What to do if Furuno 1815 Marine Radar range rings are not displayed?
If the range rings are not displayed on your Furuno Marine Radar, first adjust their brilliance on the [Brill/Color] menu. If this does not solve the problem, replace the associated circuit board.
How to fix Furuno Marine Radar when you cannot turn on the power?
If you're unable to turn on your Furuno Marine Radar, check the following: • Check for a blown fuse. • Ensure the power connector is securely fastened. • Inspect the power cable connector for corrosion. • Check for any damage to the power cable. • Verify the battery provides the correct voltage output.
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.
Why Furuno 1815 antenna not rotating?
If the antenna on your Furuno Marine Radar isn't rotating, the problem likely lies within the antenna drive mechanism. Replacing the antenna drive mechanism should resolve this issue.
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.
How to fix Furuno 1815 Marine Radar target tracking issues caused by sea clutter?
To address incorrect target tracking on your Furuno Marine Radar due to sea clutter, adjust the sea clutter and rain clutter settings.
What to do if Furuno 1815 shows marks but no echo?
If your Furuno Marine Radar displays marks, indications, and noise but no echo, and the transmission leak representing your ship's position is absent, the issue might be with the magnetron, modulator board, or SPU board. Check the magnetron current. If that's not the problem, replace the modulator board. If the issue continues, replace the SPU board.
What causes poor sensitivity in Furuno Marine Radar even when correctly tuned?
If your Furuno Marine Radar has poor sensitivity despite correct tuning, the possible causes are dirt on the radiator face, a deteriorated magnetron, or a detuned MIC. Clean the radiator. Check the magnetron current with the radar transmitting on 48 nm range; if the current is below normal, the magnetron may be defective and needs replacement. Also, check the MIC detecting current; if it's below the normal value, the MIC may have become detuned.
Why Furuno 1815 range rings are not displayed?
If the range rings are not showing on your Furuno Marine Radar, check that the setting of [Rings Brill] in the [Brill/Color] menu is set to other than [Off].
What to do if Furuno 1815 range is changed but radar picture does not change?
If changing the range on your Furuno Marine Radar doesn't alter the radar picture, try changing the range again. If the issue persists, turn the display unit off and on.
