1.7 Degaussing the Screen
Each time the radar is turned on, the de-
gaussing circuit automatically demagnetizes
the CRT screen to eliminate color contami-
nation caused by earth’s magnetism or mag-
netized ship structure.
The screen is also degaussed automatically
at certain time intervals, which may be se-
lected on the menu. While being degaussed,
the screen may be disturbed momentarily
with vertical lines. If you wish to degauss by
manual operation, push the EBL rotary con-
trol (DEGAUSS control).
1.8 Initializing the Compass
Readout
With a compass interfaced with the radar,
ship’s heading is displayed at the top of the
screen. Upon turning on the radar, match the
on-screen HDG readout with the compass
reading by the procedure shown below. Once
you have set the initial heading correctly, re-
setting is not usually required. However, if the
HDG readout goes wrong for some reason,
repeat the procedure to correct it.
