INSTRUCTIONS
LAMP REPLACEMENT
The projector uses a high-pressure mercury glass lamp which can explode with a loud
bang, or burn out, if jolted or scratched or handled while hot, or wear out over time. If the lamp should
explode, immediately disconnect all power sources to the projector. Ventilate the room well, and make sure
not to breathe the gas that comes out of the projector vents. Avoid contact with eyes and mouth.
Do not use an old (used) lamp as this may cause it to explode.
Do Not operate a projector while any lamp is removed. This may result in malfunctions, fire
hazard, or other accidents.
When replacing a lamp that has burnt out, 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. Shards of glass
may damage internal projector components or cause injury during handling.
Never unscrew except the appointed (marked by an arrow) screws.

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.
NOTICES: 1) Use only the lamp of the specified type. 2) A lamp that explodes soon after first use, may be
experiencing electrical problems other than the lamp itself. If this occurs, contact your local dealer or a
service representative. 3) Overuse of a lamp can cause the picture to darken, not to light up or to explode.
When the pictures appears dark, or when the color tone is poor, replace the lamp as soon as possible.

FILTER REPLACEMENT
Always disconnect all power sources to the projector before servicing
When replacing a filter, 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. Shards of glass may damage
internal projector components or cause injury during handling.
NOTICES: 1) Use only the specified air filter. 2) Do not use the projector with the air filter and/or the filter
cover removed. It could result in a fire and/or malfunction to the projector. 3) The air filter should be cleaned
periodically. If the air filter becomes clogged by dust or similar, internal temperatures may rise and could
cause a heat build-up and/or malfunction to the projector.
NOTES: 1) Replace the air filter when it is damaged or too soiled, and also when you replace the lamp. 2)
Reset the filter time only when you have cleaned or replaced the air filter, for a suitable indication about the air
filter. 3) The projector may display the message “CHECK THE AIR FLOW” or turn itself off, to prevent the
internal heat level from rising too high.
The filter prevents dust from accumulating on the optical elements inside the projector. Should the filter
become clogged with dust particles, the effectiveness of the cooling fans will be reduced and may result in
internal heat buildup which will adversely affect the life of the projector.
NOTE: When the projector is suspended from the ceiling, use a vacuum cleaner to remove dust that has
accumulated on and around the filter cover to avoid dust from entering the compartment when the filter cover
is removed.
