• 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.
