¶ FAQ
Q: The settings do not take effect after following the above tutorial correctly. How to resolve this?
A: First, check if the hardware RTC battery has power. Insert it into the RTC slot to charge it for an extended period, then try again. Alternatively, replace the RTC battery. If the issue persists after multiple attempts, there may be a problem with the circuit, and the device needs to be sent back to the manufacturer for repair.
