Using the remote control as a computer mouse - Wireless mouse function 
The supplied remote mouse receiver enables you to operate your computers mouse functions 
from the remote control.  It is a great way to control your computer-generated presentations. 
• The cursor key on the remote control operates the computer mouse functions. 
• If a Windows computer is connected, the L-CLICK button on the remote control operates as 
the computer mouse left click button and the R-CLICK button as the computer mouse right 
click button. 
• If the Macintosh computer is connected, the L-CLICK and R-CLICK buttons operate in the 
same way as the computer mouse click button. 
• While the menu is displayed on the screen (see page 18), the cursor key, L-CLICK and R-
CLICK buttons will operate to control the menu. 
 
Before connecting: 
• Turn off the computer, and then remove the current mouse. 
•  Connect the computer and remote mouse receiver with the supplied serial mouse cable as 
shown in the above illustration. 
• The projector and computer will be turned on as described in Using the Projector on page 
13.  Do not turn on either the computer or unit until you read this section.  
• Please also refer to the manual of the computer to be connected.

							Operation  
Using the Projector 
1) Connect the supplied power cable to the projector, then to the wall outlet (the mains). The 
POWER indicator on top of the unit lights in amber. 
 
2) Press the POWER ON button on the remote control or the POWER button on t\
op of 
the unit to turn on the unit. 
The POWER indicator on top of the unit turns to green and start blinking. It will take about 
one minute for the projector to be ready to use.  Wait until the indicator stops blinking and 
lights steadily in green. 
Note: While the POWER indicator is blinking, the unit doesnt turn off even if you press the 
POWER OFF button on the remote control or the POWER button on the unit. 
 
3) Turn on the connected source (computer, VCR, DVD player, etc.). 
       If you use a video component, start playback for screen/image adjustment. 
 
4) Press VIDEO or RGB to select the input source. 
 You can also select the input source with the menu operation. 
Notes 
• If the blue, black or focus pattern screen (the background type differs depending on the 
BACKGROUND setting.) is projected, check the following: 
- Is the source is properly connected to the unit? 
- Is the source component or computer turned on? 
- Is the video signals are coming to the projector? 
• The video resolution of the connected computer can be changed.  
      
      5)  Adjust the position and height of the unit. 
Move the unit to the position where the projected image is horizontally centered to the screen. 
The internal keystone adjustment can adjust for some horizontal problems, but the best image 
is obtained when the projector is optimality positioned. 
• When the projected image is offset horizontally 
Adjust the position of the unit so that the unit is square to the screen 
• When the projected image is offset vertically 
Adjust the height balance of the unit with the adjusters. 
Using the adjusters to adjust the height balance 
There are two adjusters one on the front and one on the side. 
To lower the position of the screen, pull out the folded leg of the rear adjuster. 
For the side adjuster, rotate the adjuster until the unit is horizontally parallel to the screen. 
 
6)  Adjust the focus with the focus ring and if required use the keystone adjustment to 
parallel the side of the image with the screen. 
 
7) Change the unit setting to suit to the projecting method and selected source as described 
in step 4. 
• Select the type of projection 
 If the projected image is horizontally reversed or upside down, change the projection type.  
See page 16. 
• If the component video signal output jacks of the video component are connected to the 
RGB IN connector, set the RGB input to YCbCr in the menu. 
This setting can provide a better picture image. 
 13 
						

							• Adjust the projected image from the source connected to the RGB IN connector. 
The resolutions most suitable to the incoming signals will automatically be selected.  
However, if any vertical banding, noise, dot interference, or crosstalk appears on the screen, 
adjust PICTURE ADJ, then FINE PICTURE using the menus.  You can also adjust the 
horizontal and vertical position of the image. 
 
8)  Adjust the picture elements and select the picture type. 
     Adjust the picture elements; select the picture type according to the video contents and 16:9. 
 
9)  Start using the Projector. 
The following functions are available while using the Projector: 
• Adjusting the speaker volume, 
• Freezing a moving picture, and 
• Enlarging the picture. 
 
Image Turns Off 
If POWER OFF is set to ON, the image will be turned off if the unit has been projecting a 
blank screen for five minutes with an RGB input source. 
If the image is suddenly turned off while projecting a computer image, the computers screen 
saver or the units POWER OFF function may be activated. 
 
Turning the Projector Off 
1) 
Operating with the remote control:  Press the POWER OFF button a little bit longer. 
Operating with the projector keypad  1. Press the POWER button. 
        POWER OFF/ENTER appears on the screen. 
     2. Press ENTER 
When the projector is turned off, the POWER indicator will start blinking then turn to amber in 
about one minute. 
***Never turn off the POWER switch (main power) while the POWER indicator is blinking.*** 
 
2) If the POWER indicator is lit in amber, press the O side of the PO\
WER switch  
     (main power) on the projector back. 
The POWER indicator goes out.  
Disconnect the power cord if it is not to be used for an extended period\
. 
 
Changing computers video resolutions 
Depending on your computers graphic capability, you may be able to select one of several 
resolutions.  Generally a computer- either a PC or Macintosh- with 1 MB VRAM will run: 
640 x 480 at 16.7 million colors (24 bit True color) 
800 x 600 at 65,000 colors. 
1024 x 768 at 256 colors. 
As the resolution increases, the number of colors you can run decreases.  With 2 MB VRAM a 
computer will run: 
640 x 480 at 16.7 million colors (24 bit True color). 
800 x 600 at 16.7 million colors (24 bit True color). 
1024 x 768 at 65,000 colors. 
1280 x 1024 at 256 colors.

Notebook computers and resolution standards 
This Projector is designed to project industry-standardized video such as VESA (Video 
Electronics Standards Association) or VGA (Video Graphics Array).  Notebook computers do not 
use industry standards.  They use whatever timing is necessary to match their local LCD display.  
The end result is typically not standard.  By turning off your notebooks display, the timing 
parameters are a bit more like the real VESA or VGA signal. 
 
Adjusting the volume of the projector speaker 
Press VOLUME + to increase the volume or - to decrease. 
The volume can also be adjusted with the menu operation. 
 
Turning off the image and muting the sound temporarily 
Press the MUTE button. The image will turn off and the sound will be muted at the same time.  
To restore the picture and sound, press the MUTE button again. 
 
Freezing a moving picture 
You can capture the desired frame of the moving picture. 
Press the FREEZE button. A still image of the current frame will be displayed.  To restore the 
present picture, press the button again. 
Tip: The still picture can also be enlarged.

according to the incoming signals from the RGB IN connector (When RGB is set to 
STANDARD.  However, you may need manual adjustment depending on the computer or 
video component connected to the RGB IN connector.  If you have any of vertical banding, noise, 
dot interference, or crosstalk on the projected picture, adjust clock frequency with PICTURE 
ADJ then clock phase with FINE PICTURE (see next page).  You can also adjust the
