What's wrong with the new Combax digital perpetual calendar?

The digital perpetual calendar in Kangbas can't be opened, indicating that the digital perpetual calendar is in a dead state. The solution is to open the shell of the digital calendar, find the 470uF/ 10V capacitor inside, and connect its two pins in series with metal. At this point, the digital perpetual calendar will be restored to the factory settings.

If this method still can't solve the problem, it's better to return it to the original manufacturer.
