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.
