Maintenance

To maintain the cleanliness and functionality of your fitness tracker, regularly wipe the device and band with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the device.
2. Water Resistance (IP68)
The Portzon Fitness Tracker is IP68 waterproof, meaning it is resistant to dust and can withstand immersion in water up to 1.5 meters for 30 minutes. This makes it suitable for daily hand washing, showering, and swimming in pools without needing to be removed. However, it is not recommended for hot water activities like saunas or hot tubs, or for diving.

Troubleshooting
- Device Not Turning On: Ensure the device is fully charged. Connect it to a USB power source and check if the red indicator light appears.
- Not Syncing with App:
- Ensure Bluetooth is enabled on your smartphone.
- Make sure the tracker is within Bluetooth range of your phone.
- Restart both the tracker and the Runmifit app.
- Check if the Runmifit app is updated to the latest version.
- Inaccurate Readings (Heart Rate, Blood Pressure, Sleep, Steps): While the tracker provides valuable insights, it is designed for general fitness and wellness purposes. Readings for metrics like heart rate, blood pressure, and blood oxygen are for reference only and should not be used for medical diagnosis or treatment. Step counting accuracy can be affected by arm movements not associated with walking. For precise medical measurements, consult professional medical devices.
- Short Battery Life: Ensure the device is fully charged. Reduce screen brightness, disable unnecessary notifications, or limit continuous monitoring features to extend battery life.
