Your headset is powered by a rechargeable battery. Take good care of the
battery and follow the guidelines below.
Charging and discharging
• Note that a new battery's full performance is achieved only after two
or three complete charge and discharge cycles!
• The battery can be charged and discharged hundreds of times but it
will eventually wear out. When the operating time is noticeably
shorter than normal, it is time to buy a new battery.
• Use only batteries approved by Nokia and recharge your battery only
with the chargers approved by Nokia. 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.
• For good operation times with NiMh batteries, discharge the battery
from time to time by leaving your headset switched on until it turns
itself off. Do not attempt to discharge the battery by any other means.
• Use the battery only for its intended purpose.
• Never use any charger or battery which 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
