  Using the projector
EnglishSecuring the projector
Using a security cable lock
The projector has to be installed in a safe place to prevent stealing. If not, purchase a lock, like Kensington lock, to 
secure the projector. You can locate a Kensington lock slot on the rear side of the projector. See item 12 on page 8 
for details. 
A Kensington security cable lock is usually the combination of key(s) and lock. Refer to the lock’s documentation 
about 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.

respectively represent 4 digits (1, 2, 3, 4). According to the password you 
desire to set, press the arrow keys on the remote control or projector to 
enter six digits for the password.
Once the password is set, the OSD menu returns to the Password page.
IMPORTANT: The digits being input will display as asterisks on-
screen. Write your selected password down here in this manual in 
advance or right after the password is entered so that it is available 
to you should you ever forget it.
Password: __ __ __ __ __ __
Keep this manual in a safe place.
5. To leave the OSD menu, press MENU.
If you forget the password
If the password function is activated, you will be asked to enter the six-digit 
password every time you turn on the projector. If you enter the wrong 
password, the password error message as pictured to the right displays lasting 
for three seconds, and the Input Password page follows. You can retry by 
entering another six-digit password, or if you did not record the password in 
this manual, and you absolutely do not remember it, you can use the 
password recall procedure. See Entering the password recall procedure on 
page 22 for details.
If you enter an incorrect password 5 times in succession, the projector will

  Using the projector
EnglishAdjusting the projected image
Adjusting the projection angle 
There are four 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 23 for details.
Correcting 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 pictures 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 base of the 
lens level with the top or bottom edge of the screen.
2. If the picture is stilled distorted, or the projector is unable to be positioned as described above, you will 
need to manually correct the picture.
• Using the remote control or projector
i. Press one of the Arrow keys on the remote control ( ,  ) or 
projector ( / ,  / ) to display the Ke ystone page.
ii. See step iv below for further operation.
• Using the OSD menu
i. Press MENU and then press  /  until the Display menu is 
highlighted.
ii. Press  to highlight Ke ystone and press ENTER. The Ke ystone page 
displays.
iii. Highlight 2D Keystone and press ENTER. The keystone correction 
page displays.
iv. Press the key whose keystone icon is similar 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 pictures shape will stop changing. You will not be 
able to change the picture further in that direction.

There are many different shades 
that are considered to be white 
for various purposes. One of the 
common methods of representing 
white color is known as the “color 
temperature”. A white color with a 
low color temperature appears to 
be reddish white. A white color 
with a high color temperature 
appears to have more blue in it.

Color Management
In most installation situations, color management will not be necessary, such as in classroom, meeting room, or 
lounge room situations where lights remain on, or where building external windows allow daylight into the 
room. 
Only in permanent installations with controlled lighting levels such as boardrooms, lecture theaters, or home 
theaters, should color management be considered. Color management provides fine color control adjustment to 
allow for more accurate color reproduction, should you require it.
Proper color management can only be achieved under controlled and reproducible viewing conditions. You will 
need to use a colorimeter (color light meter), and provide a set of suitable source images to measure color 
reproduction. These tools are not provided with the projector, however, your projector supplier should be able to 
provide you with suitable guidance, or even an experienced professional installer.
The Color Management provides six sets (RGBCMY) of colors to be adjusted to favorite colors. When you select 
each color, you can independently adjust its color range and saturation according to your preference.
To adjust and store the settings:
1. In the Picture -- Advanced menu, highlight Color Management and 
press ENTER. The Color Management page displays.
2. Highlight Primary Color and press  /  to select a color from among 
Red, Ye l l o w, Green, Cyan, Blue, and Magenta.
3. Press   to highlight Range and press  /  to select the color range you 
wish to make adjustment. The bigger the range, the more proportions of 
its two adjacent colors the color contains. 
Please refer to the illustration to the right for how the colors relate to 
each other. For example, if you select Red and set its range at 0, only pure 
red is selected. Increasing its range will include both the red color close to 
yellow and red color close to magenta.
4. Press   to highlight Saturation and adjusts the color saturation level by 
pressing / . 
If you select Red and set its range at 0, only the saturation of the pure red 
will be affected. 
Saturation is the amount of that color in a video picture. Lower 
settings produce less saturated colors; a setting of “0” removes that 
color from the image entirely. If the saturation is too high, that color 
will be overpowering and unrealistic.
5. To leave and save the settings, press MENU once or EXIT twice.

							30 Using the projector  
EnglishSelecting the aspect ratio
The aspect ratio is the ratio of the image width to the image height. Digital TV is usually in 16:9 ratio, which is 
the default for this projector, and most analog TV signals and DVDs are in 4:3 ratio.
With the advent of digital signal processing, digital display devices like this projector can dynamically stretch and 
scale the image output to a different aspect than that of the image input source. Images can be stretched in a 
linear manner so the whole of the image is stretched equally, or non-linearly, which distorts the image. 
To change the projected picture ratio (no matter what aspect the source is):
• Using the remote control
Press one of the aspect ratio buttons to suit the format of the video signal and 
your display requirements.
•Using the OSD menu
1. Press MENU and then press  /  until the Display menu is highlighted.
2. Press   to highlight Aspect Ratio.
3. Press  /  to select an aspect ratio to suit the format of the video signal 
and your display requirements.
About the aspect ratio
1.Anamorphic (ANA): Scales an image so that it is displayed in the center 
of the screen with a 16:9 aspect ratio. This setting stretches and resizes 
linearly, except that it treats the vertical and horizontal dimensions 
independently. It stretches the height of the source image until it reaches 
the full projected height, and stretches the width of the source image 
until it reaches the full projected width. This may alter the projected 
aspect, depending upon the original aspect of the source image. 
Anamorphic is most suitable for images which are already in a 16:9 
aspect, like high definition TV, as it displays them without aspect 
alteration.
2.4:3: Scales a picture so that it is displayed in the center of the screen with 
a 4:3 aspect ratio. This is most suitable for 4:3 pictures like computer 
monitors, standard definition TV and 4:3 aspect DVD movies, as it 
displays them without aspect alteration.
3.Letter Box (LB): Scales a picture to fit the projector’s native resolution in 
its horizontal width and resize the picture’s height to the 3/4 of the 
projection width. This may produce a picture greater in height than can 
be displayed, so part of the picture is lost (not displayed) along the top 
and bottom edges of the projection. This is suitable for the display of 
movies which are presented in letter box format (with black bars on the 
top and bottom).
4.Wide: Stretches the picture horizontally in a non-linear manner, that is, 
the edges of the picture are stretched more than the center of the picture 
to prevent distortion of the central part of the picture. This is suitable for 
occasions where you want to stretch the width of a 4:3 aspect picture to 
the width of a 16:9 aspect screen. It does not alter the height. Some 
widescreen movies have been produced with their width squashed down 
to the width of a 4:3 aspect, and are best viewed when restretched back to 
their original width using this setting.
