Your SkyBell HD is designed to be self-diagnostic and will blink certain patterns of LEDs to let you know the state. Once the SkyBell is installed, the doorbell button should turn a green to indicate a successful connection with your WiFi Router.
Once you successfully sync, you typically will not need to re-sync your SkyBell. If you ever need to re-sync your SkyBell follow these instructions.
