I can't stop looking again and again the Safety Control list which mentions
Stop when falling protection.
-Stop when lifted protection
-
Stop when falling protection
-Over-speed warning
-Antiskid vacuum tire
-Disaster recovery design
-Fault alarm and black box
-Power on self test
-Intelligent battery monitoring
As long as it is a safety feature, I guess it doesn't matter if you fall over in the first place, right?
As for the
Disaster recovery design, I have no clue what does it mean.
