electrical socket.
If the device receives an unstable power supply
while charging, the touch screen may not function.
If this happens, unplug the travel adapter from the
device.
3. When the battery is fully charged, first unplug the
travel adapter from the device, and then from the
electrical socket.
Do not remove the battery while the device is
connected to the travel adapter. Doing so may
damage 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 electrical socket when not in use to avoid
wasting power. The device should remain close to
the electrical socket while charging.
