What to do if Furuno FAR-2107 Marine Radar power is on but nothing appears on monitor?
If the Furuno Marine Radar is powered on but the screen is blank, the brilliance may be set too low. For keyboard-type control units, rotate the BRILL control clockwise. If you have a trackball-type control unit, press any of the F1-F4 keys for five seconds to increase the brilliance to "50".
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.
What to do if Furuno Marine Radar marks, indications and noise appear but no echo (Transmission leak representing own ship position is absent)?
If your Furuno Marine Radar shows marks, indications, and noise without an echo (and the transmission leak representing your ship's position is absent), the possible causes are: 1) The TX high voltage protection circuit has activated. 2) Magnetron failure. 3) Modulator board issue. 4) SPU board problem. To resolve this: 1) Reset the power. 2) Check and replace the magnetron if necessary. 3) Replace the modulator board. 4) Replace the SPU board.
What to do if Furuno FAR-2107 true motion presentation not working correctly?
If the true motion presentation on your Furuno Marine Radar isn't working correctly, here are some things to check: 1) If you have a full keyboard, ensure the MODE key makes good contact by pressing it firmly. 2) Make sure the TM display is selected by pressing the MODE key or operating the PRESENTATION MODE box until TM appears. 3) Verify that your own ship speed is entered correctly. 4) Ensure that both speed and compass inputs are accurate.
What to do if Furuno FAR-2107 Marine Radar range changed but radar picture not changing?
If you change the range on your Furuno Marine Radar but the picture does not update, the cause may be: 1) A defective range key. 2) An issue with the SPU board. 3) Video freeze up. To solve this: 1) Try pressing the RANGE [+] and [-] keys several times; if this doesn't work, the keypad may need to be replaced. 2) Replace the SPU board. 3) Turn the radar off and on again.
What to do if Furuno FAR-2107 Marine Radar picture is not updated with each sweep?
If the picture on your Furuno Marine Radar isn't updating with each sweep, it could be due to: 1) Slots in the rotating disc in the antenna unit. 2) The motor brushes. To fix this: 1) Remove any foreign material (like carbon or grease) from the slots. 2) Replace the motor brushes if they are shorter than 6 - 7 mm.
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.
