Operation 25

You can also press Source on the projector or remote control to select your 
desired input signal. See 

 for details.

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.

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.
