Chapter 8: Using the Radar (Digital) 185
Sea clutter curve
Radar echoes from waves around your boat can clutter the centre of the radar
picture, making it difficult to detect real targets. Several factors can effect the level
of clutter you see, such as the mounting height of the radar, weather and sea
conditions. The sea clutter curve settings adjust the system’s sensitivity to sea clutter.
The steepest setting is 1 and the shallowest is 8. The default setting is 1.
Parking offset
The default parking offset is 0 degrees: the scanner aligns with the pedestal, facing
forwards.
With parking offset selected you can use the rotary controller to adjust the parking
offset from 0 to 358 degrees in steps of two degrees.
This setting change is only available when the digital radar is set to Off or Standby.
The changes you make are applied at the end of the next transmit cycle.

Note:
Until you are familiar with interpreting the radar display, take every opportu-
nity to compare the radar display with your physical surroundings. Note the location
of boats, buoys and coastal structures and their corresponding echoes on the radar
display. Practice harbor and coastal navigation during daylight hours and in clear
weather conditions.
