3. Fall Detection with Automatic Alerts
The watch is equipped with fall detection technology. If a fall is detected, the watch will initiate a countdown. If the user does not respond within the countdown period (e.g., by pressing 'I'm Okay'), an automatic alert will be sent to pre-set emergency contacts. This ensures a rapid response in critical situations.

Maintenance
Cleaning the Watch
Regularly clean your smart watch to ensure optimal performance and hygiene. Use a soft, lint-free cloth to wipe the screen and body. For stubborn dirt, dampen the cloth slightly with water. Avoid using harsh chemicals or abrasive materials.
Battery Care
To prolong battery life, avoid fully discharging the watch frequently. Charge the device regularly, ideally before the battery level drops too low. Store the watch in a cool, dry place when not in use for extended periods.
Troubleshooting
Health Measurement Failures
If the watch displays "Failed to Measure" or provides inconsistent readings for heart rate, blood oxygen, or body composition, consider the following:
- Ensure Proper Fit: The watch should be worn snugly on your wrist, but not uncomfortably tight. The sensors on the back need good contact with your skin.
- Keep Still: Remain still during measurements. Movement can interfere with sensor accuracy.
- Clean Sensors: Ensure the sensors on the back of the watch are clean and free from dirt, sweat, or lotions.
- Finger Placement (for Body Composition): For body composition measurements, ensure your finger is correctly placed on the electrode as instructed by the watch.
Connectivity Issues
If the watch is not connecting to your smartphone via Bluetooth:
- Restart Devices: Restart both your smart watch and your smartphone.
- Check Bluetooth: Ensure Bluetooth is enabled on your phone and the watch is in pairing mode.
- App Status: Verify that the companion app is running and has the necessary permissions.
- Distance: Keep the watch and phone within Bluetooth range (typically 10 meters or 33 feet).
