3. Maintenance

3.1 Cleaning Your Watch

Regularly clean your watch and bands to prevent buildup and maintain hygiene. Use a soft, damp cloth to wipe the watch body and screen. For silicone bands, mild soap and water can be used. Ensure the watch is completely dry before charging or prolonged use.

3.2 Charging Best Practices

  • Use only the provided COROS charging cable.
  • Avoid exposing the charging port to moisture.
  • Charge the watch in a cool, dry environment.
  • Do not leave the watch charging for extended periods after it is fully charged.

3.3 Software Updates

Periodically check for software updates via the COROS app. Updates often include performance improvements, new features, and bug fixes. Ensure your watch is sufficiently charged before initiating an update.

4. Troubleshooting

4.1 Common Issues

  • Watch not turning on: Ensure the watch is fully charged. Connect it to the charger for at least 30 minutes.
  • GPS signal issues: Ensure you are in an open area with a clear view of the sky. Sync your watch with the COROS app regularly to update GPS satellite data.
  • Heart rate inaccuracy: Ensure the watch is worn snugly on your wrist, one finger-width above the wrist bone. Clean the optical sensor regularly.
  • Pairing problems: Ensure Bluetooth is enabled on your phone and the watch. Try restarting both devices and the COROS app.
