Size chart for Smart Rings showing inner diameter and perimeter for sizes #7 through #12, and a two-step method for measuring finger size using a string and ruler.

Figure 4.1: Smart Ring Size Chart and Measuring Finger Method. It is recommended to measure your finger accurately to ensure proper fit and data accuracy.

Step 1: When measuring, choose a thin, non-stretchy wire or string and wrap it around your finger. Mark the point where the string overlaps with a pen or other tool.
Step 2: Straighten the marked wire/string and measure its length with a ruler. Compare this measurement to the "Perimeter" column in the size chart to find your corresponding ring size.

Once your Smart Ring is charged and paired with the "Smart Health" app, you can begin monitoring your health and fitness data.

5.1. Health Monitoring (Heart Rate, Blood Pressure, SP-O2)

The ring continuously monitors your heart rate. For on-demand blood pressure and SP-O2 readings, open the "Smart Health" app and navigate to the respective monitoring sections.
Ensure the ring is worn snugly on your finger for accurate readings.

5.2. Sleep Monitoring

Cleaning: Wipe the ring regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying.
Water Exposure: While the ring is IP68 waterproof and can withstand swimming, washing hands, and cold showers, it is not suitable for hot water, diving, or prolonged submersion in hot environments (e.g., saunas, hot tubs).
Drying After Water Exposure: After swimming or getting wet, shake off excess water and wipe the ring dry to prevent water spots and ensure sensor accuracy.
Storage: Store the ring in a cool, dry place when not in use. Avoid extreme temperatures.

7. Troubleshooting

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

Problem	Possible Cause / Solution
Inaccurate Data (Heart Rate, Blood Pressure, Sleep)	Ring is too loose: Ensure the ring fits snugly on your finger. A loose fit can significantly impact sensor accuracy. Refer to Section 4.3 for sizing. Improper wearing position: Ensure the sensors on the inside of the ring are in good contact with your skin. Movement during measurement: Try to remain still during spot measurements. Environmental factors: Extreme temperatures or excessive moisture can affect readings.
Ring Disconnects from App Frequently	Bluetooth range: Ensure your ring is within Bluetooth range of your smartphone (typically 10 meters/33 feet). App running in background: Ensure the "Smart Health" app is running in the background and not being closed by your phone's operating system. Low battery: Charge the ring fully. Bluetooth interference: Move away from other strong wireless signals. Restart devices: Try restarting both your smartphone's Bluetooth and the Smart Ring (if applicable, by placing it on the charger).
Ring Not Charging	Cable connection: Ensure the magnetic charging cable is properly aligned with the charging points on the ring and securely connected to a power source. Power source: Try a different USB port or wall adapter. Clean contacts: Gently clean the charging contacts on both the ring and the cable with a dry cloth to remove any dust or debris.
App Not Syncing Data	Bluetooth connection: Verify the ring is connected to the app via Bluetooth. App permissions: Check if the "Smart Health" app has necessary permissions (e.g., Bluetooth, location) enabled in your phone's settings. Update app: Ensure you have the latest version of the "Smart Health" app installed. Restart app: Close and reopen the app.
