Matters needing attention in the use of learning machine

1. Don't switch frequently: switch repeatedly like this. Although it looks normal, it is not conducive to the life of the learning machine. After all, learning machines are alive. Frequent switching will lead to fast battery loss and eventually shorten battery life.

2, often remove the stains on the button: stains are easy to invade the button, there is no problem in a short time, but after a long time, there are more stains, and the button will be invalid.

3, the protection of the learning machine interface: not only the USB interface, but also the headphone interface needs protection. Otherwise, the learning machine looks good, but in the end it can't be connected to the computer and can't be updated.
