[6]  Process Switch Range 
 
•  Set the boundary range of a specific area. 
•  This function is enabled when    Range Fix    is selected in [4] Process Switch. 
•  The specific area turns out to be a circle with the own ship’s position as the center. 
•  The boundary range can be set in units of 0.1 nm, ranging 0.1 to 25.5 nm. 
 
 
[7]  Fast Target Detection 
 
•  This function displays fast moving targets that are suppressed in scan-correlative process mode. 
•  This function is enabled when    3Scan CORREL ,    4Scan CORREL , or    5Scan CORREL    is 
selected as the video process mode. 
•  If unwanted waves remain of the display, suppress them by using the [SEA], [RAIN], or [GAIN] 
dial, or adjusting the interference rejection mode. 
  Off    : Disables the Fast Target Detection function. 
  On    : Enables the Fast Target Detection function. 
 
 
 
 
 
3.8.2  Set Radar Trails (RADAR Trails Setting) 
 
This function enables the setting of detail information about radar trails processing. 
 
 
 Procedures   1  Press the [TRAILS] key for 2 seconds. 
 
The RADAR Trails Setting menu will appear. 
Detail data about radar trails processing can be set by changing the settings of each 
menu item. 
 
 
Note:  After the settings for radar trails processing are changed, targets’ trails may not be displayed or 
trails may be plotted with unwanted waves.    Thus, do not make a significant change in the 
settings. 
 
 
 
[1] Trails Mode 
 
•  Set the radar trail display mode. 
•  For details on the trail mode, see Section 3.4.8. 
 
 
[2]  Trails Reference Level 
 
•  Select a radar video threshold level required for plott n
•  The radar video threshold level increases in order of   
i g radar trails. 
 Level1  → Level2  → Level3  → Level4 . 
•  To plot radar trails 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 a lower level.
