The indicator light on the keyboard can indicate the working status of the keyboard. By using these instruction functions, you can also quickly debug.

The following prerequisites for troubleshooting are that at least the keyboard can recognize when the USB is plugged in, and the keys can trigger.

All references in the text to pressing LShift+RShift+XX refer to holding down the left Shift and right Shift first and press XX key once. You can then release the left and right shifts. Only press one command at a time. To press another command, you need to release the left and right Shift keys, and then press the left and right Shift keys again.

Important point: The result of outputing battery level in text is very useful for troubleshooting.
