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

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.

1. Go to System Setup : Advanced > Password
 to display the Password window.
2. Select Change Password and press OK to display the Input Password window.

as ****** when you enter them.
4. Re-enter the same password to verify and return to the Password window.

Selecting an input source
The projector can be connected to multiple equipment at the same time. However, it only displays one

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 43)
• 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 32 and 34)
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.

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 projector:
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. 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, turn the zoom ring on the projector. 
To sharpen the picture, rotate the focus ring on the projector.
Do not look into the lens while 
the lamp is on. The strong light 
from the lamp may cause 
damage to your eyes.
