The projector automatically makes optimum positional settings for the input signal.
•If the image is not projected in the correct position even after you press the AUTO POSITION button (or
AUTO button) several times, change the settings in the SIGNAL SETTING menu to put the image in the
correct position. (See Page 29.)
•When you carry out this procedure with a dark image, the image may be displaced.

Replacing the lamp
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 separately sold that is exclusive to HC2000. Contact your dealer for
purchase of the lamp.
WARNING:
•Be sure to turn off the main power switch and unplug the power cord from the wall outlet before replacing the
lamp. Lamp replacement without turning off the main power switch may result in electric shock.
•Be careful not to drop the lamp fixing screws into the inside of the projector. Don’t put a metal piece or
flammable object into the projector. Using the projector with any foreign object present inside may result in
electric shock or fire. 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 fire.
•Don’t shake the removed lamp or don’t lift it above your face. You may be injured in your eye by flying or
falling glass fragments.
•Don’t replace the lamp immediately after use because the lamp cover is 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 turn off the main power switch, unplug the power cord,
and wait at least one hour to allow the lamp to cool down enough to the touch.
CAUTION:
When the lamp operating time exceeds 1470 hours*1, a warning indication is displayed on the screen for one
minute. When it exceeds 1500 hours*1, *2, the warning indication is kept displayed on the screen. In such a case,
replace the lamp with a new one immediately.
•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 has 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.
•Don’t replace the lamp with the projector installed on the ceiling. Glass fragments may fall from the projector,
entering your eye or mouth causing injury.
•Dispose of the used lamp according to the local regulations and rules.
*1) Time when the projector is used with LAMP MODE set to NORMAL. When it is set to LOW, this period of
time becomes longer.
*2) About 3000 hours at the maximum
To replace the lamp:
1. Loosen the lamp cover fixing screw (a) using a hexagon
wrench (2-face, 3 mm).
2. Slide the lamp cover to the side and remove it from the
projector.
3. Loosen three lamp box fixing screws (b) using a flatblade
driver.
4. Lift the handle.
Handle
