OBSERVE AND ADJUST VIDEO
3.2.1 Adjust Monitor Brilliance [BRILL]
Procedures 1 Obtain the best-to-see display with optimum brilliance by turning the
[BRILL] dial at the lower right of the LCD monitor.
Turning the
[BRILL] dial clockwise increases the brilliance of the entire display.
Conversely, turning the [BRILL] dial counterclockwise decreases the brilliance of the
entire display.
In consideration of the ambient brightness, adjust display brilliance that is high
enough to easily observe the radar display but does not glare.
3.2.2 Change Observation Range [RANGE + / - ]
Procedures 1 When increasing the observation range, press the [RANGE+] key.
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.
2 When decreasing the observation range, press the [RANGE-] key.
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.
