							Connection 22
Connection
When connecting a signal source to the projector, be sure to:
1. Turn all equipment off before making any connections.
2. Use the correct signal cables for each source.
3. Ensure the cables are firmly inserted. 
In the connections shown below, some cables may not be included with the projector (see 
Shipping contents on page 8). They are commercially available from electronics stores.  
Many notebooks do not turn on their external video ports when connected to a projector. 
Usually a key combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a 
function key labeled CRT/LCD or a function key with a monitor symbol on the notebook. Press 
FN and the labeled function key simultaneously. Refer to your notebooks documentation to find 
your notebooks key combination.

Connecting video source devices
You need only connect the projector to a video source device using just one of the 
connecting methods, however each provides a different level of video quality. The method 
you choose will most likely depend upon the availability of matching terminals on both the 
projector and the video source device as described below: 
Connecting audio
The projector has two built-in speaker which are designed to provide basic audio 
functionality accompanying data presentations for business purposes only. They are not 
designed for, nor intended for stereo audio reproduction use as might be expected in 
home theater or home cinema applications.
The built-in speaker will be muted when the AUDIO OUT jack is connected.
If the selected video image is not displayed after the projector is turned on and the correct video 
source has been selected, check that the video source device is turned on and operating 
correctly. Also check that the signal cables have been connected correctly.

							Connection 24
Playing sound through the projector
You can make use of the projector speaker in your presentations, and also connect 
separate amplified speakers to the AUDIO OUT socket of the projector.
If you have a separate sound system, you will most likely want to connect the audio output 
of your Video source device to that sound system, instead of to the audio projector.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD) 
menus.
The table below describes the connection methods for different devices, and where the 
sound is from.

The selected input signal determines which sound will be played by the projector speaker, and 
which sound will be output from the projector when AUDIO OUT is connected. If you select the 
COMPUTER/PC signal, the projector can play the sound received from AUDIO IN mini jack. If you 
select the COMPONENT/VIDEO signal, the projector can play the sound received from AUDIO 
(L/R).

Operation
Starting up the projector
1. Plug the power cord into the projector and into a 
wall socket. Turn on the wall socket 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 cable) only 
with the device to avoid possible dangers such as electric 
shock and fire.
2. Press POWER on the projector   or remote control   to start the projector 
and a start up tone sounds. 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 45 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. To use the OSD menus, please set them to 
your familiar language first. 
4. If you are prompted for a password, press the 
arrow keys to enter a five digit password. See 
Utilizing the password function on page 31 
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.
You can also press SOURCE on the projector or remote control to select your 
desired input signal. See Switching input signal on page 33 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 71 for details.
To maintain the lamp life, once you turn the projector on, wait at least 5 minutes before turning 
if off.
Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 3 adjuster feet. These adjusters change the image height 
and projection angle. To adjust the projector:
Please select language
Press Enter to confirm, Exit to leave 
						

							Operation 26
Screw adjuster foot to fine tune the horizontal 
angle.
To retract the foot, hold up the projector then 
slowly lower the projector. Screw the adjuster foot 
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 2D Keystone on page 27 for details.
• 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 adjuster button as it is close to the exhaust vent where hot air 
comes from. 
						

							Operation27
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 upper left corner of the screen for 
3 seconds. 
• The screen will be blank while AUTO is functioning.
• This function is only available when PC signal (analog RGB) is selected.
Fine-tuning the image size and clarity
Sharpen the image by rotating the FOCUS ring.
Correcting 2D Keystone
2D Keystone function enables a wider projector installation area compared to 
conventional projectors with limited positioning in front of the screen.
To correct this, you will need to manually correct it following one of these steps.
• Using the projector or remote control 
Press  /  on the projector or remote 
control to display the 2D Keystone  page. Press ▲/▼ to adjust 
vertical values from -30 to 30. Press ◄/► to adjust horizontal 
values from -30 to 30.

to 100.
Corner Fit and 2D Keystone Adjustment Notice
The corner fit function is closely related to the 2D keystone function as both make 
adjustments to correct picture distortion. Therefore, when correcting picture distortion, 
both corner fit and 2D keystone functions should be used in conjunction to achieve the 
best picture shape.
To achieve the best picture shape:
• When installing the projector, align the projector to the screen so they are as 
perpendicular to each other as possible in order to minimize picture distortion.
• When making corner fit adjustments, if the desired effect cannot be achieved, adjust 
the 2D keystone value and try again.
• When making 2D keystone adjustments, if the desired effect cannot be achieved, adjust 
the corner fit value and try again.
