> You can turn the dials to set the correct Weight and Height then press the "UPDATE" button below.
>Please ensure that your bluetooth is on.
> When you press UPDATE you should have your Stryd nearby.
> A window will pop up reading "Connecting to Stryd" and "Please Activate Your Stryd"

> The same window will read "Synchronizing Profile Information" and the light on your Stryd should flash.
