Samsung SPH-A420 User Manual page 94

• 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.
• 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, stove, or radiator. The phone may explode
when overheated.
• When the phone or battery gets wet, the label indicating water
damage inside the phone changes colour. 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.
Unauthorised 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.
