If a user chart isn't showing on your Furuno Marine Radar display, it could be due to several reasons: the user chart may not be selected in monitoring mode, the system might have failed to post-process the chart for radar, or the LAN adapter cable may have loosened. To fix this, ensure that the user chart is selected in monitoring mode. Close the User Chart menu to activate post-processing for the user chart. Also, check and connect the LAN adapter cable.

If the range is changed on your Furuno Marine Radar, but the picture isn't updating, the cause may be a defective range key, SPU board issue, or video freeze-up. Try hitting the RANGE key several times. If this doesn't work, the keypad may need replacement. Alternatively, the SPU board might need replacing. As another option, try turning the radar off and on again.
