If the Furuno Marine Radar picture isn't updating, consider the following: 1. Check the signal cable connection. 2. Replace the SPU Board. 3. Turn the radar off and on.
How to fix Furuno Marine Radar antenna not rotating?
If the Furuno Marine Radar antenna is not rotating, check these items: 1. Ensure there's no short circuit across #1 and #2 of J461 on the INT-9170 Board. 2. Press the relay reset button. 3. Confirm that the antenna switch is on.
Why is Furuno Marine Radar sensitivity poor after adjusting TUNE control?
If adjusting the TUNE control on your Furuno Marine Radar results in poor sensitivity, consider these potential causes: 1. The magnetron may be deteriorated; with radar transmitting on 48 mm range, check magnetron current and replace the magnetron if the current is below normal. 2. The MIC may be detuned; check MIC detecting current and tune the MIC if it's below normal. 3. There may be dirt on the radiator face; clean the radiator surface. 4. There may be water in the wave-guide or other feeder line; remove the water. 5. Second trace rejection may be ON; disable the second-trace rejector.
How to fix Furuno FAR-2805 CRT brilliance adjusted but no picture?
If the CRT brilliance is adjusted but there is no picture on the Furuno Marine Radar, check these: 1. If it is a single display installation without radar inter-switching, make sure RADAR 1 is selected on the SYSTEM SETTING menu. 2. Check the high voltage supply with utmost care. 3. Replace the SPU Board.
Why Furuno Marine Radar range changed but radar picture does not change?
If the Furuno Marine Radar range is changed but the radar picture does not change, try the following: 1. Hit the [+] and [-] RANGE keys several times; if this doesn't work, the keypad may need replacement. 2. Replace the SPU Board. 3. Replace the Mother Board. 4. Turn the radar off and on.
What causes Furuno FAR-2805 Marine Radar true motion to not work correctly?
If true motion presentation is not working correctly on your Furuno Marine Radar, here are some things to check: 1. Try pressing the MODE key a little harder. 2. Press the MODE key until 'TM' appears. 3. Enter the correct own ship speed. 4. Make sure that speed and compass inputs are accurate.
Why is Furuno Marine Radar picture orientation incorrect?
If the Furuno Marine Radar picture has incorrect orientation, note that the message 'HD SIG MISSING' appears when the heading pulse is not received during stand-by. Replace the gyro interface.
What to do if Furuno FAR-2805 Marine Radar interference rejector is inoperable?
If the interference rejector is inoperable on your Furuno Marine Radar (interference rejection level not displayed), check these: 1. Repair the contact of the key. 2. Replace the SPU Board. 3. Replace the Mother Board.
