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.
When using the projector tilted in the forward or backward
direction, use it in the range of (+10° 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.
+10°
–15°
When installed on a floor or a desktop
Power Supply
1. The projector is so designed that it operates with the
power supply voltage described below.
• Projector
AC200–240V single phase 50/60Hz
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 22)
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.
4
• 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 19.7 inches (50cm) 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 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, turn off the projector, disconnect the
power plug from the outlet 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. Never remove or open the projector cabinet and never
modify the projector. Otherwise, fire, electric shock, or
leakage of laser light may cause visual impairment or
burn injuries.
6. When using a LAN cable:
For safety, do not connect to the connector for peripheral
device wiring that might have excessive Voltage.
