If your Lofrans Measuring Instruments display V=11.6 Vdc, it indicates that the instrument isn’t receiving any signal from the magnetic sensor for more than 5 seconds when UP or DOWN keys are pressed. Here's what you should do: * Check the sensor's electrical connections. * Verify the sensor is operating correctly; if not, replace it. * Examine the sensor and magnet's position and distance on the gypsy. * Check the operation of the electric installation or anchor windlass.
