Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that
vents are unobstructed to prevent potentially dan-
gerous concentrations of ozone and the build-up of
heat inside your projector. Allow at least 23.6 inches
(60 cm) 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
11.8 inches (30 cm) or more on the upper part of the
projecter body. (→ page xi)
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 projec-
tor. Do not insert any metal objects such as a wire or
screwdriver 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.
• 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 per-
formance, indicating a need for service.
4. When using a LAN cable:
For safety, do not connect to the connector for periph-
eral device wiring that might have excessive Voltage.
5. Make sure to mount the power cable stopper before
attempting to use your projector. Refer to page
about the power cable stopper.
Cleaning
1. Shut down AC power by using a circuit breaker before
cleaning.
For C2 connection, turn off the projector, shut down
the AC power to the projector and the light using a
circuit breaker.
2. Clean the cabinet periodically with a cloth. If heavily
soiled, use a mild detergent. Never use strong deter-
gents or solvents such as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be
careful not to scratch or mar the lens.
4. Do not handle the projector and the power cable with
wet hands. Doing so can cause electrical shock or fire.
5. Do not use a spray containing flammable gas to
remove dust attached to the lens and cabinet. Doing
so may result in fires.

the Laser is turned on and while the POWER
indicator is blinking green. Doing so could cause
premature Laser failure.
3. Keep hands away from the lens mounting portion
while the lens shift is in operation. Failure to do so
could result in fingers being pinched between the
cabinet and lens cover.
