Proper setting of radar display

​Normally the auto features will work well for most situations. If you want to adjust the radar manually try the following:
 
1. Transmit the radar in maximum range
 
2. Set STC (sea clutter) to minimum
 
3. Set FTC (rain clutter) to minimum
 
4. Set the gain control to maximum (the screen should show mostly radar noise)
 
5. Now adjust the gain control to show a very small amount of noise (only a few noise spots on the screen)
 
6. Without disturbing the gain control select the appropriate working range
 
7. Adjust STC(sea clutter) as desired
 
8. Adjust FTC(rain clutter) if needed
 
Note: The timing and heading must still be set according to the procedure listed in the installation manual.
