or piers having curves or an indentation. Objects close to your vessel may appear "pulled in"
or "pushed out".
Adjust the range offset as below when the vessel is about 45 to 90 m (50 to 100 yards) from a
straight-walled jetty or similar feature that produces a straight line echo on the display.
• Point the boat towards the jetty
• Adjust the gain setting until a reasonably good image of the jetty echo is displayed
With the Range offset dialog open:
• Turn the rotary knob to adjust the range offset to make the jetty echo appear as a straight
line on the display
• Press the ENT key to save the settings

Adjust bearing alignment
This is to align the heading marker on the screen with the center line of the vessel. This
setting compensates for any slight misalignment of the up-mast transceiver during
installation. Misalignment that is not corrected for will compromise target tracking and can
result in dangerous misinterpretation of potential navigation hazards.
Point the vessel towards a stationary isolated object. Then with the Bearing alignment dialog
open:
• Press the rotary knob to switch focus between coarse and fine bearing alignment
• Turn the rotary knob to adjust the bearing alignment so that the heading line touches the
end of the selected stationary object
• Press the ENT key to save the settings and close the Bearing alignment dialog
Sector blanking
If the radar is installed in close proximity to a mast or structure, that could cause unwanted
reflections or interference to appear on the radar image. Use the sector blanking feature to
stop the radar from transmitting in the direction up to four sectors.
Note:
Sectors are setup relative to the heading line of the radar. The bearing of the
sector is measured from the front of the vessel to the center line of the sector.
Sidelobe suppression
Occasionally false target returns can occur adjacent to strong target returns such as large
ships or container ports. This occurs because not all of the transmitted radar energy can be
