What to do if Furuno FAR-1518 Marine Radar power is on but nothing appears on monitor?
If the power is on but nothing appears on the monitor of your Furuno Marine Radar, the brilliance may be too low. Adjust the brilliance.
Why Furuno Marine Radar cannot turn on?
If your Furuno Marine Radar cannot be turned on, the cause may be a blown fuse, incorrect mains voltage/polarity, or a faulty power supply board. To resolve this, replace the blown fuse, correct the wiring and input voltage, or replace the power supply board.
What to do if Furuno FAR-1518 Marine Radar picture not updated?
If the picture on your Furuno Marine Radar is not updating or is frozen, this is likely due to a video freeze. Turn the power off and on again to restore normal operation.
Why Furuno Marine Radar shows marks and noise but no echo?
If you see marks, indications, and noise but no echo on your Furuno Marine Radar, the Tx high voltage protection circuit may have been activated. Reset the power to restore normal operation.
How to fix Furuno Marine Radar when range changed but picture not changing?
If the range is changed on the Furuno Marine Radar but the picture is not changing, it could be due to a defective range key, a faulty SPU board, or a video freeze-up. Try adjusting the range with the control unit or the [RANGE] box several times; if that doesn't work, the keypad may need replacement. If still not working, replace the SPU board. Alternatively, try turning the radar off and on.
How to fix Furuno Marine Radar antenna not rotating?
If the antenna on your Furuno Marine Radar is not rotating, it could be due to the antenna drive mechanism or a defective antenna drive motor relay. To fix this, replace the antenna drive mechanism or press the relay reset button.
Why Furuno FAR-1518 Marine Radar has poor discrimination in range?
Poor discrimination in range on your Furuno Marine Radar can be caused by the sea clutter control not functioning properly. This can be due to an improper setting of A/C SEA. If A/C SEA is seen only at very close range, suspect inaccurate frequency of reference oscillator.
How to fix Furuno Marine Radar picture not updating?
If the picture on your Furuno Marine Radar is not updating or is frozen, it could be due to the bearing signal generator board (in the antenna unit), the SPU board, or a video freeze-up. Check the connection of signal cables. Replace the SPU board. Turn the radar off, then on.
Why Furuno Marine Radar shows marks but no noise when GAIN adjusted?
If, with the GAIN adjusted and A/C SEA set to minimum, marks and indications appear on your Furuno Marine Radar but there is no noise or echo, it could be due to the IF amplifier, the signal cable between the antenna and processor unit, or the video amplifier board. Replace the IF amplifier. Check the continuity and isolation of the coaxial cable (disconnect the plug and lugs at both ends before checking with an ohmmeter). Check the video coax line for a secure connection; if the connection is good, replace the SPU board.
Why Furuno FAR-1518 Marine Radar picture is not updated with each sweep?
If the picture on your Furuno Marine Radar is not updating with each sweep, it could be due to slots in the rotating disc in the antenna unit or the motor brushes. Remove any foreign material (carbon, grease, etc.) from the slots. If the motor brushes are shorter than 6 - 7 mm, replace them.
