Nokia BH-304 ユーザーズマニュアル

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, allow it to 
dry completely.

• 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.

• 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.

All of the above 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.
