8) Turn your phone off and do not remove its battery or charge the battery when in an area with
a potentially explosive atmosphere. Sparks in such areas could cause an explosion or fire
resulting in property damage, bodily injury or even death. For example: switch off the phone
before entering refueling point. Do not use the phone near at a refueling point (service
station) or near fuels or chemicals.
9) Keep your phone away from moisture. If water or other liquids get into phone, it will cause
phone overheating, leakage of electricity and malfunction.
1.1.3 Battery Safety Precautions
1) Battery Precautions
Do not throw a battery into a fire. A battery may rupture or bum violently when thrown into
a fire. Please dispose of the used battery according to your local environmental laws.
When installing battery, do not forcibly put pressure on the battery, or it may result in
overheating, leaking, rupturing or fire.
Do not short-circuit the positive (+) and negative (-) terminals. If the positive and negative
terminals come into contact with each other or are shorted with wire or other metallic
objects, an instantaneous high current will flow, possibly damaging the battery structure
due to the generated heat, with the possible result of overheating, leaking, rupturing or fire.
Do not exceed the battery manufacturer's charging current or voltage limitations.And only
use the approved peripherals.
Do not directly solder anything onto the battery terminals. Direct soldering onto the battery
terminals can cause heat generation, leaking, rupturing or fire.
If the electrolyte inside the battery gets into your eyes, it may blind you. In such case, do
not rub your eyes but rinse with a large quantity of water immediately and consult a doctor.
For safety, do not put the battery into your mouth or use the damaged battery.
Do not attempt to disassemble or modify a battery. Doing so may result in leaking,
overheating, rupture or fire.
Do not use or put battery near high temperature places like fire or heat-generating parts,
or it may cause leaking, overheating, rupture or fire.
Stop using the battery if abnormal heat, odor, discoloration, deformation, or abnormal
conditions are detected during use, charge, or storage.
Do not allow leaked electrolyte to come into contact with your skin or clothes. If this
happens, rinse with a large quantity of water immediately and consult a doctor.
If the battery leaks electrolyte or emits a strange odor, immediately remove it from open
flame to avoid fire and rupture.
Keep battery from moisture, as it may cause the battery to overheat, smoke and corrode.
Do not place or store the battery in an automobile in hot weather, under direct sunlight.
Use or storage of the battery in these places may cause battery leakage and overheating,
and possibly lower the performance and shorten the battery's life.
Only use the approved batteries and fittings. Do not connect to unspecified devices.
Do not continuously charge the battery for more than 24 hours, as battery may be
damaged by extensive overcharging.
2) Battery Capability
Calling, backlight on and playing game drain your battery much quicker. Long talk-time
decreases the duration of the standby time.
Idle time becomes shorter if the phone is out of coverage.
Battery capability varies along with charging level, temperature, signal strength, and
backlight.
1.1.4 Disposing of Used Battery
The rechargeable batteries contain toxic heavy metals like mercury, cadmium, and lead.
