Assembling

Connecting the travel adapter improperly may cause
serious damage to the device. Any damage caused by
misuse is not covered by the warranty.
Plug the large end of the travel adapter into a power
3
outlet.
You can use the device while it is charging, but it may
●
take longer to fully charge the battery.
While the device is charging, the touch screen may
●
not function due to an unstable power supply. If this
happens, unplug the travel adapter from the device.
While charging, the device may heat up. This is
●
normal and should not affect your device’s lifespan or
performance.
If your device is not charging properly, bring your
●
device and the charger to a Samsung Service Centre.
When the battery is fully charged, first unplug the travel
4
adapter from the device and then from the power outlet.
Do not remove the battery before removing the travel
adapter. Doing this may cause damage to the device.
To save energy, unplug the travel adapter when not in
use. The travel adapter does not have a power switch,
so you must unplug the travel adapter from the outlet
to interrupt the power supply. The travel adapter should
remain close to the socket when in use.
