Operation 21
Adjusting the image
Adjusting the height
Place your projector on a flat level surface and ensure that the projector is square to the
screen.
The projector is equipped with 2 quick-release adjuster feet. These adjusters change the
image height and projection angle. To adjust the projector,
1. Lift the projector up and press the
adjuster button to release the
adjuster. The adjuster will drop
into position and be locked.
Do not look into the lens while the lamp
is on. The strong light from the lamp
may cause damage to your eyes or sight.
2. Screw the rear adjuster feet to
fine-tune the projection angle.
To retract the foot, press the adjuster button
again.
If the screen and the projector are not
perpendicular to each other, the projected
image becomes vertically trapezoidal. To
correct this situation, adjust the value of
Keystone in the Display menu, on the
projector control panel or on the remote
control.
Auto-adjusting the image
In some cases, you may need to optimize the picture
quality. To do this, press Auto on the control panel of
the projector or on the 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.
