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
+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.
