Nokia E51 - Manual (Page 48)

Care and maintenance
Your device is a product of superior design and craftsmanship and should be
treated with care. The following suggestions 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.
• 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.
• To reset the device from time to time for optimum performance, power
off the device and remove the battery.
These suggestions apply equally to your device, battery, charger, or any
enhancement. If any device is not working properly, take it to the nearest
authorized service facility for service.
Disposal
The crossed-out wheeled-bin symbol on your product, literature, or
packaging reminds you that in the European Union all electrical and
electronic products, batteries, and accumulators must be taken to
separate collection at the end of their working life. Do not dispose of
these products as unsorted municipal waste.
Return the products to collection to prevent possible harm to the
environment or human health from uncontrolled waste disposal and to
promote the sustainable reuse of material resources. Collection information
is available from the product retailer, local waste authorities, national
producer responsibility organizations, or your local Nokia representative. For
