The tablet supports connection to computers, Android devices, and Chromebooks. If you encounter the situation of "drawing a vertical line horizontally" or "drawing a circle to become an ellipse" during use, it means that the current user mode is incorrect, please make the following adjustments.
1. Computer mode -- the factory default is the computer use mode, no need to adjust.
2. Mobile phone or tablet mode--need to adjust the [mode switch] on the left side of the tablet to the [green] position.
3. Chromebook mode -- the [mode switch] on the left side of the tablet needs to be adjusted to the [black] position.
Note: The consistency of the line drawing direction can only be ensured by adjusting in the above way.
