- H10 Sensor and Strap: Detach the sensor from the strap after each use. Rinse the strap under running water and hang it to dry. Wash the strap regularly (e.g., weekly) in a washing machine at 40°C (104°F) in a laundry bag. Do not use bleach or fabric softener.
5.2. Battery Care
- Charge your Vantage V3 regularly, but avoid letting the battery completely drain frequently.
- For long-term storage, charge the watch to about 50% and store it in a cool, dry place.
- The H10 sensor uses a user-replaceable CR2025 coin cell battery. Replace it when the Polar Flow app indicates low battery.
5.3. Storage
- Store both devices in a dry, dust-free environment away from extreme temperatures.
6. Troubleshooting
- Watch not turning on or charging: Ensure the charging cable is securely connected to both the watch and a working USB power source. Clean the charging contacts on the watch. Try a different USB port or charger.
- GPS not connecting: Ensure you are in an open outdoor area with a clear view of the sky. Wait a few minutes for the watch to acquire a GPS signal. Sync your watch with Polar Flow to update GPS satellite data.
- Heart rate not accurate or connecting (H10): Ensure the electrodes on the strap are sufficiently moistened. Adjust the strap for a snug fit. Check that the H10 sensor is correctly paired with your watch or app. Replace the H10 battery if necessary.
- Data synchronization issues: Ensure Bluetooth is enabled on your smartphone and the Polar Flow app is open. Restart both your watch and smartphone. Try unpairing and re-pairing the devices.
