Operation

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 "Correcting keystone" on page 33 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 Adjusent

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.
