5.3 Observation Environment and Image
Adjustment
5.3.1

Adjusting screen brightness

1
Adjust the screen brightness.
For the details of the adjustment, refer to "3.9 Adjusting the Brightness of the Screen and
Operation Unit". In consideration of the ambient brightness, adjust the brightness of the display
that is high enough to easily observe the radar display but does not glare.
5.3.2

Changing the observation range

1
Click on the [Range Scale] button in Range and mode information and select a range
from the context menu.
[Points on adjustments]
Increasing the observation range will enable a wider range to be observed.
However, a video image is small and the ability to detect targets near own ship decreases.
Therefore, when observing the vicinity of own ship, use the smaller observation range.
Decreasing the observation range will enable the vicinity of own ship to be enlarged. However,
caution must be taken because video images of the area beyond the observation range cannot
be displayed.
Since the image within the previous observation range is displayed by
expanding/contracting for the period from immediately after switching of the
observation range from the next image updating, do not use this image for
navigation.
If this image is used for navigation, an accident may occur.
Memo
An observation range under which the own ship display positon and the antenna position exceeds
the area 75% of the screen radius cannot be selected.
