Charge the battery
Before using the device for the first time or when the battery 
has been unused for an extended period, you must charge 
the battery. You can charge the battery with a travel adapter 
or by connecting the device to a computer with a USB cable.
Use only Samsung-approved chargers and cables. 
Unapproved chargers or cables may cause batteries to 
explode or damage your device.
When your battery is low, the device will emit a  
●
warning tone and show a low battery message. 
Recharge your battery to continue using your device.
If the battery is completely discharged, you cannot 
 
●
turn on the device, even with the travel adapter 
connected. Allow a depleted battery to charge for a 
while before you try to turn on the device.
If you use multiple applications at once, network 
 
●
applications, or applications that need a connection 
to another device, the battery will drain quickly. To 
avoid disconnecting from the network or losing 
power during a data transfer, always use these 
applications after fully charging the battery.

connected to the travel adapter. Doing so may damage 
the device.

socket when not in use to avoid wasting power. The 
device should remain close to the electrical socket while 
charging.

Before charging, ensure that your computer is turned on.Plug the small end (micro-USB) of the USB cable into the 
1 
multifunction jack.

it may take some time before charging begins.

3 
cable from the device, and then from the computer.

Insert a memory card (optional)
Your device accepts microSD™ or microSDHC™ memory 
cards with maximum capacities of 32 GB (depending on the 
memory card manufacturer and type).
Samsung uses approved industry standards for memory 
cards, but some brands may not be fully compatible 
with your device. Using an incompatible memory card 
may damage your device or the memory card. It may 
also corrupt data saved on the memory card.
Your device supports only the FAT file structure for  
●
memory cards. If you insert a memory card formatted 
with a different file structure, your device will ask you 
to reformat the memory card.

●
lifespan of your memory cards.
