Do not use any other adapters other than the power supply device (5V/3A)
enclosed in the original purchase. Connect the power supply device in a way
the DC 5V sticker faces upwards.
On the other hand, if you plug in using excessive force, it may result in
problems that need customer-service. In that case, the Company cannot
provide any customer-service, either free repair or replacement as it is
caused by users‟ inadvertence.
When you charge the device in the cradle, insert the plug into the charge jack
with two fingers until „click‟ sound is heard as shown in the backside picture
of [charge in the cradle] above. When the device is completely discharged,
plug in the adapter and reset it to check if the LCD is on. Then, charge it for
at least 10 minutes before use.
