If this issue occurs that means the sensor firmware is in a loop and cannot proceed with the proper commands.
- The fix for this is to unplug the stand.
- Then you must wait till the sensor is completely without power.
- This takes between 36 to 48 hours.
- After this time the sensor should have all power removed.
- Then you can plug in the stand and have the sensor powered back on.
- At this time the sensor should come back online and allow it to be unlocked.
