Battery installation

The battery is permanently attached to the battery compartment
cover. Do not try to separate them from each other. After installing
the battery, charge it for at least 15 minutes. You may be able to
make and receive short calls. For optimal performance, charge the
headset battery for at least three hours before use. When fully
charged, the headset battery provides approximately 12 hours of
talk time or 5 days of standby time. When the headset is not in
use, recharge it by returning it to the headset charger.
1. Insert the battery into the
battery compartment.
2. Press down on the battery until it
clicks into place.
NOTES:
Remove any headset attachment, except the earbud, before battery
