Environment Protection
Follow all the local regulations regarding the disposal of your devices or electrical accessories (such as chargers,
headsets, or batteries). Recycle them. Do 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.
If the ambient temperature is considerably low or high, the capacity and life of the battery is reduced. When
the temperature is lower than 0°C, performance of the battery is affected.
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.
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, make sure 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 the battery is damaged, or the color changes or gets abnormally heated 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 lead is exposed or broken), or the plug loosens, stop using the
cable at once. Otherwise, it may lead to electric shock, short-circuit of the charger, or a fire.
Do not dispose of batteries in fire as they may explode. Batteries may also explode if damaged.
