The notification scrolls for 10 seconds or until the call is answered. You can dismiss the notification at any time by pressing the button on your tracker. Visit https://www.fitbit.com/devices

What is my Charge HR made of?

While all stainless steel contains nickel and may cause an allergic reaction in someone with nickel sensitivity, the amount of nickel in all Fitbit products meets the European Union's stringent Nickel Directive.
