ENGLISH
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.
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, 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.
