3. Setup
- Connect the Sensor Ring: Locate the USB port on your compatible Wellue/Viatom sleep monitor (e.g., SleepU, Visualoxy, CheckmeO2 Max). Insert the USB connector of the Sensor Ring firmly into this port. Ensure a secure connection.
- Position the Sensor Ring: Gently slide the silicone ring onto your finger. It is recommended to use your index finger or thumb for optimal readings. Ensure the sensor sits comfortably and securely, but not too tightly, to avoid restricting blood flow. The sensor should be positioned so that the light emitter and detector are aligned on opposite sides of your finger.
- Power On the Main Device: Refer to the instruction manual of your specific Wellue/Viatom sleep monitor for details on powering it on and initiating a recording session.

4. Operating Instructions
Once the Sensor Ring is properly connected and positioned, and your main monitoring device is active, it will begin collecting data. The Sensor Ring acts as the probe, transmitting SpO2 and heart rate data to the main unit.
- Data Collection: The Sensor Ring continuously measures your blood oxygen levels and heart rate.
- Viewing Data: Data collected by the Sensor Ring is processed and displayed by your compatible Wellue/Viatom sleep monitor and its associated smartphone application. Refer to your main device's manual for instructions on viewing real-time data and accessing historical reports.
- Recording Sessions: Ensure your main device is set to record for the desired duration, typically throughout your sleep period.

5. Maintenance
- Cleaning: To clean the Sensor Ring, gently wipe the silicone surface with a soft, damp cloth. Do not use harsh chemicals, abrasive cleaners, or immerse the sensor in water. Ensure the USB connector remains dry.
- Storage: Store the Sensor Ring in a clean, dry place away from direct sunlight and extreme temperatures. Avoid bending or kinking the cable excessively.
- Inspection: Regularly inspect the Sensor Ring and its cable for any signs of wear, damage, or fraying. If any damage is observed, discontinue use and replace the sensor.
6. Troubleshooting
If you encounter issues with your Wellue Sensor Ring, please refer to the following common troubleshooting steps:
- No Reading or Intermittent Data:

- Verify the Sensor Ring is correctly positioned on your finger, with the sensor elements aligned.
- Check that your finger is clean and dry.
- Avoid excessive movement during monitoring.
- Confirm the main monitoring device is powered on and functioning correctly.
- Inaccurate Readings:
- Ensure the sensor is not too tight, which can restrict blood flow and affect accuracy.
- Avoid using the sensor on fingers with nail polish or artificial nails, as this can interfere with readings.
- Verify the sensor is clean and free from dirt or debris.
- "ERROR 4" or Similar Error Messages:
- This error typically indicates a sensor malfunction. Try disconnecting and reconnecting the sensor.
