What to do if range changed but radar picture does not change on Furuno FAR-2228-BB Marine Radar?

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.
