Synchronize your E4 wristband for the first time

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.
