WARNINGHIGH 
VOLTAGEHIGH
TEMPERATUREHIGH
PRESSURE
The projector uses a high-pressure mercury glass lamp. The lamp can break with a loud 
bang, or burn out, if jolted or scratched, handled while hot, or worn over time. Note that 
each lamp has a different lifetime, and some may burst or burn out soon after you start 
using them. In addition, when the bulb bursts, it is possible for shards of glass
to fly into 
the lamp housing, and for gas containing mercury
to escape from the projector’s vent 
holes
About disposal of a lamp
• This product contains a mercury lamp; do not put in trash. Dispose of in accord with 
environmental laws.
• For lamp recycling, go to www.lamprecycle.org. (in USA)
• For product disposal, contact your local government agency or www.eiae.org (in the 
US) or www.epsc.ca (in Canada).
• For more information, call your dealer.
Disconnect 
the plug from 
the power 
outlet
• If the lamp should break (it will make a loud bang when it does), unplug the 
power cord from the outlet, and make sure to request a replacement lamp 
from your local dealer. Note that shards of glass could damage the 
projector’s internals, or cause injury during handling, so please do not try to 
clean the projector or replace the lamp yourself.
• If the lamp should break (it will make a loud bang when it does), ventilate the 
room well, and make sure not to breathe the gas that comes out of the 
projector vents, or get it in your eyes or mouth.
• Before replacing the lamp, make sure the power switch is off and the power 
cable is not plugged in, then wait at least 45 minutes for the lamp to cool 
sufficiently. Handling the lamp while hot can cause burns, as well as 
damaging the lamp.
• Do not open the lamp cover while the projector is suspended from above. 
This is dangerous, since if the lamp’s bulb has broken, the shards will fall out 
when the cover is opened. In addition, working in high places is dangerous, 
so ask your local dealer to have the lamp replaced even if the bulb is not 
broken.
• Do not use the projector with the lamp cover removed. At the lamp replacing, 
make sure that the screws are screwed in firmly. Loose screws could result 
in damage or injury.
• Use only the lamp of the specified type 
.
• If the lamp breaks soon after the first time it is used, it is possible that there 
are electrical problems else where besides the lamp. If this happens, contact 
your local dealer or a service representative.
• Handle with care: jolting or scratching could cause the lamp bulb to burst 
during use.
• If the indicators or a message prompts you to replace the lamp (see the 
section “Related Messages” and “Regarding the indicator Lamps”), replace 
the lamp as soon as possible. Using the lamp for long periods of time, or 
past the replacement date, could cause it to burst. Do not use old (used) 
lamps; this is a cause of breakage.RLU-150-001 
						

							Lamp Life
Projector lamps have a finite life. The projected images will become darker and hues will become weaker 
after a lamp has been used for a long period of time.
The LAMP indicator also becomes red when the lamp unit reaches a high temperature. Before replacing the 
lamp, switch the POWER OFF, wait approximately 20 minutes, then switch the POWER ON again. If the 
LAMP indicator still displays red, replace the lamp.
Replacing the Lamp
All projector lamps will wear out eventually. If used for long periods of time, the image could become 
darkened, and the color contrast could be impacted as well. We recommend that you replace your lamps early. 
If the LAMP indicator turns red, or a message prompts you to replace the lamp when you power up the 
projector, the lamp needs to be replaced.
1
Turn off the projector, and unplug the power cord. Allow the lamp bulb to cool for at least 45 minutes, and 
prepare a new lamp
2
After making sure that the projector has cooled adequately, slowly flip over the projector, so that the 
bottom is facing up
3
Unscrew the 2 screws, and remove the lamp cover
4
Unscrew the 1 screw, and slowly pull out the lamp by the handle
• Be careful not to touch the inside of the lamp case.
5
Insert the new lamp, and tighten the 1 screw firmly to lock it in place
• Also steadily push the opposite side of the screwed side of the lamp into the unit.
6
Replace the lamp cover, and tighten the 2 screws firmly to lock it in place
7
Slowly turn the projector so that the top is facing up
8
Turn on the projector power, and using the menu, reset the lamp timer
• To reset the lamp timer, from the OPTION menu, select LAMP TIME.

							ATTENTION:
• Make sure that the screws are screwed in firmly. Loose screws could result in damage or injury.
• Do not use with lamp cover removed.
• Do not reset the lamp timer without replacing the lamp. 
NOTE:
The LAMP indicator is also red when the lamp unit reaches high temperature.
Before replacing the lamp, switch power OFF, wait approximately 20 minutes, and switch power ON again. If 
the LAMP indicator is still red, replace the lamp.
Caring for the Air Filter
The air filter should be cleaned about every 100 hours. Clean the filter if the LAMP indicator and TEMP 
indicator blink red simultaneously, or if a message prompts you to clean the air filter when you turn on the 
unit, the filter needs to be cleaned. (Refer to “On-Screen Messages” in the Trouble-shooting section.)
1
Turn off the projector, then unplug the power cord
2
To clean a reusable filter, carefully vacuum both sides of the filter area.
3
If the filter is damaged and needs to be replaced, contact your dealer or ViewSonic Corp. Replace the old 
filter then put the grill back in place.
4
To reset the Filter Timer, turn on the projector power, go to the Option menu then select filter timer. Reset 
the filter timer.
CAUTION:
• Switch power OFF and remove the power cord from the power outlet before beginning maintenance work.
• Replace the air filter if contamination cannot be removed or if it is damaged.
• Do not use the equipment with the air filter removed.
• When the air filter becomes clogged with dust etc., the power supply may switch OFF automatically to 
prevent the temperature from rising inside the projector.
• Make sure the lens is cool before cleaning.
• Do not use detergents or solvents such as benzene or thinners.
• Do not use chemical sprays.
• Use a soft cloth or lens paper only.

							Caring for the Inside of the Projector
In order to ensure the safe use of your projector, please have it cleaned and inspected by an authorized Service 
Provider approximately once every 2 years. Never try to care for the inside of the unit yourself. Doing so is 
dangerous.
Caring for the Lens
Lightly wipe the lens with a commercially available lens-cleaning wipe. Do not touch the lens directly with 
your hand.
Caring for the Cabinet and Remote Control Transmitter
Wipe lightly with gauze or a soft cloth. If soiling is severe, dip a soft cloth in water or a neutral cleanser 
diluted in water, and wipe lightly after wringing well. Then, wipe lightly with a soft, dry cloth.
CAUTION:
• Make sure to turn off the power and unplug the power cord before caring for the unit. Please care-fully 
• Do not use cleaners or chemicals other than those listed above, including benzene and paint thinner.
• Do not use aerosols or sprays.
• Do not polish or wipe with coarse material.
• Gently wipe with a soft cloth. If dirt and stains etc. are not easily removed, use a soft cloth dampened with 
water, or water and a neutral detergent, and wipe dry with a soft, dry cloth.
