Assemble Your Device
This section helps you to assemble your device.
Install the SIM Card and a MemoryCard
When you subscribe to a cellular network, you are provided with a
plug-in SIM card. During activation, your SIM card is loaded with your
subscription details, such as your Personal Identification Number
(PIN), available optional services, and other features.
Warning: Please be careful when handling the SIMcard to avoid
damaging it. Keep all SIM cards outof reach of small children.
You can also install an optional microSD™, microSDHC™, or
microSDXC™ memory card (notincluded) to add more memory space
to yourdevice. A memory card can be installed at any time. It is not
necessary to install it prior to using the device.
Caution: Exercise care when using the removal tool to eject the
internal SIM card/Memory card tray.
1. Insert the removal tool into the hole on the SIMcard/Memory card
tray, and then push until the tray pops out.
2. Place the SIM card on the tray.
• Make sure that the card’s gold contacts face down into the
device and that the card is positioned as shown.
3. Place the memory card on the tray with the gold contacts facing
down.

7Set Up Your Device
4. Slide the SIM card/Memory card tray back into the slot.
Note: Your device is IP68 rated for dust and water resistance. To
maintain the water-resistant and dust-resistant features of your
device, make sure that the SIM card/Memory card tray openings are
maintained free of dust and water, and the tray is securely inserted
prior to any exposure to liquids. For more information, refer to
“Maintaining Water and Dust Resistance” on page255.
Charge the Battery
Note: You should dry the inside of the charging port before inserting a
power connector to charge your device. If the charging port is not fully
dry, your device may operate abnormally. For example, it may charge
more slowly or overheat. For more information, refer to “Maintaining
Water and Dust Resistance” on page255.
Your device is powered by a rechargeable, standard Li-Ion battery.
A USB charger (charging head and USB cable) is included with the
device for charging the battery from any standard outlet.

8Set Up Your Device
The battery comes partially charged. You can use the device while
charging.
Note: For fastest charging times, use the Adaptive Fast Charger that
came with your device. This charger provides faster charging only
when connected to devices that support Adaptive Fast Charging.
1. Insert the USB cable into the USB charger/Accessory port.
Caution: Use only charging devices and batteries approved by
Samsung. Samsung accessories are designed for your device to
maximize battery life. Using other accessories may invalidate your
warranty and may cause damage.
2. Connect the USB cable to the charging head, and then plug the
charging head into a standard outlet.
3. Unplug the charging head from the outlet and remove the USB
cable from the device when charging is complete.
Note: This device is also compatible with wireless charging devices
approved by Samsung, which are soldseparately.

9Set Up Your Device
When to Charge the Battery
When the battery is low and only a few minutes of operation remain,
the device sounds a warning tone at regular intervals.
In this condition, your device conserves its remaining battery power by
dimming the screen.
When the battery level becomes too low, the device automatically
turns off.
For a quick check of your battery level:
►View the battery charge indicator located in the top right corner of
your device’s display. Asolid color ( ) indicates a full charge.
While charging, the device and the charger may become hot when
using wireless charging or fast charging. This does not affect the
device’s lifespan or performance and is in the device’s normal range of
operation.
The charger may stop charging if the battery becomes too hot.

10Set Up Your Device
If the device heats up while charging the battery:
1. Disconnect the charger from the device and close any running
apps.
2. Wait for the device to cool down, and then begin charging the
device again.
• If the lower part of the device overheats, check for damage to
the connected USB cable. Replace the damaged USB cable with
a new Samsung-approved cable.
If using a wireless charger, do not place foreign materials between the
device and the wireless charger.
Micro-USB Connector
You can use the included Micro-USB connector to connect a
Micro-USB cable (such as from your old device) to your new device for
charging with the charging head, or for connecting to a computer.
Note: The Micro-USB connector does not support On-the-Go (OTG)
devices such as memory sticks, external hard drives, or keyboard and
mouse accessories.
