[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.

If a target under tracking goes into a range over 32 NM and can no longer be tracked, it is canceled without a lost target notification being issued.

The past position is set. [Off] : Tracks are not displayed. [Numeric] : Tracks are displayed at intervals of the specified value. The past position function can display up to ten past positions of a target under tracking. The past position display interval can be set to specified time intervals of 0.5, 1, 2, or 4 minutes, or specified range intervals of 0.1, 0.2, 0.5, or 1 NM. When [Off] is displayed, the track display function is turned off. The track mode operates in conjunction with the vector mode, and a true or relative track is displayed. In relative vector mode, the relative tracks of the target are displayed. In true vector mode, true tracks that are calculated from the relative bearing, range, own ship's course, and speed are displayed. Note When the target is acquired, past position of traced target is start plot. When the AIS target is displayed, past position of AIS target is start plot. If the past position plotted time or range is short, the indicated past position duration may not have achieved the specified time or range. 6.8.2 Setting the other ship's tracks This function makes settings for the tracks of tracked targets and AIS targets.
