Important:
• To maximize battery lifetime, it is recommended that you recharge your headset to full
capacity only when the battery is low, as it has a lifetime of about 500 charging cycles.
• If you leave your headset battery empty for an extended period of time, it could
excessively discharge the battery. In this case, charge your headset for 10 hours or more
until the battery recovers and recharges completely. Switch the headset on only when
the green indicator light goes o , indicating that the battery has fully recovered.
• Do not let the battery charger remain plugged in the headset for more than 24h.
