projected image becomes trapezoidal. You can adjust the
adjuster feet to fine-tune the horizontal angle.
To retract the feet, screw the adjuster feet in a reverse
direction.

AUTO
. 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.
Do not look into the lens while the lamp is on. The strong light from the lamp may cause damage to your eyes.
