You can also press Source on the projector or remote control to select your 
desired input signal. See 
 for details.
If no signal is detected for 3 minutes, the projector automatically enters ECO BLANK 
mode.
Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 1 quick-release adjuster foot and 1 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 
where you want it, 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 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.
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.
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 screen will be blank while Auto is 
functioning.
This function is only available when PC signal (analog RGB) is selected.
