■ Charging the battery
1. Connect the charger cable to the headset as shown in
Figure 3.
2. Connect the charger to a wall outlet. The red indicator
light is displayed during charging. If the battery is
completely discharged, it may take a few minutes before
the red indicator is shown. Charging the battery fully
may take up to 2 hours depending on the charger.
3. When the battery is fully charged, the green indicator
light is displayed. Disconnect the charger from the wall
outlet and the headset.
The fully charged battery has power for up to 7 hours of talk-time or up to 180
hours of standby time. (In the standby mode, the paired headset is switched on
but no call is in progress.)
When the battery is running out of power, the headset beeps, and the red
indicator light starts to blink. Charge the battery as described above.
