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
