3.8.2.3 Trails Reduction
• Make a setting for thinning radar trails.
• The effect of thinning increases in order of   → → 
.
• Radar videos do not become obscure because of the thinning of radar trails.
 
3.8.2.4 Trails Process
• Determine whether to use the video process with radar signals for plotting 
radar trails.
• When Trails Process is   , radar trails are never plotted with unwanted 
waves, but the radar trails of moving targets may not be plotted.
• When Trails Process is   , radar trails may be plotted with unwanted 
waves, but the radar trails of moving targets are always plotted.
3.8.2.5 MAX Interval
• Select the maximum time for displaying radar trails.
• Select   when short radar trails are often used in bays and the likes.
• Select   when long radar trails are necessary for ocean navigation.
