How to troubleshoot power issues on Furuno Marine Radar?
If you cannot turn on the power to your Furuno Marine Radar, check for a blown fuse. Also, check that the power connector is fastened, look for corrosion on the power cable connector, and inspect the power cable for damage. Finally, check the battery for correct voltage output.
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.
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 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.
What to do if a key is not responding on Furuno 1815 Marine Radar?
If there is no response when a key is pressed on your Furuno Marine Radar, turn the power off and on. If you still do not get a response, the key may be damaged.
How to improve target tracking on Furuno 1815?
If a target is not tracked correctly on your Furuno Marine Radar because of sea clutter, adjust the sea clutter and rain clutter settings.
What to do if my Furuno 1815 Marine Radar shows noise but no echoes?
If your Furuno Marine Radar shows marks, indications, and noise but no echoes, select the maximum range and check the magnetron current. If the current is below the rated value, replace the magnetron. If that doesn't resolve the problem, the MD-PWR Board or IF-SPU board may need to be replaced.
How to fix a frozen picture on my Furuno 1815 Marine Radar?
If the Furuno Marine Radar picture has frozen, check the connection between the IF-SPU board and the heading sensor inside the antenna unit. If the connection is good, the MAIN board may need to be replaced. You can also try turning the radar off and on again.
What to do if Furuno Marine Radar data and marks are not displayed in transmit?
If data and marks are not being displayed during transmission on your Furuno Marine Radar, the issue may stem from the SPU board. Replacing the SPU board should rectify this.
What to do if Furuno Marine Radar brilliance adjusted but no picture?
If you've adjusted the brilliance on your Furuno Marine Radar but there's still no picture, the issue may be with the SPU board. In this case, replace the SPU board.
