Doorbell Pro First Connection problems

Hi. Today I’ve got my Doorbell Pro. At my first try to connect the bell with the App, the network doesn’t connected to the bell. My smartphone can’t connected to the Ring WLAN. at the second try, the bell doesn’t go in the Setup status. The light of the bell is still blue in the top and flash. I’ve read, the bell must connected with the wires for 1h to load the battery(?!) Now it’s more than 6h. And nothing. Still just the flashing light in the top of the ring. What’s wrong?! Is the battery broken?
