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 monitor unit.
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)
Pressing the [RANGE+] key will increase the observation range,
enabling the wider area to be observed.
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)
Pressing the [RANGE-] key will decrease the observation range,
reducing the area that can be observed.
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.
