not dispose of an exhausted battery or a used device
in a garbage can.
Accessories
Use only the accessories, such as the charger, battery,
and headset, delivered by manufacturer. Using
accessories of other manufacturers or vendors with
this device model might invalidate any approval or
warranty applicable to the device, might result in the
non-operation of the device, and might be dangerous.
Battery and Charger
The battery can be charged and discharged
hundreds of times before it eventually wears out.
When the standby time and talk time are shorter
than normal, replace the battery.
Use the AC power supply defined in the
specifications of the charger. An improper power
voltage may cause fire or the charger may not
function properly.
Do not connect two poles of the battery with
conductors such as metal materials, keys or
jewelries. Otherwise, the battery may be
short-circuiting and may cause injuries and burns
on your body.

leakage, overheating, fire, or explosion.
