What to do if Furuno FAR-2107 Marine Radar buttons on trackball module operated but no response?
If the buttons on the trackball module of your Furuno Marine Radar are operated but there is no response, the trackball module may need to be replaced.
What to do if Furuno FAR-2107 range changed but radar picture does not change?
If the range is changed on your Furuno Marine Radar but the picture doesn't update, try pressing the RANGE [+] and [-] keys (or the RANGE box) several times. If this doesn't work and you have a keyboard-type control unit, the keypad may need replacement. If the issue persists, try turning the power off and on again in case of a video freeze.
What to do if Furuno Marine Radar marks, indications and noise appear but no echo?
If your Furuno Marine Radar displays marks, indications, and noise but no echo, the Tx high voltage protection circuit may have activated. Reset the power to restore normal operation.
Why is Furuno FAR-2107 properly tuned but poor sensitivity?
If your Furuno Marine Radar is properly tuned but the sensitivity is poor, possible causes include: 1) A deteriorated magnetron. 2) A detuned MIC. 3) Dirt on the radiator face. 4) Water in the waveguide or feeder line. 5) The second trace echo rejection being ON. To resolve this: 1) Check the magnetron current while transmitting on the 48 nm range; replace if below normal. 2) Check MIC detecting current and tune if below normal. 3) Clean the radiator surface. 4) Remove water from the feeder line. 5) Disable the second-trace echo rejector.
Why is Furuno FAR-2107 tuning adjusted but poor sensitivity?
If you've adjusted the tuning on your Furuno Marine Radar but still have poor sensitivity, the issue might be due to the 2nd trace echo rejector being on, or dirt on the radiator face. Try turning off the 2nd trace echo rejector and cleaning the radiator face.
Why is Furuno FAR-2107 Marine Radar key beep inaudible?
If the key beep is inaudible on your Furuno Marine Radar, the key beep may be turned off. Adjust the key beep level on the OPERATION menu.
What to do if Furuno Marine Radar range rings are not displayed?
If the range rings are not displayed on your Furuno Marine Radar, it could be due to: 1) Adjust the brilliance of range rings on the BRILL menu to see if intensity is increased. 2) SPU board. To resolve this: 1) Replace associated circuit board if unsuccessful. 2) Replace SPU board.
What to do if Furuno FAR-2107 Marine Radar data and marks not displayed in Transmit status?
If data and marks are not displayed in Transmit status on your Furuno Marine Radar, the SPU board may need to be replaced.
What to do if Furuno Marine Radar picture not updated or picture freeze-up?
If the picture on your Furuno Marine Radar is not updating or freezes, the issue could be due to: 1) The bearing signal generator board (in the antenna unit). 2) The SPU board. 3) Video freeze-up. To resolve this: 1) Check the connection of the signal cables. 2) Replace the SPU board. 3) Turn the radar off and on.
What to do if Furuno FAR-2107 is properly tuned but poor sensitivity?
If your Furuno Marine Radar is properly tuned but has poor sensitivity, it could be due to: 1) Deteriorated magnetron 2) Detuned MIC 3) Dirt on radiator face 4) Water ingress to the waveguide or other feeder line 5) Second trace echo rejection is ON To resolve this: 1) Check magnetron current while transmitting on 48 nm range; replace if below normal. 2) Check MIC detecting current; tune MIC if below normal. 3) Clean the radiator surface. 4) Remove water from the feeder line. 5) Disable the second-trace echo rejector.
