• Please consult your dealer for more 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.
Do not tilt the projector forward or back at a greater angle
than 15°. Doing so may result in malfunction. When mount-
ing the projector on the ceiling, select an appropriate option
for [Fan Tilt Setting].

Power Supply
1. The projector is so designed that it operates with the
power supply voltage described below.
• AC100–130V 10.3 to 7.9 A 50/60Hz Single-phase
• AC200–240V 5.1 to 4.3 A 50/60Hz Single-phase
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 17) 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.
4. 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.
5. Do not touch the projector during a thunder storm. Doing
so can cause electrical shock or fire.
6. 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 12 inches (30cm) of space
between your projector and a wall. In particular, clear a
space of 27.6 inches (70 cm) or more in front of the air
outlet on the rear surface and 19.8 inches (50 cm) or
more in front of the air outlet on the lamp side.
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, disconnect it immediately and have the
object removed by a qualified service person.
3. Turn off the projector, unplug the power cable and have
the projector serviced by a qualified service personnel
under the following conditions:
• 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.
• If the projector does not operate normally when you
follow the instructions described in this user's
manual.
• If the projector has been dropped or the cabinet has
been damaged.
• If the projector exhibits a distinct change in perfor-
mance, indicating a need for service.
4. Keep any items such as magnifying glass out of the light
path of the projector. The light being projected from the
lens is extensive, therefore any kind of abnormal objects
that can redirect light coming out of the lens, can cause
unpredictable outcome such as fire or injury to the eyes.
5. When using a LAN cable:
For safety, do not connect to the connector for peripheral
device wiring that might have excessive Voltage.
6. Do not look into the lens while the projector is on. Serious
damage to your eyes could result.
7. Do not try to touch the air outlets on the projector during
normal projector operation as it is hot.
