Precautions
Precautions
Follow all warnings, precautions and maintenance as
recommended in this user’s guide to avoid injury, fire, electric
shock, and to maximize the life of your projector.
Warning—Do not look into the projector’s lens when the lamp is
on. The bright light may hurt your eyes. Never let children look
directly into the lens when the light is on.
Warning—Do not look into the laser beam or shine it into others’
eyes when using the remote control as a laser pointer. Laser light
seriously damage eyes.
can
Warning—Make sure that the projector is grounded properly by
connecting the power cord to a grounded electric AC outlet. Always
use the power cord that comes with your projector. Do not use an
ungrounded adapter with the grounded plug.
Warning—Except for the lamp cover, never open or disassemble
the product as this may cause electric shock. Dangerous electrical
voltages inside the projector can cause severe injury.
Warning—Do not overload wall outlets, extension cords, or multiplug receptacles as this can result in a risk of fire or electric shock.
Place the unit near an easily accessible wall socket. Do not place
the cord where it may be stepped on or become a tripping hazard.
Warning—To reduce the risk of fire or electric shock, do not
expose this product to rain or moisture. Do not place drinks on top
of the projector. Spilled drinks can cause an electric shock hazard
and can also damage the projector. If liquid or any solid object falls
into the cabinet, have the projector checked by a qualified
technician before operating it further.
Warning—Do not place your hands or objects near the ventilation
slots. The air coming out of the slots is hot. Do not block the
ventilation slots or place anything near these slots that may block
the free flow of air. Blocked ventilation may cause internal heat
build-up and cause picture degradation or damage to the projector.
Warning—The ventilation fan continues to operate after the
projector is powered off and until the projector is sufficiently cooled
down. Do not unplug the power cord until the fan stops.
Warning—Keep the plastic packaging material away from children,
especially small children. The plastic bags may result in death by
suffocation.

Do’s and Don’ts
Precautions
Do:
• Operate the projector in a well-ventilated room to avoid a
buildup of ozone from the projector’s high-performance lamp.
• Turn off the projector before cleaning.
• Use a dampened soft cloth to clean the display housing.
• Disconnect the power plug from AC outlet if the projector is not
being used for a long period of time.To disconnect the cord, pull
it out by the plug. Do not pull on the cord.
• Use lint-free gloves or finger cots when changing the lamp.
Never touch a lamp with your bare hands. The invisible residue
from the natural oil on your hands may shorten the lamp life.
Don’t:
• Place the projector on an unstable cart, stand, or table. If the
projector falls, it may be seriously damaged.
• Operate the projector near paper, cloth, or other combustible
material, or in proximity to inflammable substances, such as
paint thinner. Never operate the projector if covered with
combustible materials. The projector gets hot and combustible
and inflammable materials may catch fire.
• Use abrasive cleaners, waxes or solvents to clean the
projector.
• Use under the following conditions:
— In extremely hot, cold or humid environment.
— In areas susceptible to excessive dust and dirt.
— Near any appliance generating a strong magnetic field.
— In direct sunlight.
— Near any heat source, such as radiators, heat registers,
stoves, or other products (including amplifiers) that produce
heat.
— In a smoky area. Smoke residue may cause buildup on
critical parts, including the lens.
Attempt to service the projector yourself. Opening or removing
the coverings of the internal components may damage them
and void your warranty.

Changing the Lamp
Precautions When Changing a Lamp
The projector automatically monitors the lamp life. As the lamp
reaches the end of its life, the image becomes darker and the color
hues weaker. The projector’s Lamp LED turns red to let you know
that the lamp must be changed soon before it fails completely.
When you see the red Lamp LED, please change the lamp as soon
as possible.
Note that lamp lifetimes vary according to the operating
environment and type of use. Lamp lifetimes are not guaranteed
and some lamps may end their lifetimes earlier than others.
NOTE: To order a new replaceable lamp module, please go to
www.xeroxprojectors.com.
• The lamp module is the only user-replaceable part in the
projector. To prevent electric shock, do not open the projector
case.
• Always wear protective gloves and eyeglasses when fixing or
replacing the lamp. Lamp contains mercury.
• To reduce the risk of personal injury, do not drop the lamp
module or touch the lamp bulb at any time. The lamp module
may explode if handled incorrectly, and may shatter and cause
injury if dropped.
• The lamp is hot! If you touch the lamp, you may scald your
fingers. Allow the projector to cool down at least 45 minutes
before opening the lamp compartment or changing the lamp.
• In the event that the lamp is dropped or broken, and explodes
or bursts, please leave the area immediately and ventilate it for
at least 30 minutes.
• Do not operate the projector with the lamp cover removed.
• Do not attempt to reuse an old lamp. An old lamp may explode
if reused.
