Starting up the projector
1. Plug the power cord into the projector and into a 
power outlet. Turn on the power outlet switch 
(where fitted). Check that the POWER indicator 
light on the projector lights orange after power has 
been applied.
Please use the original accessories (e.g. power cord) only 
with the device to avoid possible dangers such as electric 
shock and fire.
2. Press  POWER on the projector or   ON on the remote control to start the 
projector. As soon as the lamp lights up, a Power On Tone will be heard. The 
POWER indicator light flashes green and stays green when the projector is on.
The start up procedure takes about 30 seconds. In the later stage of start up, a startup 
logo is projected.
(If necessary) Rotate the focus ring to adjust the image clearness.
To turn off the ring tone, see Turning off the Power On/Off Ring Tone on page 37 for 
details.
If the projector is still hot from previous activity, it will run the cooling fan for approximately 90 
seconds before energizing the lamp.
3. If the projector is activated for the first time, 
select your OSD language following the on-
screen instructions.
4. If you are prompted for a password, press the 
arrow keys to enter a six-digit password. See 
Utilizing the password function on page 25 for 
details.
5. Switch all of the connected equipment on.
6. The projector will start to search for input 
signals. The current input signal being scanned 
displays in the upper left corner of the screen. If 
the projector doesnt detect a valid signal, the message “No Signal” will continue 
displaying until an input signal is found.
Yo u  c a n  a l s o  p r e s s  SOURCE on the projector or remote control to select your desired 
input signal. See Switching input signal on page 28 for details.
If the frequency/resolution of the input signal exceeds the projectors operating range, you will 
see the message “Out of Range” displayed on a blank screen. Please change to an input 
signal which is compatible with the projectors resolution or set the input signal to a lower 
setting. See Timing chart on page 76 for details.

Adjusting the projected image
Adjusting the projection angle
The projector is equipped 4 adjuster feet. These adjusters change the image height and 
projection angle. To adjust the projector:
Screw the rear adjuster feet to fine-tune the 
horizontal angle.
To retract the feet, screw the adjuster feet in a 
reverse direction.
If the projector is not placed on a flat surface or 
the screen and the projector are not 
perpendicular to each other, the projected image 
becomes trapezoidal. To correct this situation, 
see Correcting keystone on page 23 for details.
Auto-adjusting the image
In some cases, you may need to optimize the picture quality. To do this, press AUTO on the 
projector or remote control. 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 PC signal (analog RGB) is selected.
Fine-tuning the image size and clarity
Do not look into the lens while 
the lamp is on. The strong light 
from the lamp may cause 
damage to your eyes.
Be careful when you press the 
quick-release button as it is 
close to the exhaust vent where 
hot air comes from.
1. Adjust the projected image to the size 
that you need using the zoom ring.2. Sharpen the image by rotating the 
focus ring.

							Operation 28
Switching input signal
The projector can be connected to multiple devices at the same time. However, it can only 
display one full screen at a time. When starting up, the projector automatically searches for 
the available signals.
Be sure the Quick Auto Search function in the SOURCE menu is On if you want the 
projector to automatically search for the signals.
To select the source:
1. Press SOURCE on the projector or remote 
control. A source selection bar is displayed. 
2. Press / until your desired signal is selected 
and press MODE/ENTER.
If available, you can also select the source by

control.
Once detected, the selected source information 
will be displayed at the corner of the screen for 
seconds. If there is multiple equipment connected 
to the projector, repeat steps 1-2 to search for 
another signal.
•  The brightness level of the projected image will 
change accordingly when you switch between 
different input signals. Data (graphic) PC 
presentations using mostly static images are 
generally brighter than Video using mostly moving 
images (movies).
•  The native display resolution of this projector is in a 
4:3 aspect ratio. For best display picture results, you should select and use an input signal 
which outputs at this resolution. Any other resolutions will be scaled by the projector 
depending upon the “aspect ratio” setting, which may cause some image distortion or 
loss of picture clarity. See Selecting the aspect ratio on page 29 for details.
•  Firewall in the PC must be switched off to allow QPresenter and USB Display to work.
Changing Color Space

Selecting the aspect ratio
The “aspect ratio” is the ratio of the image width to the image height. Most analog TV and 
some computers are in 4:3 ratio, and digital TV and DVDs are usually in 16:9 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 signal.
To change the projected picture ratio (no matter what aspect the source is):
• Using the remote control
1. Press ASPECT to show the current setting.
2. Press ASPECT repeatedly to select an aspect ratio to suit the format of the video signal 
and your display requirements.
• Using the OSD menu
1.
Press MENU/EXIT 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. 
						

							Operation 30
About the aspect ratio
•  In the pictures below, the black portions are inactive areas and the white portions are 
active areas.
•  OSD menus can be displayed on those unused black areas.
1.Auto: Scales an image proportionally to fit 
the projectors native resolution in its 
horizontal or vertical width. This is suitable 
for the incoming image which is neither in 
4:3 nor 16:9 and you want to make most use 
of the screen without altering the images 
aspect ratio.4.16:9: Scales an image so that it is 
displayed in the center of the 
screen with a 16:9 aspect ratio. 
This 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.Real
: The image is projected as its original 
resolution, and resized to fit within the 
display area. For input signals with lower 
resolutions, the projected image will display 
smaller than if resized to full screen. You 
could adjust the zoom setting or move the 
projector towards the screen to increase the 
image size if necessary. You may also need 
to refocus the projector after making these 
adjustments.5.16:10: Scales an image so that it is 
displayed in the center of the 
screen with a 16:10 aspect ratio. 
This is most suitable for images 
which are already in a 16:10 
aspect, as it displays them without 
aspect alteration.
3.4:3: Scales an image so that it is displayed in 
the center of the screen with a 4:3 aspect 
ratio. This is most suitable for 4:3 images 
like some computer monitors, standard 
definition TV and 4:3 aspect DVD movies, 
as it displays them without aspect 
alteration.
