Charging Guidelines
- Use only the provided charging cable.
- Avoid charging in extreme temperatures.
- Do not leave the watch on charge for extended periods after it is fully charged.
Maintenance and Care
Cleaning
Wipe the watch and strap regularly with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the finish or sensors.
Water Resistance Guidelines
While the watch is water-resistant up to 5 ATM, avoid prolonged exposure to hot water, steam, or high-velocity water jets, as these can compromise the seals. Rinse the watch with fresh water after exposure to saltwater or chlorinated water.
Storage
Store the smartwatch in a cool, dry place when not in use. Avoid direct sunlight or extreme temperatures.
Troubleshooting
- Watch not turning on: Ensure the watch is fully charged.
- Cannot pair with smartphone: Make sure Bluetooth is enabled on your phone, the app is open, and the watch is within range. Restart both devices if necessary.
- Inaccurate sensor readings: Ensure the watch is worn snugly on your wrist, not too tight or too loose. Clean the sensor area on the back of the watch. Avoid speaking or moving excessively during measurements.
- Short battery life: Check if GPS or continuous health monitoring features are constantly active. Adjust settings in the app to optimize battery usage.
- Weak signal for heart rate: Hold still, avoid speaking or moving, and ensure your finger is moist if using a finger-based measurement method (if applicable).
