Why is Furuno FAR-2218 Marine Radar picture is not updated with each sweep?
If the picture on your Furuno Marine Radar is not updated with each sweep, the issue may be with the motor/gears. Check the motor and gears and replace them if worn.
What to do if range changed but radar picture does not change on Furuno FAR-2218?
If the range is changed but the radar picture does not change on your Furuno Marine Radar, it could be due to a defective range key or a video freeze-up. Try adjusting the range with the control unit or the [RANGE] box several times. If that does not work, try turning the power off and on again to see if the problem might be video freeze up. If still unsuccessful, the keypad may need replacement.
Why is my Furuno FAR-2218 Marine Radar properly tuned but has poor sensitivity?
If your Furuno Marine Radar is properly tuned but has poor sensitivity, possible causes include a deteriorated magnetron, a detuned MIC, dirt on the radiator face, water ingress to the waveguide or other feeder line, or the second trace echo rejection being active. Consider the following: 1. Check magnetron current with the radar transmitting on 48 nm range. If the current is below normal, the magnetron may be defective and need replacement. 2. Check the MIC detecting current. If it is below the normal value, the MIC may have become detuned and needs tuning. 3. Clean the radiator surface. 4. Remove water from the feeder line. 5. Disable the second-trace echo rejector.
How to display range rings on Furuno FAR-2218 Marine Radar?
If range rings are not displayed on your Furuno Marine Radar, it may be because they are turned off. Try turning on the range rings with [RANGE RING] in the [NAVTOOL] menu. If they still do not appear, their brilliance may be too low; adjust their brilliance in the [BRILL] menu.
What causes marks, indications, and noise but no echo on Furuno FAR-2218?
If you are seeing marks, indications, and noise but no echo on your Furuno Marine Radar, the Tx high voltage protection circuit may have activated. Reset the power to restore normal operation.
Why is the tracked target not tracked correctly on Furuno FAR-2218 Marine Radar?
If a target is not being tracked correctly on your Furuno Marine Radar, it may be due to poor definition of targets in sea clutter. Adjust A/C SEA and A/C RAIN.
What causes poor discrimination in range on Furuno Marine Radar?
If you are experiencing poor discrimination in range on your Furuno Marine Radar, it could be due to the sea clutter control not functioning properly. This may be caused by improper setting of A/C SEA. If A/C SEA is seen only at very close range, suspect inaccurate frequency of reference oscillator.
Why are data and marks not displayed in transmit status on my Furuno FAR-2218?
If data and marks are not displayed in transmit status on your Furuno Marine Radar, the issue may be with the MAIN board inside the Processor unit. Consider replacing the MAIN board.
What to do if Furuno FAR-2218 power is on but nothing appears on the monitor?
If the power is on but nothing appears on the monitor of your Furuno Marine Radar, the brilliance might be too low. Adjust the brilliance.
Why does my Furuno Marine Radar show marks, indications, and noise but no echo?
If your Furuno Marine Radar shows marks, indications, and noise but no echo (and the transmission leak representing your own ship position is absent), possible causes include activation of the TX high voltage protection circuit, a faulty magnetron, or issues with the MD or SPU boards inside the antenna. To troubleshoot: 1. Reset the power to restore normal operation. 2. Check the magnetron current and replace the magnetron if necessary. 3. Replace the MD board. 4. Replace the SPU board.
