Nokia 9251888/1 ユーザーズマニュアル

• 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.
