Nokia 7390 - Care and maintenance

Care and maintenance

Your device is a product of superior design and craftsmanship and should be
treated with care. The suggestions below will help you protect your warranty
coverage.

• Keep the device dry. Precipitation, humidity and all types of liquids or

moisture can contain minerals that will corrode electronic circuits. If your
device does get wet, remove the battery and allow the device to dry
completely before replacing it.

• Do not use or store the device in dusty, dirty areas. Its moving parts and

electronic components can be damaged.

• Do not store the device in hot areas. High temperatures can shorten the

life of electronic devices, damage batteries, and warp or melt certain
plastics.

• Do not store the device in cold areas. When the device returns to its

normal temperature, moisture can form inside the device and damage
electronic circuit boards.

• Do not attempt to open the device other than as instructed in this guide.

• Do not drop, knock, or shake the device. Rough handling can break

internal circuit boards and fine mechanics.

• Do not use harsh chemicals, cleaning solvents, or strong detergents to

clean the device.

• Do not paint the device. Paint can clog the moving parts and prevent

proper operation.

• Do not touch the main display with hard or angular materials. Objects like

earrings or jewellery may scratch the display.

• Use a soft, clean, dry cloth to clean any lenses (such as camera, proximity

sensor, and light sensor lenses).

• Use only the supplied or an approved replacement antenna. Unauthorized

antennas, modifications, or attachments could damage the device and may
violate regulations governing radio devices.

• Use chargers indoors.

• Always create a backup of data you want to keep (such as contacts and

calendar notes) before sending your device to a service facility.
