On first use, the Dash will prompt you with an initial setup wizard to get you started riding with the Dash. Select your language and the Dash will walk you through the basic operation of the Dash buttons.
The Dash setup wizard will also walk you through pairing to your phone through the Stages Cycling app. If you do not have the Stages Cycling app, you can still enter all of this information through the setup wizard.
Once the initial setup is complete, you can start using your Dash with your Automatic profile or make a new profile and start customizing your Dash ride pages.
