Switching the fitness ring is not working properly.

What you want to ask is what if the switch fitness circle doesn't run? Treadmill failure, sensor failure.

1. Treadmill failure: Running will lead to the failure of fitness activities, so it is necessary to check whether the treadmill works normally.

2. Sensor failure: When the sensor is abnormal, it will lead to abnormal operation of the fitness circle, so it is necessary to check whether the sensor works normally.
