•
Do not disassemble, crush, puncture, shred, or otherwise
attempt to change the form of your battery. Do not put a high
degree of pressure on the battery. This can cause leakage or an
internal short-circuit, resulting in overheating.
•
Do not let the phone or battery come in contact with liquids.
Liquids can get into the phone's circuits, leading to corrosion.
Even when the phone appears to be dry and appears to operate
normally, the circuitry could slowly corrode and pose a safety
hazard. If the phone and/or battery get wet, have them checked
by your service provider or contact Samsung, even if they appear
to be working properly.
•
Do not place your battery in or near a heat source. Excessive
heating can damage the phone or the battery and could cause the
phone or the battery to explode. Do not dry a wet or damp battery
with an appliance or heat source such as a microwave oven, hair
dryer, iron, or radiator. Avoid leaving your phone in your car in
high temperatures.
•
Caution: Some applications or prolonged usage may increase
device temperature. Prolonged skin contact with a device that is
hot to the touch may produce skin discomfort or redness, or low-
temperature burns. If the device feels hot to the touch,
discontinue use and close all applications or turn off the device
until it cools. Always ensure that the phone has adequate
ventilation and air flow. Covering the device with bedding, your
body, thick clothing or any other materials that significantly affect
air flow may affect the performance of the phone and poses a
possible risk of fire or explosion, which could lead to serious
bodily injuries or damage to property.
•
Do not dispose of the phone or the battery in a fire. The phone
or the battery may explode when overheated.
•
Do not handle a damaged or leaking battery. Do not let leaking
battery fluid come in contact with your eyes, skin or clothing. For
safe disposal options, contact your nearest Samsung-authorized
service center.
•
Avoid dropping the cell phone. Dropping the phone or the
battery, especially on a hard surface, can potentially cause
damage to the phone and battery. If you suspect damage to the
phone or battery, take it to a service center for inspection.
•
Never use any charger or battery that is damaged in any way.
