Storage Environment
Do not place magnetic storage media such as magnetic cards and floppy disks near the terminal. Radiation from the
terminal may erase the information stored on them.
Do not put the terminal, battery, or charger in containers with a strong electromagnetic field, such as an induction cooker
and a microwave oven. Otherwise, circuit failure, fire, or explosion may occur.
Do not leave the terminal, battery or charger in a very hot or cold place. Otherwise, malfunction of the terminal, fire or
explosion may occur.
Keep the ambient temperature between 0 ℃ and 45 ℃ while the terminal is being charged. Keep the ambient
temperature between -20℃ and 60℃ for storing the battery. Extreme temperatures may reduce the capacity and
lifetime of the battery. Battery performance is particularly limited in temperatures below 0℃.
Do not place sharp metal objects such as pins near the earpiece. The earpiece may attract these objects and hurt you
when you are using the terminal.
Do not subject the terminal, battery, and charger to serious collision or shock. Otherwise, battery leakage, terminal
malfunction, overheat, fire, or explosion may occur.
Do not put the terminal in the back pocket of your trousers or skirt, to avoid terminal damage while seated.
Operating Environment
Do not use the terminal in dusty, damp, and dirty places or places with magnetic fields. Otherwise, malfunction of the
circuit may occur.
Do not turn on or off the terminal when it is near your ears to avoid negative impact on your health.
When carrying or using the terminal, keep the antenna at least one inch (2.5 centimeters) away from your body, to avoid
negative impact on your health caused by radio frequency leakage.
Move the terminal away from your ear while using the "hands-free" mode as the amplified volume might cause hearing
damage.
Do not let the flashlight close to your eyes when taking photos.
On a thunder stormy day, do not use the terminal outdoors or when it is being charged, to prevent any danger caused
by lightning.
The terminal may interfere with nearby TV sets, radios and PCs.
In accordance with international standards for radio frequency and radiation, use terminal accessories approved by the
manufacturer only.
While using the terminal, observe the local laws and regulations, and respect others' privacy and legal rights.
Cleaning and Maintenance
Before cleaning or maintaining the terminal, turn off the terminal and disconnect it from the charger. Otherwise, electric
shock or short-circuit of the battery or charger may occur.
