Board.
5. Turn the ON/OFF brightness control on the front of the unit all the way counter-clockwise to the
dimmest setting. Adjust the potentiometer marked "DIM" until the screen is just visible in near
darkness.
6. Turn the ON/OFF brightness control all the way clockwise to the brightest setting. Adjust the
potentiometer marked "BRIGHT" until the disclaimer page is readable in direct sunlight without
having the image "bloom" or expand.
Adjust Linearity
7. Locate the adjustment in Figure 16 marked "VERT. LIN" in Figure 16. (This adjustment is needed
if circles on the screen appear distorted.) Adjust in small increments using a very fine screwdriver.
Adjust Horizontal Size
8. Because the Argus screen most closely resembles a television on its side, the horizontal (side to side)
size is controlled by the potentiometer marked "VERT. SIZE." Adjust in small increments using
a very fine screwdriver.
Adjust Focus
9. Locate the adjustment in Figure 16 marked "FOCUS." Use a very fine screwdriver to first turn the
adjustment counter-clockwise. (That is the more common direction for this adjustment.) If
necessary, turn the adjustment in a clockwise direction. Adjust until the image on the screen is the
sharpest.
Replace Panel
10. After making necessary adjustments, turn the unit off and disconnect it from the power source.
11. Replace the panel and secure it in place with the appropriate screws.
