It is normal that your wireless device gets hot when you use or charge it. Before you clean
or maintain the wireless device, stop all applications, power off the device and disconnect
it from the charger and your PC.
The device, battery, and charger are not water-resistant. Keep them dry. Protect the
device, battery, and charger from water or vapor. Do not touch the device or the
charger with a wet hand. Otherwise, it may lead to a short circuit, a malfunction of the
device, and an electric shock to the user.
Do not place your device, battery, and charger in places where they can get damaged
because of collision. Otherwise, it may lead to battery leakage, device malfunction,
overheating, fire, or explosion.
Do not place magnetic storage media such as magnetic cards and floppy disks near
the device. Radiation from the device may erase the information stored on them.
Do not leave your device, battery, and charger in a place with an extreme high or low
temperature. Otherwise, they may not function properly and may lead to a fire or an
explosion. When the temperature is lower than 0°C, performance of the battery is
affected.
