Accessories
Use the accessories delivered only by the manufacturer. Using accessories
of other manufacturers or vendors with this device model may invalidate
any approval or warranty applicable to the device, result in the
non-operation of the device, and cause danger.
Battery and Charger
Unplug the charger from the electrical plug and the device when not in
use.
The battery can be charged and discharged hundreds of times before it
eventually wears out. When the standby time and the talk time are
shorter than the normal time, replace the battery.
Use the AC power supply defined in the specifications of the charger.
An improper power voltage may cause a fire or a malfunction of the
charger.
Do not connect two poles of the battery with conductors, such as metal
materials, keys, or jewelries. Otherwise, the battery may be
short-circuited and may cause injuries and burns on your body.
Do not disassemble the battery or solder the battery poles. Otherwise, it
may lead to electrolyte leakage, overheating, fire, or explosion.
If battery electrolyte leaks out, ensure that the electrolyte does not touch
your skin and eyes. When the electrolyte touches your skin or splashes
into your eyes, wash your eyes with clean water immediately and
consult a doctor.
If there is a case of battery deformation, color change, or abnormal
heating while you charge or store the battery, remove the battery
immediately and stop using it. Otherwise, it may lead to battery leakage,
overheating, explosion, or fire.
If the power cable is damaged (for example, the cord is exposed or
broken), or the plug loosens, stop using the cable at once. Otherwise, it
may lead to an electric shock, a short circuit of the charger, or a fire.
