3. Maintenance
3.1 Water Resistance
The R13 Smart Ring boasts a 5ATM waterproof rating, equivalent to IP68. This means it is designed to withstand water exposure from activities such as washing hands, showering, swimming, or even diving. There is no need to worry about moisture affecting its functionality during these common scenarios. However, it is not recommended for use in hot water environments like saunas or hot springs, as extreme temperatures can compromise the seals.

3.2 Cleaning
To maintain the ring's appearance and ensure accurate sensor readings, regularly clean it with a soft, slightly damp cloth. Gently wipe the exterior and especially the sensor area on the inside of the ring. Avoid using harsh chemicals, abrasive cleaners, or sharp objects, as these can damage the finish or sensors.
3.3 Storage
When not in use for extended periods, store the R13 Smart Ring in its wireless charging case. Keep the case and ring in a cool, dry place away from direct sunlight and extreme temperatures. It is advisable to ensure the ring has some charge before long-term storage to prevent deep discharge, which can affect battery life.
4. Troubleshooting
If you encounter any issues with your Ola Esporte R13 Smart Ring, please refer to the following troubleshooting tips:
- Ring Not Charging:
- Ensure the ring is correctly seated in the wireless charging case.
- Check that the magnetic charging cable is securely connected to the case and a functional power source (1A or less).
- Try using a different charging cable or power adapter to rule out faulty accessories.
- Unable to Pair with App:
- Verify that Bluetooth is enabled on your smartphone and the ring is sufficiently charged.
- Restart both the Smart Ring (by placing it in the charging case and then removing it) and your smartphone.
- In your phone's Bluetooth settings, forget the device and then attempt to re-pair it through the 'ECTRI' app.
- Inaccurate Health Data:
- Ensure the ring is worn snugly on your finger, but not uncomfortably tight. A loose fit can affect sensor accuracy.
- Clean the sensors on the inside of the ring to remove any dirt, sweat, or lotion buildup.
- Make sure the 'ECTRI' app is updated to the latest version.
- Display Not Responding:
- Check the battery level of the ring. If it's low, place it in the charging case.
- If the ring is fully charged and the display is still unresponsive, try restarting the ring by placing it in the charging case for a few seconds and then removing it.
If these steps do not resolve the issue, please contact customer support.
