Charging the Battery
You must charge the internal battery of the Bluetooth headset before
your first use. Thereafter, the red LED will flash when the battery is
low and emit a warning sound.
A fully-charged battery will give you approximately 4.5 hours of talk time, and 100
hours stand-by time.
To charge the battery, follow the procedure below:
1.
Turn OFF the headset
2. Connect either the USB charger cable or AC adapter into the
power jack of the Bluetooth headset
3. The Red LED will remain ON while the headset is charging.
Once the headset is fully charged, the red LED will turn OFF. It
takes about 2.5 hours to fully charge the headset.
