OPERATION
FREQ
•
With data from a source displayed on-screen, set the
background to a chequered pattern 50% grey (direct
mode 1:1 uncompressed).
•
If the frequency is set wrongly, vertical unstable
bands will be visible in the image (see illustration).
•
Adjust with the frequency right/left keys to remove all
the vertical bands (see illustration).
TUNE
•
Adjust the tuning up/down keys to stabilize the
image. Preferably all the “sideways swimming” lines
should be removed (see illustration).
SCALE
•
If your computer screen resolution is not exactly
800x600, select SCALE. This will scale the source
resolution to fit the LCD screen resolution by
adjusting the number of vertical and horizontal pixel
lines at intervals throughout the image.
