If no signal is detected for 3 minutes, the projector automatically enters ECO BLANK

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 "Magnifying and searching for details" 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
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.
