the lamp housing. Contact your dealer for cleaning or 
inspecting the projector, or replacing the lamp.
  WARNING 
						

							7
–  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.
  CAUTION
–   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. 
  CAUTION
–   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. Other wise, 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–104˚F (5˚C–40˚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 10 degrees from the 
horizontal.
– Do not place any heat-sensitive objects on the  projector. 
Precaution During Use
Safety Instructions 
						

							8
Openings in the cabinet are provided for ventilation. 
To ensure reliable operation of the product and to 
protect it from overheating, these openings must not 
be blocked or covered. 
 CAUTION
Hot air is exhausted from the exhaust vent. When 
using or installing the projector, the following 
precautions should be taken. 
– Do not put any flammable object or spray can near 
the projector, hot air is exhausted from the air 
vents.
–  Keep the exhaust vent at least 3’ (1 m) away from 
any objects.
–  Do not touch peripheral parts of the exhaust vent, 
especially screws and metallic parts. These areas 
will become hot while the projector is being used.
–  Do not put anything on the cabinet. Objects put on 
the cabinet will not only get damaged but also may 
cause fire hazard by heat.
Cooling fans are provided to cool down the projector. 
The fans’ running speed is changed according to the 
temperature inside the projector.
Air Circulation
Exhaust Vent
(Hot air exhaust)
Air Intake Vent Air flow
The projector uses a lamp which generates 
significant heat. The cooling fans and air vents are 
provided to dissipate the heat by drawing air into the 
housing and the filter is located in the intake vents to 
prevent dust from getting inside of the projector.
In order to care for the projector appropriately, 
regular cleaning is required. Remove any dirt or dust 
that has accumulated on the projector.
If the projector reaches a time set in the timer 
setting, a Filter replacement icon (Fig. 1) appears on 
the screen and WARNING FILTER indicator on the 
top panel lights up (see below), indicating that the 
filter replacement is necessary.
If the projector detects that the filter is clogged and 
no scroll is left in the filter cartridge, a Filter cartridge 
replacement icon (Fig. 2) appears on the screen and 
WARNING FILTER indicator on the top panel lights 
up (see below). Stop using the projector immediately 
and replace the filter cartridge.
Blocking the air vents and leaving the projector 
uncleaned for a long time may not only damage the
