To Next PageTo Next PageWhy does my Sea Tel ST94-21 Antenna show a Gyro Compass failed error code 0001?
A 'Gyro Compass has failed' error code 0001 indicates that either no Gyro Compass is available, or the Gyro Compass input is noisy, occasionally inaccurate, or occasionally unavailable. When no Gyro Compass is available, ensure that Satellite Reference Mode is turned ON.
