5. Care and Maintenance

• Cleaning: Regularly clean your Fitbit Sense and its bands to prevent skin irritation and maintain device functionality. Use a soft, lint-free cloth. For the bands, a mild soap-free cleanser can be used. Ensure the device is completely dry before wearing or charging.
• Water Resistance: The Fitbit Sense is water-resistant up to 50 meters. It can be worn in the shower, pool, or ocean. However, it is recommended to dry the device and bands after getting them wet to prolong their lifespan and prevent skin irritation. Do not use in a hot tub or sauna.
• Charging Contacts: Periodically clean the charging contacts on the back of your watch and on the charging cable with a soft, dry cloth to ensure optimal charging.
• Storage: When not in use for extended periods, store your Fitbit Sense in a cool, dry place away from direct sunlight and extreme temperatures.

6. Troubleshooting

If you encounter issues with your Fitbit Sense, try the following common troubleshooting steps:

• Device Not Responding: If your Sense is unresponsive, try restarting it. Press and hold the inductive button for about 10 seconds until you see the Fitbit logo on the screen.
• Syncing Issues: Ensure Bluetooth is enabled on your smartphone and the Fitbit app is open. Try restarting both your phone and your Sense. If issues persist, unpair and re-pair the device in your phone's Bluetooth settings and the Fitbit app.
• Inaccurate Readings: Ensure your Sense is worn correctly – not too tight or too loose, and positioned about a finger's width above your wrist bone. Clean the sensors on the back of the device.
• Battery Draining Quickly: Frequent use of GPS, continuous heart rate monitoring, and voice assistant features can reduce battery life. Try disabling features you don't need constantly. Ensure background app refresh for Fitbit is optimized on your phone.
• Notifications Not Appearing: Check notification settings in both your phone's system settings and the Fitbit app to ensure they are enabled for the Sense.
