   NOTE: The lens shift dial for LEFT-RIGHT cannot be rotated one-half turn or more.
Do not over rotate it or it may break. 
NOTE: Shifting the lens to the maximum in two directions combined will cause the edges of the image to become dark or will 
cause some shadows. 
TIP: The  lens  shift  dial  for  UP-DOWN  can  be  rotated  one  turn  or  more,  but  not  beyond  the  adjustable  range  defined  below.  
NOTE: Lens shift is not available with the NP01FL optional lens. The NP01FL should be used only for “zero degree” applica-
tions.

Adjusting the Tilt Foot
1. Lift the front edge of the projector.
CAUTION:
Do  not  try  to  touch  the  ventilation  outlet  during Tilt  Foot  adjustment 
as it can become heated while the projector is turned on and during 
its cool down period after it is turned off.
2.  Push up the Adjustable Tilt Foot Levers on the right and left sides 
of the projector to extend the adjustable tilt feet (maximum height).
3. Lower the front of the projector to the desired height. 
4.  Release the Adjustable Tilt Foot lever to lock the Adjustable tilt foot.
  There  is  approximately  10  degrees  (up)  of  adjustment  for  the  front  of 
the projector.

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.
TIP: For  operating  the  [KEYSTONE]  screen,  see  “  Correcting  Keystone  Dis-
tortion” on page 30.

 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 keystone-type distortion, resulting in a crisp, square image.
The following procedure explains how to use the [KEYSTONE] screen from the menu to correct trapezoidal distortions.
When the projector is placed diagonally to the screen, 
When the projector is set up at an angle in relation to the screen, adjust the Horizontal option of the Keystone menu 
so that the top and bottom of sides of the projected image are parallel.
1. Press  the  3D  REFORM  button  on  the  remote  control  or  the  projec-
tor cabinet.
  The Keystone screen will be displayed on the screen.
2. Press the SELECT  button to select [VERTICAL] and then use the 
SELECT  or  so that the left and right sides of the projected im-
age are parallel.
* Adjust the vertical keystone distortion.
3.  Align the left (or right) side of the screen with the left (or right)\
 side 
of the projected image.
•  Use the shorter side of the projected image as the base.
• In the right example, use the left side as the base.
4. Press the SELECT  button to select [HORIZONTAL] and then use 
the  SELECT   or   so  that  the  top  and  bottom  sides  of  the  pro-
jected image are parallel.
•  Adjust the horizontal keystone distortion.

NOTE:
• If the projection angle is the same as in the last use, the previous cor\
rection setting values are retained in the memory.
• When doing Step 2, adjust the position of image so that the screen is sm\
aller than the area of the projected area.
• To reset the 3D Reform correction setting values, press and hold the 3D R\
EFORM button for a minimum of 2 seconds.
•  Each time the 3D REFORM button is pressed, the item will change as follows: KEYSTONE → CORNERSTONE → None → KEY-
STONE → ...
For information on [CORNERSTONE], see “Correcting Horizontal and Vertical Keystone Distortion (Cornerstone)” on page 40.
• The  Cornerstone  adjustment  will  not  be  available  during  the  Keystone  adjustment.  To  perform  the  Cornerstone  adjustment, 
press and hold the 3D REFORM button for a minimum of 2 seconds to reset the Keystone correction setting values. The Key-
stone adjustment will not be available during the Cornerstone adjustment. To perform the Keystone adjustment, press and hold 
the 3D REFORM button for a minimum of 2 seconds to reset the Cornerstone\
 correction setting values.
• The 3D Reform feature can cause an image to be slightly blurred because the correction is made electronically.
3. Projecting an Image (Basic Operation)
5. Repeat steps 2 and 4 to correct keystone distortion.
6.  After completing Keystone correction, press the EXIT button.
  The Keystone screen will disappear.
• To perform Keystone correction again, press the 3D REFORM button 
to display the Keystone screen and repeat above steps 1 to 6.

MAGNIFY (+) button or when the menu is displayed.
NOTE:
• Some signals may take time to display or may not be displayed correctly.

Setting the function switch
There are two switches on the bottom of the battery case: an applicable projector selector switch (1) and laser en-
able/disable  switch  (2).  Check  the  projector  being  used  and  decide  whether  to  enable  or  disable  laser,  then  set 
these  switches  as  necessary  using  the  tip  of  a  thin  ball-point  pen.  On  this  model,  an  applicable  projector  selector 
switch (1) is not used.

 Turning off the Projector
To turn off the projector:
3. Projecting an Image (Basic Operation)
1. Press  the  POWER  (ON/STAND  BY)  button  on  the  projector 
cabinet  or  the  POWER  OFF  button  on  the  remote  control. 
The [POWER OFF / ARE YOU SURE?] message will appear.
 
2.  Press the ENTER button
After the projector turns off, the cooling fans keep operating for 
a while (Cooling-off time).
The  cooling  fans  stop  operating  when  the  projector  turns  off 
and goes into standby mode.
When  in  standby  mode,  the  POWER  indicator  will  light  orange 
and the STATUS indicator will light green.
3.  After making sure that the projector is in standby mode, turn 
off the Main Power switch. The power indicator will go out.
About Direct Power Off
The  projector  has  a  feature  called “Direct  Power  Off ”. This  fea-
ture allows the projector to be turned off (even when projecting 
an  image)  using  the  Main  Power  Switch  or  disconnecting  the 
AC power supply.
NOTE: Before using Direct Power Off, be sure to allow at least 20 min-
utes  immediately  after  turning  on  the  projector  and  starting  to  display 
an image.
CAUTION
•  Do not unplug the power cable from the wall outlet or projec-
tor  when  the  projector  is  powered  on.  Doing  so  can  cause 
damage  to  the  AC  IN  connector  of  the  projector  and  (or)  the 
prong plug of the power cable. To turn off the AC power sup-
ply  when  the  projector  is  powered  on,  use  the  Main  Power 
Switch.
• Do  not  turn  off  the  AC  power  supply  within  10  seconds  of 
making adjustment or setting changes and closing the menu.
 Doing so can cause loss of adjustments and settings and re-
turn to default.
 After Use
Preparation: Make sure that the main power is turned off.
1. Unplug the power cable.
2.  Disconnect any other cables.
3.  Retract adjustable tilt feet if extended.
4.  Cover the lens with the lens cap.
