How to display 6 index lines on Furuno Marine Radar?
If the Furuno Marine Radar is only displaying 2 parallel index lines when 6 are desired, the cause may be an incorrect setting of index line intervals. Adjust the index line interval. Also, the setting for the number of index lines to display may be inappropriate; check the menu setting for the number of index lines.
Why Furuno FA range is changed but picture is not?
If the Furuno Marine Radar range is changed but the picture does not change, the cause may be a defective range key, the SPU board, or video freeze-up. To resolve this: 1. Try pressing the RANGE [+] and [-] keys several times. If unsuccessful, replacement of the keypad may be required. 2. Replace the SPU board. 3. Turn the radar off and on.
What to do if Furuno Marine Radar shows marks but no echo and transmission leak?
If the Furuno Marine Radar displays marks, indications, and noise but no echo (and the transmission leak representing own ship position is absent), the possible causes are: a TX fuse, the magnetron, the modulator board, or the SPU board. You can try the following: 1. If the fuse is blown, replace it. If it blows again, the modulator or associated circuit may be defective. 2. Check the magnetron current and replace the magnetron if necessary. 3. Replace the modulator board. 4. Replace the SPU board.
What to do if Furuno Marine Radar does not turn on?
If the Furuno Marine Radar does not operate after being powered on, the possible causes are: a blown fuse, incorrect mains voltage/polarity, or a faulty power supply board. You can try the following: replace the blown fuse, correct the wiring and input voltage, or replace the power supply board.
Why Furuno Marine Radar antenna is not rotating?
If the Furuno Marine Radar antenna is not rotating, the cause may be the antenna drive mechanism or a defective antenna drive motor relay. To resolve this, you can replace the antenna drive mechanism or press the relay reset button.
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.
Why is Furuno Marine Radar picture orientation incorrect?
If the picture orientation is incorrect on the Furuno Marine Radar, it may be due to the SPU board or the gyro interface. The message HDG SIG MISSING appears when the heading pulse is not received during standby. Replacing the gyro interface may solve the issue.
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.
What causes Furuno Marine Radar ARPA target not to be tracked correctly?
If an ARPA target is not being tracked correctly on the Furuno Marine Radar, it may be due to poor definition of targets in sea clutter. Adjust the A/C SEA and A/C RAIN.
How to display range rings on Furuno FA?
If range rings are not displayed on the Furuno Marine Radar, try turning on the range rings in the MARK menu. If they still do not appear, their brilliance may be too low; adjust their brilliance in the BRILL menu.
