Your headset is powered by a rechargeable battery. Take good care of the battery 
and follow the guidelines below.

■ Charge and Discharge

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, contact your nearest qualified service facility.

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 that 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
