Frequency (Data Only)
The L-1020 is automatically set to the optimum frequency
based on the detected data input signals. In some cases
however manual frequency adjustment may be required.
The
Frequency
adjustment acts as a horizontal size
control matching the clock frequency of the projector to
that of the computer. A misadjusted frequency will cause
evenly spaced dark vertical lines or distortions to appear
on the projected image. Use the slide rule control to
adjust the frequency until the lines spread apart and
finally disappear.
After you have completed the
Frequency
adjustment,
continue on to the
Tracking
adjustment described below.
Select
