What if the device cannot be turned on?
What to do if the device unexpectedly shuts down?
What should I do when the machine is in standby mode and beeps every 5 seconds, resonates 5 times continuously for 25 seconds, and cycles once per hour?
What is the reason for the device to automatically release its charging state after being fully charged?
What should I do if the standby status indicator light is not on?
