  1. Create Or Sign In To Your Vizio SmartCast account 

Now launch the SmartCast app on your smartphone. You’ll be asked to either sign in as a guest or create a new account. If you only want to update your Soundbar’s firmware and read the manual, you can sign in as a guest. But if you intend to use the app to control your Soundbar, I’d suggest creating an account and signing in.
