Operating Instructions
1. Basic Navigation
The Vigor 2 L tracker operates using a single touch-sensitive button located below the screen. Short presses cycle through different display screens (e.g., time, steps, heart rate). A long press may activate specific functions or enter sub-menus, depending on the current screen.
2. Activity Tracking
The tracker automatically records daily activity metrics including steps taken, distance covered, calories burned, and active minutes. This data is synchronized with the app for detailed viewing and progress tracking.

Maintenance

Regularly clean the tracker and strap to maintain hygiene and prevent skin irritation. Use a soft, damp cloth to wipe the device. For the silicone strap, mild soap and water can be used. Ensure the device is completely dry before wearing or charging.

To prolong battery life, avoid fully discharging the tracker frequently. Charge the device when the battery indicator is low. Use only the provided charging cable. Store the device in a cool, dry place when not in use for extended periods.
Troubleshooting
1. Device Not Charging
- Ensure the charging cable is securely connected to both the tracker and the USB power source.

2. Syncing Issues with App
- Verify that Bluetooth is enabled on your smartphone.
- Ensure the tracker is within Bluetooth range of your smartphone.
- Restart both the tracker and your smartphone.
- If issues persist, unpair the device from the app and your phone's Bluetooth settings, then attempt to re-pair.
3. Incorrect Time Display
- The tracker's time is synchronized with your smartphone. Ensure the tracker is successfully paired and synced with the app.
- If the tracker completely powers down, it may require re-syncing with the app to correct the time.
4. Excessive Vibrations
- Check the notification settings within the BIGGERFIVE app. Adjust or disable unwanted alerts (e.g., sedentary reminders, activity recognition notifications).
- Ensure 'Do Not Disturb' mode is configured correctly if you wish to silence vibrations during specific times.
5. Strap Durability Concerns
- While the liquid silicone strap is designed for comfort and durability, proper handling is essential. Avoid excessive pulling or twisting.
