It is suitable for daily use and can be worn during activities like swimming. However, it is not recommended for hot showers, saunas, or diving, as steam and high pressure can compromise the seals.

Cleaning
To maintain your smartwatch, regularly clean the screen and strap with a soft, dry, lint-free cloth. If necessary, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
Battery Care
To prolong battery life, avoid fully discharging the watch frequently. Charge it regularly, especially if you plan not to use it for an extended period.
Troubleshooting
Connectivity Issues
- Watch not connecting to phone: Ensure Bluetooth is enabled on your phone and the watch is within range. Restart both the watch and your phone. Check if the 'COLMI Fit' app is running in the background and has necessary permissions.
- Call/Message notifications not working: Verify that notification access is granted to the 'COLMI Fit' app in your phone's settings. Check the app's settings to ensure notifications are enabled for desired applications.
Inaccurate Health Readings
- Heart Rate/SpO2: Ensure the watch is worn snugly on your wrist, not too tight or too loose. The sensors on the back of the watch should be in direct contact with your skin. Avoid excessive movement during measurements.
- Sleep Tracking: Ensure you wear the watch while sleeping. The accuracy can be affected by how loosely the watch is worn or if you remove it during the night.
Battery Draining Quickly
- Frequent usage of features: Constant use of Bluetooth calling, GPS (if available), or bright display settings can consume more battery.
- Background app activity: Ensure unnecessary apps are closed on your phone that might be constantly syncing with the watch.
- Screen brightness: Lower the screen brightness to conserve power.
Watch Not Turning On

- Hard reset: If unresponsive, try pressing and holding the side button for an extended period (e.g., 10-15 seconds) to force a restart.
