• 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.
