How to fix Furuno FAR-1523-BB showing only two PI lines?
If your Furuno Marine Radar is only showing two PI lines when six are desired, it is likely due to an incorrect setting of the PI line interval or an inappropriate setting for the number of PI lines to display. Adjust the PI line interval. Also, check the menu setting for the number of PI lines.
Why Furuno FAR-1523-BB 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-1523-BB 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 FAR-1523-BB 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.
Why Furuno FAR-1523-BB Marine Radar interference rejector is inoperative?
If the interference rejector on your Furuno Marine Radar is inoperative and the interference rejection level is not displayed, the issue is likely with the SPU board. Replace the SPU board.
How to fix Furuno FAR-1523-BB target not tracked correctly?
If a target is not being tracked correctly on your Furuno Marine Radar, it may be due to poor definition of targets in sea clutter. Adjust A/C SEA and A/C RAIN.
Why cannot operate Furuno FAR-1523-BB Marine Radar from on-screen boxes?
If you cannot operate the radar from the on-screen boxes on your Furuno Marine Radar, the issue is likely with the SPU board. Replace the SPU board.
Why Furuno FAR-1523-BB 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-1523-BB 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.
