Why Furuno FA Marine Radar range rings are not displayed?
If range rings are not displayed on the Furuno Marine Radar, it could be due to the brilliance of range rings being too low. If adjusting the brilliance is unsuccessful, consider replacing the associated circuit board. Alternatively, the SPU board may be faulty, requiring replacement.
Why Furuno FA Marine Radar has poor sensitivity even when tuned?
If the Furuno Marine Radar exhibits poor sensitivity despite proper tuning, the possible causes are: 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. To resolve this, you can: 1. Check magnetron current while transmitting on 48 nm range, and replace the magnetron if the current is below normal. 2. Check MIC detecting current and tune the MIC if it is below the normal value. 3. Clean the radiator surface. 4. Remove water from the feeder line. 5. Disable the second-trace echo rejector.
How to fix Furuno FA when range is changed but picture doesn't?
If the Furuno Marine Radar picture does not change when the range is adjusted, the cause may be a defective range key or video freeze up. Try pressing the RANGE [+] and [-] keys (or RANGE box) several times. If that doesn't work, try turning the power off and on again.
What to do if Furuno FA shows marks but no echo?
If the Furuno Marine Radar displays marks, indications, and noise but no echo, check for a blown fuse in the processor unit.
How to fix Furuno FA Marine Radar picture freeze?
If the Furuno Marine Radar picture is not updating or is frozen, turn the power off and on again to restore normal operation.
Why can't I operate Furuno FA from on-screen boxes?
If you cannot operate the Furuno Marine Radar from the on-screen boxes, the cause is likely the SPU Board. Replace the SPU Board.
Why Furuno FA Marine Radar data and marks are not displayed in transmit status?
If data and marks are not displayed in transmit status on the Furuno Marine Radar, the cause may be the SPU board. Replace the SPU board.
How to enable key beep on Furuno FA?
If the key beep is inaudible on the Furuno Marine Radar (Non-IMO type only), adjust the key beep level on the OPERATION menu.
What causes no noise or echo on Furuno FA Marine Radar when gain is adjusted?
If the Furuno Marine Radar shows marks and indications but no noise or echo when the gain is adjusted with A/C SEA set at minimum, the cause may be the IF amplifier, the signal cable between the antenna and processor unit, or the video amplifier board. To resolve this: 1. Replace the IF amplifier. 2. Check the coaxial cable continuously and its isolation. Disconnect the plug and lugs at both ends of the coaxial cable before checking it with an ohmmeter. 3. Check the video coax line for a secure connection. If the connection is good, replace the SPU board.
What to do if Furuno FA Marine Radar has poor sensitivity after tuning?
If the Furuno Marine Radar has poor sensitivity even after tuning, the cause may be that the 2nd trace echo rejector is on or there is dirt on the radiator face. To solve this: * Turn off the 2nd trace echo rejector. * Clean the radiator face.
