✔Note:
•   
The  overlapping  area  might  become  uneven  depending  on  the  images.  In  such  a  case,  it  is  recommended  to 
decrease the contrast of the images in the Image Adjust Menu.
If the colors of the left and right images do not match, then follow the next step.
Select Color matching in the setting menu and display the Color matching dialog box.
Then, set Color matching to On and adjust the color settings (Red/Green/Blue).

Color matching
✔Note:
•   
When you change the values of Target, make sure that each 
Target  value  should  be  within  the  range  of  Measured  value. 
(e.g.,  In  the  case  of  the  Fig.1,  the  X  value  of Target-Red 
should  be  within  0.674  which  is  the  X  value  of  Measured-
Red.)
Set to On.
5Set Test pattern to On to display a 50 % white image. The overlap area will be brighter than the non-overlapping area. 
Adjust the Black level in the Edge blending dialog box to increase the brightness of the non-overlapping area so that 
the unevenness is reduced.
Select Advanced color matching if you need further adjustment.
In the Advanced color matching dialog box, set Advanced color matching to On and adjust the values of Target (Red/Green/ 
Blue/ Cyan/ Magenta/ Yellow/ White). 
7
If color unevenness is still detected between the left image 
and right image, measure chromaticity coordinates and 
luminance of Red, Green, and Blue by using a colorimeter, 
and then input the measured values by following the steps 
below.
1.    Ensure that the Advanced color matching function is set 
to “On”.
2.    Highlight “Test pattern” appearing at the lower part of the 
window and press the SELECT button to display the Test 
pattern window.
3.    Select Red, Green, or Blue and press the SELECT button 
to display the test pattern. 
4.    Measure chromaticity coordinates (X and Y) and 
luminance (Lx) by using a colorimeter. 
5.    Highlight “Exit” in the Test pattern window and press the 
SELECT button to return to the Advanced color matching 
window. 
6.    Highlight the color of the coordinates and luminance that 
you measured at the step 4, in the Measured section, and 
press the SELECT button.
7.    Input the measured chromaticity coordinates and 
luminance values in the x and y fields. 
8.    The values to be input in the L fields can be calculated 
according to the following formula:
   L = Measured luminance of the color ÷ total measured  
    luminance of all colors (Red, Green, and Blue)
. 
9.    Readjust the Target values.
10.  Highlight “Store” appearing at the lower part of the 
Advanced color matching window and press the SELECT 
button to store the values.

WARNING: 
						

							
77

This projector uses high-pressure lamps which must be handled carefully and properly. 
Improper handling may result in accidents, injury, or create a fire hazard.
l Lamp  lifetime  may  differ  from  lamp  to  lamp  and  according  to  the  environment  of  use. There  is  no 
guarantee  of  the  same  lifetime  for  each  lamp.  Some  lamps  may  fail  or  terminate  their  lifetime  in  a 
shorter period of time than other similar lamps.
l If  the  projector  indicates  that  the  lamp  should  be  replaced,  i.e.,  if  the  LAMP  REPLACE  indicator 
lights  up,  replace  the  lamp  with  a  new  one  after  the  lamps  have  cooled  down.  (Follow  carefully  the 
instructions  in  the  Lamp  Replacement  section  of  this  manual.)  Continuous  use  of  the  lamp  with  the 
LAMP REPLACE indicator lighted may increase the risk of lamp explosion.
l Lamp  may  explode  as  a  result  of  vibration,  shock  or  degradation  as  a  result  of  hours  of  use  as  its 
lifetime  draws  to  an  end.  Risk  of  explosion  may  differ  according  to  the  environment  or  conditions  in 
which the projector and lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFET y PRECAUTIONS SHOULD BE TAKEN.
If  a  lamp  explodes,  disconnect  the  projector’s  AC  plug  from  the  AC  outlet  immediately.  Contact  an 
authorized  service  center  for  a  checkup  of  the  unit  and  replacement  of  the  lamp.  Additionally,  check 
carefully to ensure that there are no broken shards or pieces of glass around the projector or coming out 
from  the  cooling  air  circulation  holes.  Any  broken  shards  found  should  be  cleaned  up  carefully.  No  one 
should  check  the  inside  of  the  projector  except  those  who  are  authorized  trained  technicians  and  who 
are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those 
who are not appropriately trained to do so, may result in an accident or injury caused by pieces of broken 
glass.

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 or cover to protect it from dust and 
scratches.
Cleaning the Projection Lens
CAUTION
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.
