COLMI R07 Smart Watch for Men and Women with Charging Case, Heart Rate and Blood Oxygen Monitor, 5ATM Waterproof for Android iOS Xiaomi Phone

Note:

1. For optimal performance and accuracy, we recommend wearing the COLMI ring on your index finger. If you prefer other fingers, the middle and ring fingers are also suitable. Avoid using fingers that are narrower than the joints at the base.
2. Please measure the circumference of your finger before purchasing, and ensure that the cord or paper strip fits comfortably on your finger, avoiding it being too loose or too tight. (Please use a thinner piece of thread or paper strip to measure the size. If the measuring tool is too wide, the measurement will be large.)
3. How to start: Use the included charging box to charge the COLMI Ring. The heart rate light will illuminate to indicate a successful startup. Then you can use the Qring APP to connect to the COLMI Ring.
3.1. Some models have a protective layer on the charging port. Please remove the protective layer before charging.
3.2. If you purchase the charging case version, please charge the charging case at the same time when using it for the first time.
