– Remove the batteries when they have been
exhausted or not in use for an extended
period of time.
– Be sure to replace both batteries at the same
time. Do not mix batteries of different types.
– Insert batteries correctly according to the “+”
and “-“ markings.
– If a fluid from a battery leaks and comes in
contact with your skin, rinse the affected skin
thoroughly as soon as possible.
– Do not place heavy objects or step on the
projector. Be especially careful that small
children do not step on the projector. If not,
the projector may drop or break, causing
injury.
– Disconnect the power cord from the power
outlet if the projector is left unused for a long
period of time. Failure to do so may result in a
fire.
– Do not bring your hands to the peripheral part
of the exhaust vent on the cabinet. This area
becomes hot during use. Be especially careful
that small children do not touch the area.
Failure to do so may result in burn.
– Do not put metal objects in front of or near
the exhaust vent. They will become hot while
projector is being used.
– Do not place the projector on top of unstable
or slanted surfaces. The projector may fall
down and cause injury.
– Do not attach the lens cover while the
projector is being used or place any objects in
front of the lens. Failure to do so may result in
a fire.
– A buildup of dust inside the projector can
cause a fire or damage. Consult your dealer
for cleaning.
– When installing the projector to a ceiling,
consult your electrician or dealer. If the
projector is not fixed securely, accidents may
result.
– Never take out the lamp soon after the
projector is used. Let the projector cool for at
least 1 hour before taking out the lamp, as
burns may result.
– If the lamp replacement icon appears or the
LAMP REPLACE indicator lights orange,
immediately replace the lamp with a new one.
Otherwise, the lamp may burst.
– If the lamp burns out, the gas or dust
(containing mercury) inside the lamp may
escape from the air vents. Immediately open
the windows and ventilate the room. If you
inhale the gas or the gas gets into your eyes
or mouth, see a doctor at once.
– Dispose of a lamp containing mercury in the
same manner as fluorescent lamps according
to local regulations.
– This projector is a precision machine. Do
not subject the projector to strong shocks or
vibrations or knock it down. Remove the lens,
close the lens mounting hole with the front
cover, and retract the adjustable feet before
placing the projector into the carrying case.
The projector may be damaged if you place it
in the case without retracting the adjustable
feet.
– Place the projector into the specified case
when transporting it by courier or any other
transportation service. Consult your dealer for
the case.
– Keep space of 1 m or more at the sides of
the projector between the intake/exhaust
vents and walls. Poor ventilation may cause
malfunction.
– Do not install the projector in the locations
with heavy dust, high humidity, oily vapors, or
cigarette smoke.
A buildup of dust on the optical elements such
as lens or mirror may degrade image quality.
– Directly touching the lens may cause poor
image quality.
– If the projector is carried from a cold place
to a warm place or the room temperature is
raised rapidly, condensation may form on the
lens and mirror due to the moisture in the
atmosphere, resulting in a blurred picture.
Wait until condensation evaporates and
normal picture is shown.
– Do not install the projector in the locations
with great difference in temperature. Doing
so may cause malfunction. The ranges of the
operating and storage temperatures are as
shown below:
Operating temperature: 41˚F–95˚F [5˚C–35˚C]
Storage temperature: 10˚F–140˚F (-10˚C-
60˚C)
– Do not install the projector near high-voltage
electric power lines or power sources.
– Do not place the projector on a carpet or bed.
The internal temperature will rise, causing
malfunction.
– To avoid increase in the internal temperature,
do not block the intake/exhaust vents.
– Position the projector at a proper angle.
Incorrect positioning may cause troubles and
accidents. Do not roll the projector more than
20 degrees from the horizontal.
– Do not place any heat-sensitive objects on the
projector.
