For continued safety, replace with a lamp  
of the same type. Do not drop the lamp 
or touch the glass bulb! The glass can 
shatter and may cause injury.
Allow a projector to cool for at least 45 minutes before 
you open the lamp cover. The inside of the projector can 
become very hot.
CAUTION
CAUTION
When the projection lamp of the projector reaches its end of life, the Lamp replacement icon appears on

Maintenance and Care
Lamp Replacement
When replacing the lamp because it has stopped 
illuminating, there is a possibility that the lamp may be 
broken.
If replacing the lamp of a projector which has been 
installed on the ceiling, you should always assume that 
the lamp is broken, and you should stand to the side of 
the lamp cover, not underneath it. Remove the lamp cover 
gently. Small pieces of glass may fall out when the lamp 
cover is opened.
If pieces of glass get into your eyes or mouth, seek 
medical advice immediately.

Unplug the AC power cord before cleaning.
Gently wipe the projection lens with a cleaning cloth that 
contains a small amount of non-abrasive camera lens 
cleaner, or use a lens cleaning paper or commercially 
available air blower to clean the lens. 
Avoid using an excessive amount of cleaner. Abrasive 
cleaners, solvents, or other harsh chemicals might scratch 
the surface of the lens.
Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning 
cloth. When the cabinet is heavily soiled, use a small 
amount of mild detergent and finish with a soft dry 
cleaning cloth. Avoid using an excessive amount of 
cleaner. Abrasive cleaners, solvents, or other harsh 
chemicals might scratch the surface of the cabinet.
When the projector is not in use, put the projector in 
an appropriate carrying case to protect from dust and 
scratches.
Maintenance and Care
Cleaning the Projection Lens
Cleaning the Projector Cabinet
Do not use any flammable solvents or air sprays on the projector and in its vicinity. The explosion or fire 
hazard may occur even after the AC power cord is unplugged because the temperature inside the projector 
is extremely high due to the lamps. In addition, there is a risk that the internal parts may be damaged not 
only by the flammable air spray but also by the cold air.

The WARNING indicators show the state of the function which protects the projector. Check the state of the 
WARNING indicators and the POWER indicator to take proper maintenance. 
The projector is shut down and the WARNING TEMP.
indicator is blinking red.
When the temperature inside the projector reaches a
certain level, the projector will be automatically shut down 
to protect the inside of the projector. The POWER indicator 
is blinking while the projector is being cooled down. When 
the projector has cooled down enough (to its normal 
operating temperature), it can be turned on again by 
pressing the ON/STAND-BY button.

Then check the matters below:
–   Did you provide appropriate space for the projector to be 
ventilated? Check the installing condition to see if the air 
vents of the projector are not blocked.
–   Has the projector been installed near an Air-Conditioning/ 
Heating Duct or Vent? Move the installation of the 
projector away from the duct or vent.
–  Is the filter clean? Replace the filter with a new one.
The projector is shut down and the LAMP indicator is 
lighting and other indicators are blinking.
When the projector detects an abnormal condition, it 
will be automatically shut down to protect the inside 
of the projector and the LAMP indicator lights on and 
other indicators blink. In this case, unplug the AC 
power cord and plug it, and then turn on the projector 
once again to verify operation. If the projector cannot 
be turned on and these indicators are still lighting and 
blinking, unplug the AC power cord and contact the 
service center.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE 
AC POWER CORD CONNECTED UNDER AN 
ABNORMAL CONDITION. IT MAY RESULT IN 
FIRE OR ELECTRIC SHOCK.
