2.  RADAR, CHART RADAR OPERATION

1) Set the radar settings as follows:

2) Adjust the gain so that a slight amount of white noise appears on the screen. 

Arcs for the performance monitor appear on the screen.

3) Set [PM GAIN ADJ] so that the outer arc faintly appears. The setting range is 

0 to 255. Wait at least eight scans then adjust. The following illustration is an 
example when [ARC] is set to [5] (see "How to set the number of arcs" on 
page 2-49).

Note: The location of the arcs changes with the setting of [ARC].

7. Close the menu.

The reference position for measurements (range, bearing, etc.) and markers (heading 
line, stern mark, etc.) can be the antenna position or CCRP, which is a location on own 
ship to which all horizontal measurements, for example range, bearing, relative 
course, relative speed, closest point of approach (CPA) or time to closest point of ap-
proach (TCPA), are normally referenced. 

To select the reference position, click the button below [REF point] at the top-left po-
sition to select [ANT] or [CCRP] as appropriate.

The position of the own ship marker changes according to reference position as 
above. If the CCRP is positioned outside of the effective display area, the bearing 
scale is indicated with the appropriate reduced detail.
