Maintenance
To ensure the longevity and optimal performance of your KOSPET Tank T3 Ultra 2, follow these maintenance guidelines:
- Cleaning: Regularly wipe the watch screen and body with a soft, damp cloth. For the strap, use mild soap and water if necessary, then rinse thoroughly and dry completely.
- Water Exposure: While the watch is 5ATM and IP69K water-resistant, avoid prolonged exposure to hot water, steam, or high-pressure water jets, as this can compromise the seals. Always dry the watch completely after swimming or exposure to water.
- Avoid Chemicals: Do not use harsh chemicals, solvents, or abrasive cleaners on the watch or strap, as they can damage the materials.
- Temperature Extremes: Although designed for extreme temperatures, avoid leaving the watch in direct sunlight for extended periods or in extremely cold environments when not in use.
Troubleshooting
If you encounter any issues with your KOSPET Tank T3 Ultra 2, refer to the following common solutions:
- Watch not turning on: Ensure the watch is fully charged. Connect it to the charger for at least 30 minutes.
- Cannot pair with phone: Make sure Bluetooth is enabled on your phone and the watch is within range. Restart both the watch and your phone, then try pairing again through the 'KOSPET FIT' app.
- Inaccurate health data: Ensure the watch is worn snugly on your wrist, not too tight or too loose. Clean the sensor on the back of the watch.
- Notifications not received: Check your phone's notification settings for the 'KOSPET FIT' app and ensure all necessary permissions are granted. Also, verify that notifications are enabled within the app for specific applications.
- GPS not connecting: Ensure you are in an open outdoor area with a clear view of the sky. Allow a few minutes for the watch to acquire satellite signals.
