Overheat Alarm: The motor will overheat after long time of high
speed running. When the motor temperature is reaching high, it will keep
beeping, and the hoverboard will move very slowly.
If it continues to run, the control system will cut off the power to protect the
motor from damage.
Warning: To prevent overheating, when the motor temperature is too high
and the alarm is beeping, please stop riding the hoverboard, and wait for
the motor cool down before riding.
