Nokia 7190 Owner's Manual page 110

• Do not drop, knock or shake it. Rough handling can break internal
circuit boards.
• Do not use harsh chemicals, cleaning solvents, or strong detergents to
clean it. Wipe it with a soft cloth slightly dampened in a mild
soap-and-water solution.
• Do not paint it. Paint can clog the device's moving parts and prevent
proper operation.
• Use only the supplied or an approved replacement antenna.
Unauthorized antennas, modifications or attachments could damage
the phone and may violate regulations governing radio devices.
• If the phone, battery, charger or any accessory are not working
properly, take them to your nearest qualified service facility. The
personnel there will assist you, and if necessary, arrange for service.
