3 I BLUETREK DUO Stereo
Important:
• If your headset is fully charged, the red indicator light will not turn on when plugging into
the charger.
• To maximize battery lifetime, it is recommended to recharge your headset to full capacity
only when the battery is low, since a battery 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 2 hours or more until the battery
recovers and recharges completely. When you first charge the headset after prolonged stor-
age, it may take few minutes for the red indicator light to turn on.
• Do not charge your headset for more than 10 hours.
• The use of any other charger will automatically suspend the warranty. It is strictly forbidden
and can be very dangerous.
