2.1) Menu Item “Load Default Error list“
By pressing “Load Default Error list“ the neutral or factoryside error table will be activated
and stored. The actual error table will be deleted!
Accept safety warning by striking “Menu/Enter“ button. Cancel by “Back To Operation“.
During restorage do not strike any further key!
2.2) Menu Item “Set Up Error list“
Adjust the traditional magnetic compass before correction of transmission error!
Transmission error is the difference of the direct reading of the magnetic compass and the heading
as displayed by NETcourse. This Menu item enables you to establish a errorlist. This is only
necessary in case too large transmission errors are recognized. These transmission errors are caused
by the direct interference of the corrector magnets to the detector, so these errors are not a
malfunction of the instrument but they result from the ship´s magnetic iron resp. their correction!
After activating this Menu item the display shows 0°, the first reference heading to establish
errorlist. Steer the ship into magnetic heading 0° (it is wrong to take out only the compass itself
from its suspension and rotate it into direction 0°). Accept this setting by “Menu/Enter“ push
button. The NETcourse display now proceeds to 15°. Steer the ship into magnetic heading 15° and
accept the setting same as above by actuating “Menu/Enter“ button. This way complete a total
swing of 360° for each reference heading of 15°. It is not necessary to follow each point of the
sequence of reference points. This Menu item also allows to select one of the reference headings
(0°, 15°, 30°, 45° ....) individually. To choose the required reference heading use the “Up/Down“
push button and activate setting by pushing „Menu/Enter“ button. It is not necessary to pass all
reference headings, each heading can be changed individually.
