 
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.
