Description
This menu item contains a sub-menu that enables you to adjust
the timed transmit options:
• Timed Transmit
• Transmit Period
• Standby Period
This menu item 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.
The measurement point used for reference when measuring
distances using Electronic Bearing Lines (EBLs) and range
rings in the chart application. The options are Relative to ships
heading or referenced to the compass is degrees Magnetic —
True as selected in Bearing Mode.
This menu item allows you to adjust the Sea Clutter — 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.
