Connecting the charger improperly may cause serious damage to the device. Any
damage caused by misuse is not covered by the warranty.

To save energy, unplug the charger when not in use. The charger does not have a
power switch, so you must unplug the charger from the electric socket when not in
use to avoid wasting power. The charger should remain close to the electric socket
and easily accessible while charging.

Connect the USB cable to the USB power adaptor.

1

Plug the USB cable into the device’s multipurpose jack.

2

Plug the USB power adaptor into an electric socket.

3

After fully charging, disconnect the charger from the device. Then, unplug the charger
