• Keep the phone and all its parts and accessories out of the
reach of small children.
• Keep the phone dry. Precipitation, humidity and liquids
contain minerals that will corrode electronic circuits.
• Do not use the phone with a wet hand. Doing so may cause
an electric shock to you or damage to the phone.
• 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.
• If your phone is equipped with an external antenna, 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.
