Maintenance
Water Resistance (IP68)
The 3Plus Callie Smartwatch is IP68 waterproof, meaning it is resistant to dust and can withstand immersion in water up to 1.5 meters for up to 30 minutes. While it is designed to be water-resistant for daily activities like hand washing or light rain, it is not recommended for swimming, showering with hot water, or diving. Avoid exposing the watch to high-pressure water or chemicals.
Cleaning and Care
To maintain your smartwatch, regularly clean the device and strap with a soft, dry cloth. If necessary, use a slightly damp cloth with mild soap and water, then dry thoroughly. Avoid using abrasive cleaners or solvents that could damage the watch's finish or sensors. Keep the charging contacts clean and free of debris.
Troubleshooting
Common Issues and Solutions

- Unable to pair with smartphone:
- Ensure Bluetooth is enabled on your phone.
- Make sure the 3Plus app is open and running.
- Restart both your smartphone and the smartwatch.
- Ensure the watch is within the Bluetooth range of your phone.
- Inaccurate health data (Heart Rate, SpO2, Sleep): Ensure the watch is worn snugly on your wrist, not too tight or too loose. Clean the sensor on the back of the watch.
- Notifications not appearing: Check notification settings within the 3Plus app and your phone's system settings to ensure permissions are granted for the app to display notifications.
