What to do if Furuno 1815 Marine Radar picture is not updated or freezes?
If your Furuno Marine Radar picture isn't updating or is freezing, check that the signal cables of bearing signal generator are fastened. If they are secured, replace the SPU board. Also, try turning the radar off and on again.
Why is Furuno 1815 not working correctly in true motion presentation?
If the true motion presentation on your Furuno Marine Radar isn't functioning correctly, check that the [Display Mode] in the [Display] menu is set to [True Motion]. Also, verify that the heading and position data are being input correctly.
What to do if Furuno Marine Radar set to maximum gain shows marks but no noise or echo?
If your Furuno Marine Radar displays marks and indications but no noise or echo when the gain is at maximum and sea clutter is at minimum, the problem could be with the signal cable, IF amplifier, or video amplifier board. Check the continuity and isolation of the coaxial cable. If the cable is good, replace the IF amplifier. Also, check the coax line for a secure connection; if the connection is good, replace the SPU board.
