When installing the battery, do not push the battery by force lest
battery fluid leak out or the battery crack.
Do not take out the battery when the phone is turned on.

Charger
Use the charger approved by the phone manufacturer only. Any
violation of this rule may result in fire or malfunction of the
charger.
Do not short-circuit the charger. Short-circuiting the charger may
cause fire or malfunction of the charger.
If the power cord is damaged (for example, the lead is exposed or
broken), or the plug becomes loose, stop using the cable at once.
Otherwise, electric shock, short-circuit of the charger, or fire may
occur.
Keep the charger dry. Once water or other liquid leaks into the
charger, electrical leakage or other faults may occur.
Do not use the charger in a dusty and damp environment. Keep
the power cord away from any heating appliance.
Ensure the charger is properly plugged into the power socket
properly when charging the battery. Improper insertion may result
in electric shock, fire, or explosion. To unplug the charger, pull
the plug off rather than tear the power cord.
Use the AC power supply defined in the specifications of the
charger. An improper power voltage can cause fire or malfunction
of the charger.
Do not place any heavy object on the power cord of the charger.
Do not damage, change, or pluck the power cord. Otherwise
electric shock or fire may occur.
