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.
• 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.
