REAL COLOR AND MONOCHROME 16 LCD PROJECTION PANELS
Projected characters or graphics
may appear to shimmer because of
differences in signal outputs of some
computers. Press the Sync+ button
until projected characters “lock” into
position and shimmering is
eliminated.
Each time Sync+ is pushed, it fine-
tunes the Projection Panel to match
signals from the graphics system.
Sync+
continuously cycles forward
through all 16 positions (press sync-
to cycle back to a good sync
position).

LEAR
Pressing the Clear button cleans any
unwanted random patterns that may
have appeared on the screen outside
the image area. In some cases,
positioning the image will leave a
trail of data. Use the Clear button
to remove this unwanted data.
You may also use this control to
blank the screen by clearing the test
pattern to all black or all yellow.
Disconnect the video signal to bring
up the test pattern and press Clear.
Background color depends on the
state of Reverse. Pressing Clear
again will restore the screen.
