Nokia BH-109 Bluetooth Headset User Manual


 
If a battery is being used for the first time or if the battery has not been used for a prolonged period, it may be necessary to
connect the charger, then disconnect and reconnect it to begin charging the battery. If the battery is completely discharged, it
may take several minutes before the charging indicator light is displayed.
When your charger is not in use, unplug it from the electrical plug and the device. Do not leave a fully charged battery connected
to a charger, as overcharging may shorten the battery’s lifetime. If left unused, a fully charged battery will lose its charge over
time.
Always keep the battery between 15°C and 25°C (59°F and 77°F). Extreme temperatures reduce the capacity and lifetime of the
battery. A device with a hot or cold battery may not work temporarily.
Do not dispose of batteries in a fire as they may explode. Dispose of batteries according to local regulations. Recycle when
possible. Do not dispose as household waste.
Never use any charger that is damaged.
Operating times are estimates only. Actual performance depends on many factors such as device settings selected, device
features being used (or running in the background), battery condition and ambient temperature.
Take care of your device
Handle your device, battery, charger and accessories with care. The following suggestions help you protect your warranty
coverage.
Keep the device dry. Precipitation, humidity, and all types of liquids or moisture can contain minerals that corrode
electronic circuits.
Do not use or store the device in dusty or dirty areas. Moving parts and electronic components can be damaged.
Do not store the device in high temperatures. High temperatures can shorten the life of the device, damage the battery,
and warp or melt plastics.
Do not store the device in cold temperatures. When the device warms to its normal temperature, moisture can form inside
the device and damage electronic circuits.
Do not attempt to open the device.
Unauthorised modifications may damage the device and violate regulations governing radio devices.
Do not drop, knock, or shake the device. Rough handling can break internal circuit boards and mechanics.
Only use a soft, clean, dry cloth to clean the surface of the device.
Do not paint the device. Paint can clog the moving parts and prevent proper operation.
Recycle
Always return your used electronic products, batteries, and packaging materials to dedicated collection points. This way you
help prevent uncontrolled waste disposal and promote the recycling of materials. Check product environmental information
and how to recycle your Nokia products at www.nokia.com/werecycle, or with a mobile device, nokia.mobi/werecycle.
Crossed-out wheeled-bin symbol
The crossed-out wheeled-bin symbol on your product, battery, literature, or packaging reminds you that all electrical and
electronic products, batteries, and accumulators must be taken to separate collection at the end of their working life. This
requirement applies in the European Union. Do not dispose of these products as unsorted municipal waste. For more information
on the environmental attributes of your device, see www.nokia.com/ecodeclaration.
