Maintenance
Cleaning Your Ring
To maintain hygiene and optimal sensor performance, clean your OURA Ring 4 regularly. You can wash it with mild soap and water when you wash your hands. For a more thorough cleaning, remove the ring and gently wipe it down with a soft cloth. Ensure the ring is dry before placing it back on the charger or your finger.
Water Resistance
The OURA Ring 4 is water-resistant up to 100 meters. This means it is safe for use during swimming, showering, and other water-based activities. However, prolonged exposure to harsh chemicals or extreme temperatures should be avoided to preserve the ring's integrity.
Troubleshooting
Connectivity Issues
If your OURA Ring 4 is not connecting to the app, ensure Bluetooth is enabled on your smartphone and the ring is within range. Try restarting both your phone and the Oura App. If the issue persists, unpair and re-pair the ring through the app settings.
Battery Life Concerns
If you experience significantly reduced battery life (less than the advertised 8 days), ensure the ring is charging correctly and that the charging contacts are clean. Frequent use of certain features or continuous data syncing can impact battery duration. If the problem continues, contact OURA support.
Inaccurate Sensor Readings
Ensure your OURA Ring 4 fits snugly on your finger. A loose fit can lead to inaccurate data. Also, ensure the sensors on the inside of the ring are clean and free from debris. If readings remain inconsistent, a soft reset of the ring (via the app) may help.
