4. Maintenance
4.1 Cleaning the Bands
To ensure hygiene and prolong the life of your silicone replacement bands:
- Wipe the bands regularly with a soft, damp cloth.
- For deeper cleaning, use a mild soap solution and rinse thoroughly with clean water.
- Ensure the bands are completely dry before reattaching them to the tracker or wearing.
- Avoid using harsh chemicals or abrasive materials, as these can damage the silicone.
4.2 Water Resistance
The Y99/G Fitness Tracker is rated IP68 waterproof, meaning it is protected against continuous immersion in water up to a certain depth and duration. This makes it suitable for activities like swimming.
- You can wear the tracker while swimming or showering.
- Avoid exposing the tracker to hot water, steam, or high-pressure water jets, as this may compromise the seal.
- After exposure to chlorinated or saltwater, rinse the tracker with fresh water and dry it thoroughly.

5. Troubleshooting
If you encounter issues with your Y99/G Replacement Bands or Fitness Tracker, refer to the following common solutions:
- Band not attaching securely: Ensure the quick-release pins (if applicable) are fully retracted and aligned with the holes on the tracker module. Apply gentle pressure until you hear or feel a click.
- Tracker not charging: Verify that the metal contacts on the tracker are clean and making full contact with the USB port. Try a different USB port or power adapter. Ensure the tracker is inserted correctly into the USB port.
- Tracker not responding: Ensure the tracker is sufficiently charged. If it's unresponsive, try restarting it (refer to your original Y99/G Fitness Tracker manual for specific restart instructions).
- Inaccurate readings: Ensure the tracker is worn snugly on your wrist, about one finger's width above your wrist bone. Clean the sensor on the back of the tracker regularly.
