CHECK THE AIR FLOW
The internal portion temperature is rising. 
Please turn the power OFF, and allow the unit to cool down 
at least 20 minutes. After having confirmed the following 
items, please turn the power ON again. 
 • Is there blockage of the air passage aperture? 
 • Is the air filter dirty? 
 • Does the peripheral temperature exceed 35°C?
If the same indication is displayed after the treatment, 
please set the HIGH at the FAN SPEED of the item 
SERVICE of the OPTION menu.
CLEAN THE AIR FILTERPOWER OFF FIRST,
THEN CLEAN THE AIR  FILTER.
AFTER CLEANING THE AIR  FILTER,
RESET THE FILTER TIMER.A note of precaution when cleaning the air filter. 
Please immediately turn the power OFF, and clean or 
change the air filter by referring to the “Air Filter” section of

NOTE  • A lamp has a finite product life. Lamps are characterized by the 
fact that, after long hours of usage, a lamp will no longer light up, or the lamp 
will break or burst, etc. This projector is equipped with an automatic shut-down 
function, such that the power will automatically be turned off when lamp usage 
time has reached 2000 hours. Please be aware, however, that among lamp 
types, there are major differences in product lifetimes; a lamp may thus fail to 
light even prior to the functioning of the automatic shut-down function of this 
projector.

NOTE    • Be sure to check jack type, signal level, timing and resolution 
before connecting this projector to a computer.
• Some computers may have multiple display screen modes. Use of some of \
these modes will not be possible with this projector.
• Depending on the input signal, full-size display may not be possible i\
n some 
cases. Refer to the number of display pixels above.
• Although the projector can display signals with resolution up to UXGA 
(1600x1200), the signal will be converted to the projector’s panel resolution 
before being displayed. The best display performance will be achieved if the 
resolutions of the input signal and projector panel are identical.
• Automatically adjustment may not function correctly with some input sign\
als.
• The image may not be displayed correctly when the input sync signal is a\
  composite sync or a sync on G.
