Why can't some math problems be recognized by BBK s6 home education machine?
Why can't the little cloth wisdom on step-by-step tutoring machine S6 be swept out?

1. Check whether the light of the scanning pen is turned on.

2. Can't sweep the topic? What are the tips?

3. Whether the power of the machine is enough.

4. Enter System Settings-Applications-All-Smart Question and Answer-Clear Data, and then restart the tutor to scan again. I hope I can help you!
