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
