Scanner Setup This menu item contains a sub-menu that enables you to adjust the settings for
the following functions:
•
Scanner Speed — this option is only available with scanners that support
multiple speeds.Two speeds are available — 24 RPM and Auto. You must
select the AUTO option if you want to use the 48 RPM scan speed.
• Tune Adjust — allows you to fine tune the radar scanner’s receiver for
maximum returns on the display. Raymarine recommends that this function is
set to AUTO. If you set this function to MANUAL and adjust the setting shortly
after powering up the radar scanner, you should adjust it again approximately
10 minutes after powering up the scanner, as the required setting will change
after the magnetron has warmed up.
• Sea Clutter Curve — radar echoes from waves can make it difficult to detect
real targets. These echoes are known as “sea clutter”. Several factors can
affect the level of clutter you see, including the weather and sea conditions,
and the mounting height of the radar. The sea clutter curve setting adjusts the
radar’s sensitivity to sea clutter. The steepest setting for the curve is 1, and
the most shallow setting is 8.
• Parking Offset (Digital only) — this setting is only available when the radar is
set to Off or Standby. The parking offset determines how the scanner is aligned
to the pedestal. The default setting is 0 degrees, with the scanner aligning to
the pedastal, facing forwards.
• Antenna Size — this is used to specify the size of your radar scanner.
