7. Sizing Guide

To ensure accurate data collection and comfortable wear, it is important to select the correct ring size. We recommend wearing the ring on your index finger to avoid accidental touches.

7.1 Measure Finger Method

1. Step 1: When measuring, choose a thin, non-stretchy wire or string. Wrap it around your finger and mark the point where it overlaps with a pen or other tool. Ensure the wire is tightened appropriately, but not too loose.
2. Step 2: Straighten the marked wire and measure its length with a ruler. Compare this measurement to the 'Perimeter' column in the size chart below to find your corresponding ring size.

• Cleaning: Wipe the ring and charging case with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: To prolong battery life, avoid fully discharging the ring frequently. Charge it regularly, even if not in constant use.

9. Troubleshooting

If you encounter issues with your CNBRO Smart Ring, please refer to the following common solutions:

• Ring Not Turning On: Ensure the ring is fully charged. Place it in the charging case and verify the charging indicator.
• Charging Case Not Working: Check the charging cable and power source. If the case itself is not charging the ring, ensure the ring is correctly seated. If issues persist, the charging case may require replacement.

  1. Ensure Bluetooth is enabled on your phone.
  2. Make sure the Jring app is updated to the latest version.
  3. Restart both your phone and the smart ring (by placing it in the charging case and taking it out).
  4. Try unpairing and re-pairing the device through the app's settings.
• Inaccurate Data Readings: Ensure the ring is worn correctly and snugly on your finger. Clean the sensors on the inside of the ring.
