Charging the battery
Charge the battery before using it for the first time or when it has been unused for extended
periods.
Use only Samsung-approved battery, charger, and cable specifically designed for your
device. Incompatible battery, charger, and cable can cause serious injuries or damage
to your device.
• Connecting the charger improperly may cause serious damage to the device. Any
damage caused by misuse is not covered by the warranty.
• Do not remove the battery before removing the charger. This may damage the
device.
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.
1
Connect the USB cable to the USB power adaptor.
