To assure the latest available firmware is used and the E4 has the correct timestamp, you need to synchronize the E4 with the E4 manager App.
- Launch the E4 manager application on your Windows or Mac OS X computer using your E4 connect credentials.
- Connect the E4 to the computer. The E4 manager will setup your device and synchronize the internal clock with the computer’s clock.
- Unplug the E4 from the USB. You will see on the E4 wristband the flashing green and blue LED light.
