Introduction

Hello Everyone,I'm new to your community and would like to say thanks for letting me join!! I apologize if my first question seems extremely elementary, but as I said I'm new. I've installed my Ring Video Doorbell 2(battery operated) and would like to know if the circular blue light is supposed to stay on all of the time or just when someone pushes it? One other question I have is how badly does the cold weather affect the doorbell? I live on the East Coast and we've been having some extremely cold temperatures lately, -5°F, and would like to ask if anyone has any advice about what I can do to keep the cold from damaging the doorbell? Thank you
