Note on Startup screen (Menu Language Select screen)
When  you  first  turn  on  the  projector,  you  will  get  the  Startup  menu.  This  menu  gives  you  the  opportunity  to  select 
one of the 21 menu languages.
To select a menu language, follow these steps:
1.   Use the SELECT  button to select one of the 21 lan-
guages for the menu.
2.  Press the ENTER button to execute the selection.
After  this  has  been  done,  you  can  proceed  to  the  menu 
operation.
If  you  want,  you  can  select  the  menu  language  later.  (→ 
[L ANGUAGE] on page 91)
NOTE:
•
  The projector cannot be turned off for 60 seconds after the lamp is turn\
ed on and while the POWER indicator is blinking green.
•
  If you turn on the projector immediately after the lamp is turned off or when the ambient temperature is high, the cooling fans 
will run for a moment and then you will get an image on the screen.
•
 
Immediately after turning on the projector, screen flicker may occur. This is normal. Wait 3 to 5 minutes until the lamp lighting 
is stabilized.
•
  When the Lamp mode is set to Eco, the Lamp indicator will light green.
•
  If one of the following things happens, the projector will not turn on.
-
  If the internal temperature of the projector is too high, the projector detects abnormal high temperature. In this 
condition  the  projector  will  not  turn  on  to  protect  the  internal  system.  If  this  happens,  wait  for  the  projector’s 
internal components to cool down.
-
 
When the lamp reaches its end of usable life, the projector will not tur\
n on. If this happens, replace the lamp.
 
(
→ page 117)
-
 
If the lamp fails to light, and if the STATUS indicator flashes on and off in a cycle of six times, wait a full minute 
and then turn on the power.
NOTE: Turning the Main Power Switch Off then Back On 
Allow a minimum of 5 seconds between turning off the main power switch a\
nd turning it back on again.
The same will be applied when a power strip equipped with a switch and a\
 breaker is used.
Failing to do so could result in no power to the projector. (There will be no stand-by LED) 
Should this happen, unplug the power cable and plug it in again. Turn on the main power switch.

NOTE:  Your  “Keystone”  correction  data  can  be  reset  by  pressing  and  holding 
the 3D REFORM button for a minimum of 2 seconds.
CAUTION:
Do  not  use  the  tilt-foot  for  purposes  other  than  originally  intended. 
Misuses such as using the tilt foot to carry or hang (from the wall or 
ceiling) the projector can cause damage to the projector.
The rear foot height can be adjusted up to 0.5 inch/13 mm.
Rotate  the  rear  foot  to  the  desired  height  in  order  to  square  the  image 
on the projection surface, but the vertical distance from the bottom to the 
desk  or  floor  should  be  0.5  inch  /13mm  to  make  the  projector  horizontal 
on the flat surface.
TIP: For  operating  the  [KEYSTONE]  screen,  see  “  Correcting  Keystone  Dis-
tortion” on page 26.

 Correcting Keystone Distortion
When the projector is not exactly perpendicular to the screen, keystone distortion occurs. To overcome it, you can use the 
“Keystone” function, a digital technology that can adjust for keys\
tone-type distortion, resulting in a crisp, square image.
The following procedure explains how to use the [K EYSTONE] screen from the menu to correct trapezoidal distortions.
When the projector is set up at an angle in relation to the screen, adju\
st the Horizontal option of the Keystone menu 
so that the top and bottom of sides of the projected image are parallel.\
Auto Keystone Correction
The Auto Keystone correction feature will correct vertical distortion of\
 a projected image on the screen. No special
operation required. Just put the projector on a flat surface.
To use the Auto Keystone function, first you must select [AUTO KEYSTON\
E] in [KEYSTONE] from the menu.
