- DDaniel HallSep 23, 2025
If a target is not being tracked correctly, adjust the A/C SEA and A/C RAIN controls.
What to do if Furuno FAR-28 Marine Radar target not tracked correctly?
If a target is not being tracked correctly, adjust the A/C SEA and A/C RAIN controls.
What to do if Furuno FAR-28 Marine Radar range changed but radar picture does not change?
If the range is changed but the radar picture does not change, try hitting the RANGE [+] and [-] keys (or RANGE box) several times. If that does not work, turn the power off and on again to see if the problem might be video freeze up. If the issue persists with a keyboard-type control unit, replacement of the keypad may be required.
What to do if Furuno Marine Radar picture not updated or picture freeze?
If the Furuno Marine Radar picture is not updating or freezes, turn the power off and on again to restore normal operation.
What to do if Furuno FAR-28 Marine Radar range changed but radar picture not changing?
If the range is changed but the radar picture is not changing, try pressing the RANGE [+] and [-] keys several times. If that doesn't work, try turning the radar off and on again. If the issue persists with a keyboard-type control unit, replacement of the keypad may be required. If that does not resolve the issue, the SPU board may need to be replaced.
Why Furuno FAR-28 Marine Radar marks, indications and noise appear but no echo?
If marks, indications, and noise appear but there is no echo, the Tx high voltage protection circuit may have activated. Reset the power to restore normal operation.
Why Furuno FAR-28 Marine Radar data and marks not displayed in Transmit status?
If data and marks are not displayed in Transmit status, replace the SPU board.
Why Furuno FAR-28 Marine Radar incorrect orientation of picture?
If the picture orientation is incorrect:1. The message HDG SIG MISSING appears when the heading pulse is not received during transmitting.2. Replace the gyro interface.
Why Furuno FAR-28 Marine Radar poor discrimination in range?
If there is poor discrimination in range, it may be due to an improper setting of A/C SEA. If A/C SEA is only seen at a very close range, suspect an inaccurate frequency of the reference oscillator.
What to do if Furuno FAR-28 Marine Radar power turned on but radar does not operate at all?
If the power is turned on but the radar does not operate at all:1. Replace the blown fuse.2. Correct the wiring and input voltage.3. Replace the power supply board.
What to do if Furuno FAR-28 Marine Radar antenna not rotating?
If the antenna is not rotating:1. Replace the antenna drive mechanism.2. Press the relay reset button.
