usually appears as a spiral of small dots from the display centre
This type of interference is most noticeable at long ranges.
This interference can be suppressed using the interference
rejection settings. The images in the table below show how
the Interference rejection settings can clear up some of this

Additional functionality of the radar application includes:
• Color palettes.
• Adding AIS overlay.
• MARPA targets.

Typically, your vessel's position is at the center of the display,
and its dead ahead bearing is indicated by a vertical heading
line, known as the Ship's Heading Marker (SHM).
Note: If the cursor is placed over the SHM, the SHM will
temporarily be removed to help placing markers or acquiring
targets etc.
On-screen targets may be large, small, bright or faint, depending
on the size of the object, its orientation and surface. If using
a non-HD digital radome scanner, strongest target returns are
displayed in yellow with weaker returns in 2 shades of blue. If
using a HD or SuperHD radar scanner, stronger target returns
show as different colors from a range of 256 colors, providing
better clarity. Be aware that the size of a target on screen
