Why is Furuno FAR-28x7 Marine Radar tuning adjusted but poor sensitivity?
If you've adjusted the tuning on your Furuno Marine Radar but are experiencing poor sensitivity, it could be due to: * The 2nd trace echo rejector being on. Turn off the 2nd trace echo rejector. * Dirt on the radiator face. Clean the radiator face.
What to do if adjust GAIN with A/C SEA set at minimum. Marks and indications appear but no noise or echo on Furuno FAR-28x7 Marine Radar?
If, with the GAIN adjusted and A/C SEA set to minimum, marks and indications appear but there is no noise or echo, check the following: 1. IF amplifier: Replace the IF amplifier. 2. Signal cable between antenna and processor unit: Check the continuity and isolation of the coaxial cable, disconnecting the plug and lugs at both ends before using an ohmmeter. 3. Video amplifier board: Check the video coax line for a secure connection. If the connection is good, replace the SPU board.
Why Furuno FAR-28x7 brilliance adjusted but no picture?
If you've adjusted the brilliance but there's still no picture on your Furuno Marine Radar, the SPU board may need to be replaced.
What to do if Furuno FAR-28x7 range rings are not displayed?
If the range rings are not displayed on your Furuno Marine Radar, try turning them on using the 0 RINGS option in the MARK menu. If they still don't appear, their brilliance may be too low; adjust their brilliance in the BRILL menu.
Why are 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 one of the following reasons: 1. Try to adjust the brilliance of range rings on the BRILL menu to see if intensity is increased. Replace associated circuit board if unsuccessful. 2. SPU board. Replace SPU board.
How to fix incorrect orientation of picture on Furuno Marine Radar?
