4. Maintenance
4.1 Cleaning
To maintain the appearance and functionality of your smartwatch:
- Wipe the watch face and strap regularly with a soft, damp cloth.
- Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the materials.
- Ensure the watch is dry before wearing it, especially after cleaning or exposure to water.
4.2 Water Resistance (IP68)
The NO.1 F3 Smartwatch is rated IP68, meaning it is dust-tight and protected against continuous immersion in water up to a specified depth (typically 1.5 meters for 30 minutes). This makes it suitable for activities like swimming and showering.
Important Considerations:
- Do not press any buttons while the watch is submerged in water.
- Avoid exposure to hot water, steam, or high-pressure water jets, as this can compromise the water resistance seals.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
- Water resistance is not a permanent condition and may decrease over time with normal wear and tear.
4.3 Battery Care
The smartwatch uses a button cell battery designed for long life. To maximize battery longevity:
- Avoid extreme temperatures, which can degrade battery performance.
- If the battery is replaceable, ensure it is replaced by a qualified technician or follow specific instructions provided with the replacement battery.

5. Troubleshooting
If you encounter issues with your NO.1 F3 Smartwatch, refer to the following common solutions:

- Inaccurate Pedometer/Sleep Data:
- Ensure the smartwatch is worn correctly and securely on your wrist.
- Calibrate the device through the companion app if such an option is available.
