Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 1 quick-release adjuster foot and 2 rear adjuster feet. 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 where you want it, release the 
quick-release button to lock the foot in 
position.
2.
Screw the rear adjuster feet 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 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 
 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.
• 
The screen will be blank while AUTO is functioning.
• 
This function is only available when PC signal (analog RGB) is selected.

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.
Sharpen the image by rotating the focus ring.
