Kathryn DeanAug 22, 2025
If the range on your Furuno Marine Radar is changed but the picture isn't updating, try adjusting the range using the control unit or the [RANGE] box several times. If this doesn't work, power cycle the radar to resolve potential video freeze-up. If the issue persists, the keypad may need to be replaced.

Why Furuno FAR-1513 Marine Radar has poor sensitivity when tuned properly?

Michael CrossSep 2, 2025
If your Furuno Marine Radar is properly tuned but has poor sensitivity, possible causes include a deteriorated magnetron, a detuned MIC, dirt on the radiator face, water ingress to the waveguide or other feeder line, or the second trace echo rejection being ON. With the radar transmitting on 48 nm range, check the magnetron current and replace if below normal. Check the MIC detecting current and tune if necessary. Clean the radiator surface, remove water from the feeder line, and disable the second-trace echo rejector.

If marks, indications, and noise appear on your Furuno Marine Radar but there is no echo, and the transmission leak representing your own ship's position is absent, it could be due to several reasons. The TX high voltage protection circuit may have activated (reset power to restore normal operation), the magnetron may be faulty (check magnetron current and replace if necessary), the modulator board may need replacement, or the SPU board may be the issue (replace SPU board).

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.

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.

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.

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-1513 Marine Radar cannot turn on?

Mr. Victor MaddoxAug 25, 2025
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.
