1.7 Degaussing the CRT
Screen
Each time the radar is turned on, the de-
gaussing circuit automatically demagne-
tizes the CRT screen to eliminate color
contamination caused by earth's magne-
tism or magnetized ship structure.
The screen is also degaussed automati-
cally when own ship has made a signifi-
cant course change. While being
degaussed, the screen may be disturbed
momentarily with vertical lines. If you wish
to degauss by manual operation at an
arbitrary time, open and press the "DE-
GAUSS" switch.
