Nokia BH-301 ユーザーズマニュアル

connected to a charger, since 
overcharging may shorten its lifetime. If 
left unused, a fully charged battery will 
lose its charge over time.

Never use any charger that is damaged.

Leaving the headset in hot or cold places, 
such as in a closed car in summer or 
winter conditions, will reduce the 
capacity and lifetime of the battery. 
Always try to keep the battery between 
15°C and 25°C (59°F and 77°F). A headset 

with a hot or cold battery may not work 
temporarily, even when the battery is 
fully charged. Battery performance is 
particularly limited in temperatures well 
below freezing.

Do not dispose of batteries in a fire as 
they may explode. Batteries may also 
explode if damaged. Dispose of batteries 
according to local regulations. Please 
recycle when possible. Do not dispose as 
household waste.

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.
