Securing the projector
Using a security cable lock
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 
26 on page 8 for details. 
A Kensington security cable lock is usually a combination of key(s) and the lock. Refer to the locks 
documentation to learn how to use it.
Utilizing the password function
For security purposes and to prevent unauthorized use, you may set up password security via the On-
Screen Display (OSD) menu. Once the password is set and the function is enabled, the projector is 
password-protected. Users who do not know the correct password may not use the projector.
You will be inconvenienced if you enable the password function yet forget the password somehow. Do make a 
note of your password, and keep the note in a safe place for later recall.

as ****** when you enter them.
4. Re-enter the same password to verify and return to the Password window.
5. Select Pow e r  O n  L o c k and use  /  to set On.
6. Enter the current password to enable the function.

projector. Once you enter an incorrect password, the error message displays, and the Input Password 
window follows. 
You can retry by entering another six-digit password, or if you absolutely do not remember it, use the 
password recall procedure. See Entering the password recall procedure for details.

Selecting an input source
The projector can be connected to multiple equipment at the same time. However, it only displays one 
full screen at a time. When starting up, the projector automatically searches for the available signals.
If you want the projector to always automatically search for the signals:
• Under the Advanced OSD menu, go to the System Setup : Basic menu, and enable Auto 
Source. (see Auto Source on page 41)
• Under the Basic OSD menu, if there’s no signal connected to the projector, go to Auto Source and 
enable it; if there are signals connected, go to the Settings menu, and then enable Auto Source. 
(see Auto Source on page 30 and 32)
To select the video source:
1. Press SOURCE on the projector or remote control to display the source selection bar.

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 Aspect Ratio for details.

  Operation
Adjusting the projected image
Adjusting the projection angle 
The projector is equipped with a quick-release adjuster foot 
and a rear adjuster foot. These adjusters change the image 
height and projection angle. 
To adjust the projection angle:
1. Press the quick-release button and lift the front of the 
projector. Once the image is positioned as desired, release 
the quick-release button to lock the foot in position.
2. Screw the rear adjuster foot to fine-tune the horizontal 
angle.
To retract the foot, hold up the projector while pressing the 
quick-release button, then slowly lower the projector. Screw 
the rear adjuster foot in a reverse direction.
If the screen and the projector are not perpendicular to each 
other, the projected image becomes vertical trapezoidal. To 
correct this, see Auto-adjusting the image for details.
Auto-adjusting the image
In some cases, you may wish to optimize the picture quality of PC signal. 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 input source information will be displayed in the corner of the screen for 3 seconds.
This function is only available when PC signal is selected.
Fine-tuning the image size and clarity
•  To adjust the projected picture size:
i. Slide off the lens compartment cover 
(see item 6 on page 8). 
ii. Turn the zoom ring to zoom in or 
zoom out.
iii. Slide in the lens compartment cover 
when you complete the adjustments.
•  To sharpen the picture:
i. Slide off the lens compartment cover 
(see item 6 on page 8). 
ii. Rotate the focus ring to achieve a 
sharper focus.
iii. Slide in the lens compartment cover 
when you complete the adjustments.
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.

picture type.
The preset picture modes are described as 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.
• Vivid: Being slightly brighter than Cinema mode, it is suitable for playing 
movies in rooms where there is a small amount of ambient light, eg. your living 
room.
• Cinema: With well-balanced color saturation and contrast with a low 
brightness level, this is most suitable for enjoying movies in a totally dark 
environment (as you would find in a commercial cinema). 
• Game: This mode is best for playing video games in rooms where there is a 
small amount of ambient light, eg. your living room.
• 3D: Optimized to bring up 3D effects when watching 3D contents.
This mode is only available when 3D function is enabled.
• User 1/User 2: Recalls the customized settings. Access the Advanced OSD

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.  
The default setting is Auto and the projector automatically chooses an appropriate 
3D format when detecting 3D contents. If the projector cannot recognize the 3D 
format, manually choose a 3D mode according to your preference.
When this function is enabled:
• The brightness level of the projected image decreases.
• The Picture Mode cannot be adjusted.
• The Vertical Keystone can only be adjusted within limited degrees.
