Degaussing your Monitor
If your monitor is displaying “purity problems,” (a display with purity problems will have parts of an all-
white screen affected by blotches of color) the monitor needs to be degaussed using a “degaussing coil.”
A degaussing coil is a circular electromagnet, used to cancel out any stray magnetic fields that may build
up on a metal object.
All of our monitors have built-in degaussing coils that are automatically activated on power-up. If your
game is experiencing minor purity problems, try powering down the game for 5 minutes and then
reapplying power to activate the degaussing coil. If the problem is not corrected, you will have to use a
manual degaussing coil.
Follow the instructions below for degaussing a monitor.
1. Plug in your degaussing coil.
2. Hold the coil about three feet from the monitor, press the trigger to activate the magnetic field (for
circular-shaped coils, orient the coil so you see the monitor through the hole in the middle; for wand-
shaped coils, point the wand towards the screen).
3. Move the coil in a circular motion around the face of the monitor and slowly approach the game.
4. Continuing to move the coil in a circular motion, slowly back away from the monitor.
5a. CIRCULAR-SHAPED COILS: When you are about three feet away, quickly turn the coil perpendicular
to the monitor and release the trigger.
5b. WAND-SHAPED COILS: When you are about three feet away, point the wand away from the monitor
and release the trigger.
Monitor Colors Adjustment Procedure
For adjusting the colors on any of our monitor types, we suggest following the procedures described
below.
The vertical/horizontal controls and brightness/contrast controls are located on the monitor control panel,
Velcroed inside the game. The monitor RGB controls are located on the monitor neckboard. Adjust the
RGB controls until the screens look as suggested in the following steps.
Ducksan/Telco/Tatung Monitors
1. Set the game to the Run 21 game screen.
2. Adjust the vertical and horizontal size and vertical and horizontal position to make sure that the game
screen fills the monitor screen and that the game screen is centered.
3. Adjust the brightness and contrast controls until the playing cards are a light, ivory color. (Adjusting
the brightness and contrast can also correct for a lack of sharpness in the picture.)
4. Exit Run 21 and enter the Hoop Jones game screen. Make sure that the court surface is greenish in
color and look for a clean, white border around the number on the player’s jersey.
5. Exit Hoop Jones and enter the Great Solitaire game screen. Make sure that the game background is
a light, greenish-gray (may be bluish-gray for Tatung monitors).
