarities correctly match the m and n marks inside the batter y 
compartment.
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  uid from leaked batteries is harmful to skin, therefore ensure you wipe them  rst 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.
Comply with the rules (ordinance) of each local government when disposing of worn-out batteries.

Usable Range
The remote control can be used to control the 
projector within the ranges shown in the 
illustration.
The signal from the remote control can be 
re ected off a screen for easy operation. 
However, the effective distance of the signal 
may differ depending on the screen material.

Note
When using the remote controlEnsure that you do not drop it or expose it to 
moisture or high temperature.
The remote control may malfunction under a 
 uorescent lamp. In this case, move the 
projector away from the  uorescent lamp.
