Charging the headset battery
If you charge the battery for the first time, allow charging for at least 3 hours without interruption. Later, 2.5
hours will suffice to fully charge the battery.
A fully charged battery provides a playback time of up to 7.5 hours or a standby time of up to 220 hours.
When the battery is about to run flat:
• All indications of the LED

turn red.
• A low battery warning (three beeps) is heard in the headset.
• You have several minutes of battery reserve. When the battery is empty, you first hear the three warning
beeps and then a descending sequence of tones in the headset. The headset switches off.
