PREPARATION
Installation
Installation Precautions
yyUse the projector in a well-ventilated
environment.
- To prevent excessive internal heat,
install the projector in a well-ventilated location. Do not place anything
near the projector, as this may block
its air vents. If the air vents are
blocked, the internal temperature
increases.
- Do not place the projector on a
carpet or rug. If the projector's inlet
vent is on the bottom, be careful not
to block the vent and always use the
projector on a solid, level surface.
- Be sure to prevent foreign objects,
such as paper and debris, from
entering the projector.
- Leave adequate distance (at least
30 cm) around the projector.
17
yyDo not place the projector in a hot or
humid environment.
- Do not place the projector in a hot,
cold, or humid environment.
yyDo not place the projector in a place
where it can attract dust.
- Otherwise, this may result in fire.
yyDo not remove any covers, except for
the lens cap. There is a high risk of
electric shock.
yyThe projector is manufactured
using high-precision technology.
You may, however, see tiny black
dots and/or bright colored dots that
continuously appear on the projector
screen. This is a normal result of the
manufacturing process and does not
indicate a malfunction.
yyThe remote control may not work
in an environment where a lamp
equipped with electronic ballasts or
a three-wavelength fluorescent lamp
is installed. In this case, replace the
lamp with a standard international
lamp for the remote control to work
properly.

PREPARATION
Projection Distance per Screen Size
1 Place the projector on a sturdy, level surface, together with the computer or audio/
video source.
2 Place the projector at an appropriate distance from the screen. The distance between the projector and the screen determines the actual size of the image.
3 Position the projector so that the lens is perpendicular to the screen. If the lens is not
perpendicular to the screen, the projected image will look distorted. To correct the
distortion, use the Keystone function. (See 25 page)

Replacing the Lamp
Replacing the Lamp
The lifespan of the lamp depends on
the environment in which the projector
is used.
You can check how long the projector
lamp has been used in the OPTION
menu. Make sure to replace the lamp in
the following situations:
yyThe projected image gets darker or
the quality deteriorates.
yyThe lamp warning indicator is red.
yyThe “Replace the lamp” message
appears on the screen when turning
the projector on.
Be careful when replacing
the lamp
yyTurn off the power by pressing the
POWER button on the remote control or control panel.
yyDo not remove the power cord when
the operation indicator is flashing
orange, i.e. the fan is working (about
20 seconds). When the operation
indicator is orange and no longer
flashing, remove the power cord.
yyAllow the lamp to cool for one hour
before replacing it.
yyReplace only with the same type of
lamp from an LG Electronics Service Center. Using another manufacturer's lamp may damage the
projector and lamp.
yyOnly pull the lamp out when replacing it.
yyKeep the lamp unit out of reach of
children. Keep the lamp away from
heat sources, such as radiators
and stoves. There is a fire or burn
hazard.
yyDo not expose the lamp to liquids
or foreign materials. The lamp may
burst.
yyDo not insert flammable or metal
objects into the lamp socket after
removing the lamp. This can result
in electrical shock or damage the
product.
yySecurely tighten the new lamp with
screws. If it is not securely tightened, the projected image may
become darker and there may be a
fire hazard.
yyDo not touch the front glass of the
new lamp or the glass of the lamp
container. Picture quality and lamp
lifespan may suffer.
Purchasing a
replacement lamp
Check the lamp model and then purchase the replacement lamp from an LG
Electronics Service Center.
(Use a lamp designed specifically for the
projector; otherwise, it may damage the
projector.)
Disposing of lamps
Dispose of a used lamp by returning it to
an LG Electronics Service Center.

yyIt is possible for data in a USB device
to become damaged, so it is recommended to back up important files.
Users are responsible for data management. The manufacturer bears no
responsibility.
yyIt is recommended to use a USB
flash drive that is 32 GB or less and
a USB hard disk that is 1 TB or less.
Any USB device with more than the
recommended capacity may not work
properly.
yyIf a USB storage device is not working properly, disconnect it and reconnect it.
yyIf a USB external hard drive with the
power saving function does not work,
turn the hard drive off and on again to
make it work properly.
yyUSB storage devices below USB 2.0
are supported as well. However, they
may not work properly in the movie

Cleaning the Lens
If there is any dust or staining on the
lens surface, you must clean the lens.
Use an air spray or a cleaning cloth to
clean the lens.
To remove dust or stains, use an air
spray or apply a small amount of cleaning agent to a swab or soft cloth and
gently rub the lens.
Make sure that liquid does not flow into
the lens if the product is sprayed directly
onto the lens.
Cleaning the Projector
Case
To clean the projector case, first unplug
the power cord.
To remove dust or stains, use only a
soft, dry, lint-free cloth.
Do not use alcohol, benzene,
thinners, or other chemicals, as they

Cleaning the Vents
Dust and foreign material tend to adhere
to the vents.
It is important to use a vacuum cleaner
to periodically remove dust and foreign
material.
Using the projector with excessive dust
