CHAPTER 4: Operation
NOTE
The Projection Panel must
be placed correctly on the
overhead projector. Incorrect
placement may cause the
Projection Panel to project
blurry or mis-converged
images. For more infor-
mation, see Appendix A.
4. Press Sync until the image is
locked in as a solid image with
no shimmer or movement. This
button toggles through the
present settings to the specific
computer graphics type. Press
Sync
until you achieve the best
image.
5. For VGA, MCGA, and Macintosh
II, you may need to hold down
Shift
and press Level Up or
Level Down to choose the best
color matching. For best results
when adjusting the level, display
an image that has a wide range
of colors.
For VGA text display, you may
need to adjust the Text Mode if
the text characters are jagged or
shimmering.
6. If your computer is one of the
standard supported systems,
your image should be fully
adjusted at this point. However,
if your computer is any other
type, you may see evenly spaced
fuzzy vertical lines, or text may
appear to be too wide or too
narrow for the screen. To
correct this problem, go to the
User Menu (press the Menu
control button) and adjust the
tracking.
7. You may want to press Reverse
to select either light characters
on a dark background or dark
characters on a light
background. Use the setting
which best suits your graphics or
text.
8. To restore factory-set default
values, hold down Shift and
press Reset while the menu is
being displayed.
4.5 User Menu
Pressing the Menu control button
displays the User Menu on your
computer’s monitor. The User
Menu allows you to change the color
balance, adjust the tracking, and
control how information is
displayed.
