LAMP REPLACEMENT
When the projection lamp reaches its end of life, the Lamp
Replacement icon appears on the screen and the LAMP 1/2
REPLACE indicator lights orange. Replace the lamp with a
new one promptly. The timing when the LAMP 1/2
REPLACE indicators should light depends on the lamp mode.
NOTES: 1) The Lamp replacement icon will not appear when
the Display function is set to “Off”, or during “Freeze”. 2) It
is recommended that both lamps be changed at the same time
in order to maintain picture quality (better color balance and
brightness). Figure 1 Lamp Replacement Icon

Always power down and disconnect/disengage all power sources to the
projector before servicing or cleaning.
Allow the projector to cool for at least 45 minutes before the lamp cover is
opened. The inside of the projector can become very hot and may cause injury.
Do Not operate the projector while any of the lamps are removed. This may
result in malfunctions, fire hazard, or other possible accidents.
NOTICES: 1) For continued safety, replace with a lamp assembly of the same type. 2) Do not drop
the lamp assembly or touch a glass bulb! The glass can shatter and may cause injury.
Use the Lamp Status Display to verify which lamp needs to be
replaced.
1. Loosen the lamp cover screw (Figure 1-Top) and lift the
cover.
2. Loosen the 2 screws (Figure 1-Bottom) that attach the
lamp unit to the projector.

REPLACING THE FILTER CARTRIDGE
Always power down and disconnect/disengage all power sources to the
projector before servicing or cleaning.
Allow the projector to cool for at least 45 minutes before the lamp cover is
opened. The inside of the projector can become very hot and may cause injury.
NOTE: To maintain normal internal ventilation replace the filter unit periodically.
1. Use a vacuum cleaner to remove dust on and around the filter
cover (Figure 3-Top-Left).
2. Lift and pull the bottom clips to remove the filter cover
(Figure 3-Top-Right).
3. Pinch and pull the filter clips to remove the filter unit (Figure
3-Bottom-Left).
4. Use a vacuum cleaner to remove dust on and around the
intake vents of the projector (Figure 3-Bottom-Right).
5. Install the new filter unit into the place.
6. Install the filter cover.
NOTICES: 1) Make sure the filter cartridge is correctly inserted
into the projector otherwise, the projector cannot be turned on. 2)
Do not block the air vents. Doing so may result in malfunction of
the projector. 3) When using the projector under dusty or smoky
conditions, dust may accumulate on a lens, liquid crystal panels,
or optical elements inside the projector. Such conditions may
degrade the quality of the projected image. When the symptoms
above are noticed, contact your authorized dealer or service
station for proper cleaning.
