The projector has to be installed in a safe place to prevent theft. Otherwise, purchase a lock, such as the 
Kensington lock, to secure the projector. You can locate a Kensington lock slot on the projector. See item 
25 on page 9 for details. 
A Kensington security cable lock is usually a combination of key(s) and the lock. Refer to the locks 
documentation for finding out how to use it.
Utilizing the password function
For security purposes and to help prevent unauthorized use, the projector includes an option for setting 
up password security. The password can be set through the On-Screen Display (OSD) menu. Once the 
password is set and this function is selected, the projector is password-protected. Users who do not 
know the correct password can not use the projector.
You will be inconvenienced if you activate the password functionality and subsequently forget the password. 
Print out this manual (if necessary) and write the password you used in this manual, and keep the manual in 
a safe place for later recall.

EnglishAdjusting the projected image
Adjusting the projection angle 
There are two adjuster feet on the bottom of the projector. 
These can be used if necessary to change the projection angle. 
Screw the feet in or out as appropriate to aim and level the 
projection angle.
If the screen and the projector are not perpendicular to each 
other, the projected image becomes vertical trapezoidal. To 
correct this problem, see Correcting picture distortion on 
page 28 for details.
Auto-adjusting the image
In some cases, you may need to optimize the picture quality. To do this, 
press AUTO. Within 3 seconds, the built-in Intelligent Auto Adjustment 
function will re-adjust the values of Frequency and Clock to provide the 
best picture quality.
The current source information will be displayed in the corner of the 
screen for 3 seconds.
This function is only available when a PC signal (analog RGB) is selected.
Fine-tuning the image size and clarity
1. Adjust the projected picture to the size 
that you need using the zoom ring.2. Sharpen the picture by rotating the focus 
ring. 
						

							28 Using the projector  
EnglishCorrecting picture distortion
Keystoning occurs when the projector is not perpendicular to the screen and is where the projected 
picture displays visible as a trapezoid shape like either of the following:
•  Two parallel sides (left and right, or top and bottom) but is noticeably wider on either side.
•  No parallel sides.
To correct the picture’s shape, you can perform the following steps.
1. Adjust the projection angle. Move the projector to be in front of the center of the screen with the 
center of the lens level with the screen.
2. If the picture is still distorted, or the projector is unable to be positioned as described above, you will 
need to manually correct the picture by using the 2D Keystone and Corner Fit functions. 
The 2D Keystone function is closely related to the Corner Fit function as both make adjustments to correct 
picture distortion. When correcting picture distortion, use the following procedure to adjust 2D Keystone 
and Corner Fit functions in order to achieve the best picture shape:
1. Use 2D Keystone function to adjust the picture roughly to the correct shape.
2. Use Corner Fit funtion to fine tune the corners to acheive best picture shape.
3. If optimal effect cannot be achieved using Corner Fit, reset 2D Keystone and repeat steps 1 and 2.
2D Keystone and Corner Fit functions are closely correlated, when 2D Keystone is over adjusted, the 
adjustment range for Corner Fit will be limited. 
Using 2D Keystone function
•  Using the remote control or projector keypad
i. Press one of the Arrow/Keystone keys (Left  / , Up  / , 
Right  / , Down / ) to display the 2D Keystone page.
ii. See step iii below for further operation.
•  Using the OSD menu
i. Press MENU/EXIT and then press  /  until the Display 
menu is highlighted.
ii. Press  to highlight 2D Keystone and press MODE/
ENTER. The 2D Keystone page is displayed.
iii. Press the key whose keystone icon is opposite to the shape of the projected picture. Continue 
pressing the same key or press the other keys until you are satisfied with the shape.
The values on the lower portion of the page change while pressing. When the values reach their 
maximum or minimum with repeated key presses, the picture’s shape will stop changing. You will 
not be able to change the picture further in that direction.
iv. If desired picture shape cannot be achieved, press MODE/ENTER to reset 2D Keystone 
value and repeat the previous step.
When resetting 2D Keystone, both 2D Keystone and Corner Fit values will return to default value.
v.When done, press MENU/EXIT to go back to the previous page.

EnglishUsing the preset and user modes
Selecting a preset mode
The projector is preset with several pre-defined picture modes so that you can choose one to suit your 
operating environment and input source picture type.
To select a picture mode that suits your need:
• Press MODE/ENTER repeatedly until your desired mode is 
selected.
•  Using the OSD menu
1. Press MENU/EXIT and then press  /  until the Picture menu is 
highlighted.
2. Press   to highlight Picture Mode.
3. Press  /  until your desired mode is selected.
These modes consist of preset values suitable for various projection situations as described 
below:
• Bright: Maximizes the brightness of the projected image. This mode is suitable for environments 
where extra-high brightness is required, such as using the projector in well lit rooms.
• Presentation: Is designed for presentations. The brightness is emphasized in this mode to match PC 
and notebook coloring.
• sRGB: Maximizes the purity of RGB colors to provide true-to-life images regardless of brightness 
setting. It is most suitable for viewing photos taken with an sRGB compatible and properly calibrated 
camera, and for viewing PC graphic and drawing applications such as AutoCAD.
• Cinema: Is appropriate for playing colorful movies, video clips from digital cameras or DVs through 
the PC input for best viewing in a blackened (little light) environment.
• 3D: 
This projector supports playing three-dimensional (3D) content transferred through your 3D-
compatible video devices and contents, such as game consoles (with 3D game discs), 3D Blu-ray players 
(with 3D Blu-ray discs), 3D TV (with 3D channel), and so on. 
When watching 3D contents:
• The image may seem misplaced, however, this is not a product malfunction.
• Take appropriate breaks when watching 3D content.
• Stop watching 3D content if you feel fatigue or discomfort.
• Keep a distance from the screen of about three times the effective height of the screen when watching 
3D content.
• Children and people with a history of oversensitivity to light, heart problems, or have any other 
existing medical condition should be refrained from watching 3D content.  
• User 1/User 2: Recalls the customized settings. See Setting the User 1/User 2 mode on page 32 
for details.
