Setup Guide
Charging Your Device
Before initial use, fully charge your Inspire 3. Connect the charging cable to a USB power source and align the magnetic pins with the charging port on the back of your tracker. A full charge typically takes about 1-2 hours.
Initial Pairing and App Installation
To set up your Inspire 3, you will need the Fitbit app. Download the Fitbit app from the Apple App Store (for iPhone) or Google Play Store (for Android devices). Once installed, open the app and follow the on-screen instructions to create a Fitbit account or log in to an existing one. The app will guide you through the process of pairing your Inspire 3 via Bluetooth.
Wearing Your Inspire 3
For accurate tracking, wear your Inspire 3 comfortably on your wrist. For general wear and sleep tracking, the device should be worn loosely enough to move up and down your wrist. For exercise, tighten the band slightly to ensure the heart rate sensor maintains contact with your skin.
