How to fix incorrect orientation of picture on Furuno Marine Radar?
If the Furuno Marine Radar has incorrect orientation of picture, the HDG SIG MISSING message appears when the heading pulse is not received during transmitting. Also, replace the gyro interface.
How to display range rings on Furuno Marine Radar?
If the Furuno Marine Radar range rings are not displayed, try turning on the range rings with 0 RINGS in the MARK menu. If they still do not appear, their brilliance may be too low. Adjust their brilliance at page 1 of the BRILL menu.
Why Furuno Marine Radar antenna is not rotating?
If the Furuno Marine Radar antenna is not rotating, the antenna drive mechanism may need replacement. Alternatively, press the relay reset button, because there may be a defective antenna drive motor relay (thermal relay K2, 200/220/380, 440/100 VAC).
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.
What causes no noise or echo on Furuno Marine Radar?
If you adjust the GAIN with A/C SEA set at minimum on your Furuno Marine Radar and marks and indications appear but there is no noise or echo, the IF amplifier may need replacing. Check the continuity and isolation of the coaxial cable, disconnecting the plug and lugs at both ends before checking with an ohmmeter. Also check the video coax line for a secure connection; if the connection is good, replace the SPU board.
Why is Furuno Marine Radar picture not updating?
If your Furuno Marine Radar's picture is not updating or is frozen, it could be due to the bearing signal generator board (in the antenna unit). Check the connection of signal cables. Another potential cause is the SPU board, which may need to be replaced. Also, try turning the radar off and on again.
Why is my Furuno Marine Radar tuned but has poor sensitivity?
If the Furuno Marine Radar is properly tuned but has poor sensitivity, the magnetron may be deteriorated. Check the magnetron current with the radar transmitting on 48 nm range; if the current is below normal, replace the magnetron. The MIC may also be detuned and must be tuned. Additionally, ensure the radiator surface is clean and that there is no water in the feeder line. Finally, disable the second-trace echo rejector.
Why 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 and the transmission leak representing own ship position is absent, the TX high voltage protection circuit may have activated. Reset the power to restore normal operation. Alternatively, check the magnetron current and replace the magnetron if necessary. You may also need to replace the modulator board or the SPU board.
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 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.
