Operations
Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 2 adjuster feet. These adjusters change the image height and
projection angle. To adjust the projector:
Screw adjuster foot to ne tune the horizontal
angle.
To retract the foot, hold up the projector then
slowly lower the projector. Screw the adjuster
foot in a reverse direction.
If the projector is not placed on a at surface
or the screen and the projector are not
perpendicular to each other, the projected image
becomes trapezoidal. To correct this situation,
see "Correcting 2D Keystone" on page 27 for
details.
• Do not look into the lens while the projector is on. The strong light from the light 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 current source information will be displayed in the upper left corner of the screen for 3
seconds.
• The screen will be blank while AUTO is functioning.
• This function is only available when PC signal (analog RGB) is selected.
Fine-tuning the image size and
clarity
Sharpen the image by rotating the FOCUS ring.
