The wrench symbol and a code of -02 refers to an error produced by your tracker's heart rate sensor. This can simply be resolved by restarting your tracker as follows:
How to restart
- Open the VeryFitPro app
- Navigate to Device > More > Reboot the device and tap Confirm to Reboot
- The app will perform a sync and your tracker will restart. Once the operation is complete your tracker will vibrate and you will see Reboot Done briefly within the VeryFitPro app
If after performing the above you continue to see the wench and -02 code, please contact our support team for further assistance.
