Why Furuno Marine Radar has poor discrimination in range?
If the Furuno Marine Radar has poor discrimination in range, the sea clutter control may not be functioning properly. This could 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.
Why Furuno Marine Radar range rings are not displayed?
If the Furuno Marine Radar range rings are not displayed, adjust the brilliance of range rings on the BRILL menu to see if intensity is increased. If unsuccessful, replace associated circuit board. Alternatively, replace the SPU board.
How to fix Furuno Marine Radar when nothing appears on the monitor?
If the Furuno Marine Radar power is on but nothing appears on the monitor, the brilliance may be too low. For keyboard-type control units, turn the BRILL control clockwise to increase the brilliance. If you have a trackball-type control unit, press any one of F1-F4 for five seconds to increase the brilliance to '50'.
What to do if Furuno Marine Radar picture freezes?
If the Furuno Marine Radar picture is not updated or freezes, turn the power off and on again to restore normal operation. Thirty seconds after the picture freezes, the buzzer sounds, the [ALARM ACK] key blinks and alarm signal is output.
What to do if marks appear but no echo on Furuno Marine Radar?
If marks, indications, and noise appear on your Furuno Marine Radar but there is no echo, the Tx high voltage protection circuit may have activated. Reset the power to restore normal operation.
What to do if buttons on trackball module operated but no response on Furuno Marine Radar?
If the Furuno Marine Radar buttons on the trackball module are operated but there is no response, replace the trackball module.
Why is interference rejector inoperative on Furuno Marine Radar?
If the Furuno Marine Radar interference rejector is inoperative (interference rejection level not displayed), replace the SPU board.
Why is echo stretch ineffective on Furuno Marine Radar?
If the Furuno Marine Radar echo stretch is ineffective (neither ES1, ES2 nor ES3 is displayed), replace the SPU board.
How to fix Furuno Marine Radar when target is not tracked correctly?
If the Furuno Marine Radar tracked target is not tracked correctly, adjust A/C SEA and A/C RAIN controls.
What to do if Furuno Marine Radar does not operate at all?
If the Furuno Marine Radar is not operating at all after being turned on, the fuse may be blown, the mains voltage/polarity may be incorrect or there may be a problem with the power supply board. Replace the blown fuse. Correct the wiring and input voltage. Replace the power supply board.
