1. How to charge
While it’s possible that your SW 650 Pro will
already come with enough charge to be powered
on right out of the box, we recommend to fully
charge it before first use.
Press the red buttons to release and gently
pull the wristbands from the watch to free the
USB charging connector. The side with charging
contacts is labeled USB.
Insert the USB charging connector into any USB
power adapter that permits charging.
Note!
Generally charging is quicker if plugged in to a USB
power supply compared to charging via other hosts such
as computers.
