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.
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.
Fine-tuning the image clarity
If needed, sharpen the picture by rotating the focus ring.
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.
