3.2 Sizing and Wearing

Accurate sizing is crucial for optimal performance and comfort. Please follow these steps to determine your correct ring size:

1. Step 1: Take a long non-elastic rope or paper, and wrap it around your finger.
2. Step 2: Make the rope or paper fit closely to your fingers to avoid being too loose or too tight, which may cause size deviation.
3. Step 3: Mark the junction part on the rope or paper.
4. Step 4: Lay the rope or paper flat, and measure the length. It is recommended to measure multiple times for more accurate data.

Refer to the size chart below to match your measurement to the appropriate ring size. The dimensions have a measurement tolerance of ±0.2mm.

For best performance and accuracy, we recommend wearing the COLMI R02 Smart Ring on your index finger. The middle and ring fingers are also suitable. Ensure the sensor on the inside of the ring is in contact with your skin for accurate heart rate and blood oxygen measurements.

5. Maintenance

5.1 Cleaning

The COLMI R02 Smart Ring is IP68 waterproof, allowing you to swim, wash hands, and shower while wearing it.

Wipe the contact area dry promptly if it comes into contact with water.
