1. If the frozen issue is intermittent, please update to the latest MagArrow embedded software and survey manager, which can be found in the download section of MagArrow. The compass status can now be monitored on the browser interface. If the compass fails, power cycle the MagArrow.
2. The frozen issue often occurs during the startup when the MagArrow faces exactly north/south/west/east. The compass initialization sometimes fails when one of the compass readings is close to 0. The latest embedded software greatly improves the robustness of the startup procedure. However, if the frozen issue persists, please power up your MagArrow facing north-west.
3. If the above two steps do NOT fix the issue, the MagArrow has to come back for repair.
