4. Battery information
Your headset is powered by a rechargeable battery. Take good care of
the battery and follow the guidelines below.
■ Charging and Discharging
The battery can be charged and discharged hundreds of times but it will
eventually wear out. When the operating time (talk time and standby
time) is noticeably shorter than normal, it is time to buy a new battery.
Use only batteries approved by the manufacturer and recharge your
battery only with the chargers approved by the manufacturer. Unplug
the charger when not in use. Do not leave the battery connected to a
charger for longer than a week, since overcharging may shorten its
lifetime. If left unused a fully charged battery will discharge itself over
time.
Temperature extremes can affect the ability of your battery to charge.
Use the battery only for its intended purpose.
Never use any charger or battery which is damaged.
Do not short-circuit the battery. Accidental short-circuiting can occur
when a metallic object (coin, clip or pen) causes direct connection of the
+ and - terminals of the battery (metal strips on the battery), for
example, when you carry a spare battery in your pocket or purse. Short-
circuiting the terminals may damage the battery or the connecting
object.
Leaving the battery 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 temporarily not
work, even when the battery is fully charged. Batteries' performance is
particularly limited in temperatures well below freezing.
Do not dispose of batteries in a fire!
Dispose of batteries according to local regulations (e.g. recycling). Do
not dispose as household waste.
