Charge the battery
The headset has been charged at the factory, but you may want to recharge it before you switch the headset on for the first time.
Put the headset in the charging adapter.
Connect the adapter to a USB port on your computer, or to a compatible charger. The lights in the battery indicator blink slowly when your headset is being charged.
When the indicator lights stop blinking, the battery is fully charged.
The fully charged battery has power for up to 6 hours of talk time. The standby time is up to 12–15 days. When in the carrying clip, the standby time is up to 3 months.
When the battery charge is low, the frame around the battery indicator blinks.
Make sure the headset is on, then swipe your finger over the battery indicator. The three white indicator lights show the battery level. If the headset is in your ear, a voice prompt tells you the remaining talk time.
You can charge your headset also without the charging adaptor. Use a compatible USB cable to connect the headset to your computer or a charger.
When you unplug a charger, hold and pull the plug, not the cord.
