摘要: A compact color monitor device that utilizes active and passive magnetic shielding to eliminate the visible distortion of color displays due to externally-imposed magnetic fields. The color monitor device can be installed in standard 19-inch EIA rack enclosures used on-board surface vessels and remain operable with no color distortion when the vessel is subjected to .+-.5 Oersted degaussing fields. The color monitor device includes a quick-degaussing circuit for degaussing internal components in approximately 1/60 of a second.
