Aircraft Safety

Please turn off your mobile phone before the airplane takes off. In order to
protect airplane's communication system from interference, it is forbidden to
use mobile phone in flight. Safety regulations require you to have permission
from a crew member to use your phone while the plane is on the ground.
If the mobile phone has the function of automatic timing power-on, please
check your alarm setting to make sure that your phone will not be
automatically turned on during flight.

Battery Use

Do not short-circuit the battery, as this can cause the unit to overheat or ignite.
Do not store battery in hot areas or throw it into fire. Otherwise, it will cause
explosion.
Do not disassemble or refit the battery. Otherwise, it will cause liquid leakage,
overheating, explosion and ignition of the battery.
Please store the battery in a cool dry place if you don't use it for a long period.
The battery can be recharged for hundreds of times, but it will eventually wear
out. When the operating time (talk time and standby time) is noticeably shorter
than normal, it is time to replace it with a new one.
Please stop using the charger and battery when they are damaged or show
evidence of aging.
