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 more information, see product 
Eco-Declaration or country-specific information at www.nokia.com.
