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 Presentation and mode information, and then
select Range from the pop-up menu.
Range Scale button
[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.
