Important Information
WARNING
1. Do not cover the lens with the supplied lens cap or
equivalent while the projector is on. Doing so can
lead to distorting or melting of the cap and burning
your hands due to the heat emitted from the light
output.
2. Do not place any objects, which are easily affected by
heat, in front of the projector lens. Doing so could
lead to the object melting from the heat that is emitted
from the light output.
The following graphic symbol is shown on the projec-
tor cabinet.
When using the projector tilted in the forward or backward
direction, use it in the range of (+15° to -15°) from horizontal.
If you tilt it outside of this range or tilt it to the left or right, it
may become damaged.
If the projector is tilted outside of this range when used tilted
in the forward or backward direction, "TiltDegreeOver" is
displayed on the LCD screen. If this message appears,
change the installation of the projector so that the angle is
within the given range from horizontal.
When installed on a floor or a desktop
CAUTION
This equipment is not suitable for use in locations where
children are likely to be present
Power Supply
1. Consult your dealer for installing the power cable to the
projector. DO NOT install the power cable by yourself.
Doing so may cause a fire or electric shock.
The projector is so designed that it operates with the
power supply voltage described below.
For C1 connection
(When the AC power to the projector power supply and
the light power supply is provided by a single cable)
• AC 200V-240V single phase 50/60Hz
For C2 connection
(When the AC power to the projector power supply
and the light power supply is provided by separate
cables)
4
• AC 100V-240V single phase 50/60Hz (projector
power supply)
• AC 200V-240V single phase 50/60Hz (light power
supply)
Ensure that your power supply fits this requirement
before attempting to use your projector.
2. The power cable is not included with the projector. Ask
your dealer for the power cable to select and purchase.
Use a power cable that meets the standards and power
supply voltage of the country where you are using the
projector.
Refer to "2-2. Connecting the Power Cable" (page 27) for
details on connecting the power cable.
3. Handle the power cable carefully. A damaged or frayed
power cable can cause electric shock or fire.
• Do not bend or tug the power cable excessively.
• Do not place the power cable under the projector, or
any heavy object.
• Do not cover the power cable with other soft materi-
als such as rugs.
• Do not heat the power cable.
• Do not change the arrangement of the installed
power cable.
4. If the projector will not be used for an extended period of
time, turn off the projector, and disconnect the power
plug from the outlet.
5. Placing the power cable and the signal cable closely to
each other can cause beat noise. If this happens, keep
the two separated so that beat noise is not generated.
Beat noise is corruption of the picture often seen as a
rolling band moving through the image.
6. Do not touch the projector during a thunder storm. Doing
so can cause electrical shock or fire.
7. When installed on the ceiling, install the breaker in a
location that is easy to reach by hand.
Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that vents
are unobstructed to prevent potentially dangerous con-
centrations of ozone and the build-up of heat inside your
projector. Allow at least 24 inches (60 cm) of space
between your projector and a wall. In particular, clear a
space of 26.7 inches (70 cm) or more in front of the air
outlet on the rear surface and 12 inches (30 cm) or more
on the upper part of the projecter body.
2. Prevent foreign objects such as paper clips and bits of
paper from falling into your projector. Do not attempt to
retrieve any objects that might fall into your projector. Do
not insert any metal objects such as a wire or screw-
driver into your projector. If something should fall into
your projector, shut down the AC power to the projector
immediately and have the object removed by a qualified
service person.
For C2 connection, turn off the projector, shut down the
AC power to the projector and the light using a circuit
breaker, and contact your dealer/distributor.
3. Turn off the projector, shut down AC power by using a
circuit breaker and contact qualified service personnel
under the following conditions. For C2 connection, turn
off the projector, shut down the AC power to the projector
and the light using a circuit breaker, and contact your
dealer/distributor for a repair.
• When the power cable or plug is damaged or frayed.
• If liquid has been spilled into the projector, or if it has
been exposed to rain or water.
