Does this problems appears after a car or train transportation?
NOTE: macro x and high x have an automatic “sensor searching feature” which starts searching once the macro is on the holder and gets a vibration. This means that during transportation in car or train with the head unit on the holder, macro x & high x will constantly search for sensors, which he usually does not find as the bike is not moving.
The problem is that the searching process is consuming a lot of energy. It means that the battery is suffering a lot if the head unit is staying for a long time in the searching cycle, which may lead to a freezing of the head unit once the critical voltage of 2.7 volts is reached.
