Chapter 5 VARIOUS FUNCTION ICONS

＊＊＊＊
FOR REFERENCE＊＊＊＊
Trails REF Level
REF Level1 is the lowest level while “REF Level4” is the highest level. When radar
trails are plotted with unwanted waves, change to a higher level.
To thin radar trails, change to a higher level. If radar trails are plotted in snatches,
change to lower level.
Time/All Combine
This function superimpose-displays time radar trails and continuous radar trails.
When Time/All Combine Off is selected, this superimposed-display is disabled.
When Time/All Combine ON is selected, this superimposed-display is enable.
Trails Mode
True motion trails*:
The system plots the absolute motion trails of a target, irrespective of own
ship’s position. The operator can easily judge the course and speed of the
target. The system does not plot the trails of land and other fixed targets.
*True bearing signal input and speed signal input are required to display radar
trails in true trail mode.
Relative motion trails:
The system plots the trails of a target at a position relative to the own ship. The
operator can easily judge whether the target is approaching the own ship. While
the own ship is moving, the system also plots the trails when the own ship is
turning.
Trails Interval
Maximum value of radar trail display time.
Short: When short radar trails are often used in bays and the lakes.
Super Long: When long radar trails are necessary for ocean navigation.
Middle: Middle is for specification between Short and Long.
Continuous trails are available with all the options.
Short: Off/15sec/30sec/1min/2min/3min/4min/5min/6min/10min/15min/CONT
Middle: Off/30sec/1min/2min/3min/4min/5min/6min/10min/15min/30min/CONT
Long: Off/1min/2min/3min/4min/5min/6min/10min/15min/30min/1hour/CONT
Super Long: Off/30min/1hour/2hour/3hour/4hour/5hour/6hour/10hour/12hour/
24hour/CONT
