About color temperature
There are different kinds of white color. Color temperature is a way to show the differences in white. White of which 
temperature is low appears reddish. When the color temperature rises, white appears bluish. For example, you can 
change the color temperature using the following procedures.
To rise the color temperature: Increase the CONTRAST B (blue) and decrease the CONTRAST R (red).
To reduce the color temperature: Decrease the CONTRAST B (blue) and increase the CONTRAST R (red).
If you set all of CONTRAST R, G, and B to negative values, the original brightness of the image can’t be 
obtained even when you maximize CONTRAST in the IMAGE menu.

This projector is equipped with a lamp to project images. This lamp is a consumable. It may burn out or its brightness 
may decrease during use. In such cases, replace the lamp with a new one as soon as possible. Be sure to replace the 
lamp with a new lamp sold separately that is exclusive to this projector. Contact your dealer for purchase of the lamp.
Spare lamp VLT-HC7000LP
Warning:
Be careful not to drop the lamp fi xing screws inside of the projector. Don’t put a metal piece or fl ammable object 
into the projector. Using the projector with any foreign object present inside may result in electric shock or fi re. 
When you can’t remove the foreign object from the inside, contact your dealer for removal.
Be sure to install the lamp securely. When the lamp isn’t installed properly, it won’t illuminate. Improper installation 
may also result in fi re.
Don’t shake the removed lamp or don’t lift it above your face. Your eyes may be injured by fl ying or falling glass 
fragments.
Don’t replace the lamp immediately after use because the lamp cover will be very hot. You may get burned. Turn 
off the power using the POWER button. After the lamp goes out, wait about two minutes until the intake and 
exhaust fans for cooling the lamp stop rotating. Then unplug the power cord, and wait at least one hour to allow 
the lamp to cool down enough to the touch.
Do not touch the lamp directly. It may break and cause injury or burn.
Interval of lamp replacement
The recommended interval of lamp replacement is about 5000 hours*1*2 of consecutive use. Such interval differs 
depending on the operating environment and may be shorter than 5000 hours*1*2. Decrease in luminescence and/or 
color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 3750 hours*1, 
the indicator will blink alternately between green and red (while the lamp is lit; when the lamp is not lit, the indicator 
will be lit red only) and the lamp replacement message will appear on the screen for one minute everytime the lamp 
is turned on. When the lamp has been used for about 4750 hours*
1, the replacement message (LAMP EXCHANGE) 
will appear on the screen for one minute every 25 hours*1 thereafter. When the lamp operation time exceeds 5000 
hours*1*2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp 
operation time is reset.
*1:  Duration when LAMP MODE of the INSTALLATION menu is set to LOW. When it is set to STANDARD, this duration will be 
shorted.
*2:  When LAMP MODE is set to STANDARD, this duration will be shorted to 2000 hours.
Caution:
Don’t remove the lamp for any purpose other than replacement. Unnecessary removal of the lamp may result in a 
breakdown.
This projector uses a high-pressure mercury lamp as the light source. The high-pressure mercury lamp may 
explode or fail to illuminate permanently because of an impact, scratch, or deterioration through use. The period 
of time until explosion or permanent failure to illuminate varies considerably from lamp to lamp, depending on 
operation conditions. Therefore, the lamp may explode soon after the start of use.
The possibility of explosion of the lamp increases if you use it beyond its replacement period. When the instruction 
of lamp replacement appears, replace it with a new one immediately even if the lamp is still lighting normally.
When the high-pressure mercury lamp explodes, glass fragments will scatter inside or outside the lamp box and 
the gas charged inside the lamp will diffuse inside or outside the projector. The gas inside the lamp contains 
mercury. Be careful not to breathe it or avoid it from entering your eye or mouth. If you should breathe it or if it 
should enter your eye or mouth, see a doctor immediately.
In the event that the high-pressure mercury lamp exploded, glass fragments may have been scattered inside the 
projector. Ask your dealer to replace the lamp and to inspect the inside of the projector. When you clean or replace 
the lamp by yourself, be sure to hold the handle of the lamp. You may get injured by glass fragments.
When removing the lamp from the ceiling-mounted projector, use the lamp replacement tray packed with the 
projector or option lamp to prevent glass fragments from scattering.
Be sure to use the lamp exclusive to this projector, VLT-HC7000LP. Use of other lamps may cause a failure of the 
projector. •

and the lamp operation time is reset successfully.
The projector doesn’t turn on if the lamp cover isn’t 
attached securely.
Be sure to reset the lamp operation time whenever 
you replace the lamp.
Do not reset the lamp operation time unless you 
replace the lamp.
The lamp is fragile. If it is broken, be careful not to 
cut yourself with glass fragments.
Caution:
This projector uses a lamp that 
contains mercury. Disposal of the lamp 
or the projector with the lamp may 
be regulated due to environmental 
considerations. For disposal or 
recycling information, please contact 
your local authorities or the Electronic 
Industries Alliance: www.eiae.org. (For

Warning:
Never use fl ammable air duster or other materials when cleaning the air-fi lter. Flammable substances may ignite 
causing fi re or breakdown when the lamp is illuminated.
Do not use fl ammable solvents (benzene, thinner, etc.) and fl ammable aerosols when cleaning the projector body 
and lens. Flammable substances may ignite causing fi re or breakdown while the lamp is illuminating.
Caution:
Be sure to turn off the lamp and unplug the power cord from the wall outlet before you perform any maintenance on 
the projector.
Cleaning of the air-fi lter
Clean the air-fi lter frequently (about once a month). If the air-fi lter or ventilation grilles become clogged with dirt or 
dust, the temperature inside the projector may rise and cause troubles, such as damage to the inside parts and 
shortening the life of the panels.
When the temperature inside the projector rises, the STATUS 
indicator will blink orange and the lamp will be turned off.
Loosen two screws that are fi xing the right side panel using a 
Phillips screwdriver (+) and remove the panel from the projector. 
Remove the fi lter from the right side panel.
(1)  Remove the holder by pushing the tab of the holder on the air-
fi lter in the direction of the arrow.
(2)  Remove the air-fi lter (white), spacer, and air-fi lter (gray).
Clean dirt and dust adhering to the air-fi lter using a vacuum.
For the air-fi lter (white) 
If stubborn stains persist, wash the air-fi lter with water 
and dry well in the shade.
For the air-fi lter (gray) 
If stubborn stains persist, wash the air-fi lter with diluted 
detergent, rinse with water, and dry well.
Attach the fi lter to the right side panel.
(1)  Attach the air-fi lter (gray), spacer, and air-fi lter (white) to the 
side panel, aligning their notches with that of the side panel. 
(2)  Insert the right tab of the holder to the side panel and push the 
left tab in the direction of the arrow to attach the side panel.
Attach the right side panel to the projector and fi x it with two 
screws. 
Important:
If the air-fi lter is damaged or becomes extremely dirty, change it 
with a new air-fi lter. Contact your dealer for a new air-fi lter.
Use the dedicated air-fi lter only.
Caution:
Be sure to use the projector with an air-fi lter. If not, dust may get inside the projector causing fi re and failure.
Cleaning of the projector and the ventilation slots
Use a soft cloth to clean the projector and the ventilation grilles. When the grilles become dirty, wipe them with a soft 
cloth dampened with diluted mild detergent, and then wipe them with a dry cloth.
To protect the surface of the projector from fading or deteriorating:
Do not spray insecticide on or inside the projector.
Do not use benzine or thinner to clean it.
Do not let rubber or plastic materials contact with projector.
Cleaning of the lens
Use a standard lens-cleaning brush or a piece of lens tissue dampened with lens cleaning fl uid. The lens surface is 
fragile. Use only recommended, nonabrasive lens-cleaning materials. Do not touch the lens with your fi ngers. •
