We recommend plugging your power cable into a USB port on your computer or other low-power source.
If you wish, you can use a certified wall charger to charge your device.
To charge your ZeRound2, please follow these instructions:
1) Secure the charging cradle under the watch and make sure the base terminals are aligned with the charging contacts on the back of the ZeRound2.
2) Plug the charging cable into a USB port on your computer or into a USB wall charger.
3) Connect the other end of the charging cable to the port on the charging cradle. The charging cable pins must be firmly locked in the port.
4)After the connection is made, a battery icon will appear on the screen after a few seconds.
Good to know:
A full charge lasts about 1h30.
As soon as the battery level is low, a low battery indicator appears from time to time.
