 Do not use or store the phone in dusty, dirty areas, as its moving
parts may be damaged.
 Do not store the phone in hot areas. High temperatures can
shorten the life of electronic devices, damage batteries, and warp
or melt certain plastics.
 Do not store the phone in cold areas. When the phone warms up to
its normal operating temperature, moisture can form inside the
phone, which may damage the phone's electronic circuit boards.
 Do not drop, knock or shake the phone. Rough handling can break
internal circuit boards.
 Do not use harsh chemicals, cleaning solvents or strong detergents
to clean the phone. Wipe it with a soft cloth slightly dampened in a
mild soap-and-water solution.
 Do not paint the phone. Paint can clog the device's moving parts
and prevent proper operation.
 Do not put the phone in or on heating devices, such as a
microwave oven, a stove or a radiator. The phone may explode
when overheated.
 When the phone or battery gets wet, the label indicating water
damage inside the phone changes color. In this case, phone repairs
are no longer guaranteed by the manufacturer's warranty, even if
the warranty for your phone has not expired.
 If your phone has a flash or light, do not use it too close to the
eyes of people or animals. This may cause damage to their eyes.
 Use only the supplied or an approved replacement antenna.
Unauthorized antennas or modified accessories may damage the
phone and violate regulations governing radio devices.
 If the phone, battery, charger or any accessory is not working
properly, take it to your nearest qualified service facility. The
personnel there will assist you, and if necessary, arrange for
service.
