•
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.
•
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.
