1. Set Radar range to between 1/2 nm to 1 nm and Sidelobe
Suppression to Auto
2. Take the vessel to a location where sidelobe returns are likely to
be seen. Typically, this would be near a large ship, container
port, or metal bridge.
3. Traverse the area until the strongest sidelobe returns are seen.
4. Change Auto sidelobe suppression to OFF then select and
adjust the sidelobe suppression control until the sidelobe
returns are just eliminated. You may need to monitor 5-10 radar
sweeps to be sure they have been eliminated.
5. Traverse the area again and readjust if sidelobes returns still
occur.
6. Exit the dialog.
Adjust local interference reject
Interference from some onboard sources can interfere with the
Broadband radar. One symptom of this could be a large target on
the screen that remains in the same relative bearing even if the
vessel changes direction.
Choose from Local interference rejection LOW, MED or HIGH.
Default is LOW.
Restore radar to factory defaults
This option can be used to revert all user adjustments.
