Radar Setup

The Radar Setup menu allows you to setup and adjust radar settings,
like Transmit Off Zone and Antenna Park. Most of the settings in the
Radar Setup menu will only have to be set once, but we recommend you
check the settings periodically for general maintenance.
NOTE:
Before starting radar setup, take your vessel out on open water
with fairly calm seas, like an open bay.
The three setup features we want to modify are Adjust Trigger Delay,
Adjust Main Bang Suppression and Adjust Heading Line.
We will set them up in that order, but before making any adjustments,
make sure the display is set to a range of 1/8 nautical miles and that
Gain, Anti-Sea Clutter (STC), Anti-Rain Clutter (FTC), Main Bang
Suppression and Trigger Delay all have been set to zero percent.
