Reset ProV1 to Factory Settings
Note: You can reset the ProV1 to Factory Settings at any
time (e.g. When connecting to new WiFi Network). The reset
button is located on the back of the device. Make sure that
the device is not in Sleep-Mode when resetting the device.
You may have to press the doorbell button once before
resetting the device.
Carefully press the 'Reset' button for
approx. 5-8 seconds. After the video
doorbell has been successfully reset to
the factory settings, a short ring will sound.
The status-LED flashes red after the reset
is complete.
