To charge your headset, plug the charger into the headset's micro USB port.

When you are not in a call, press the Volume Up and Volume Down buttons to hear how much battery talk-time is left on your headset. 

The status light can also be used to determine remaining talk-time.

Green = over 4 hours talk-time
Yellow = 2-3 hours talk-time
Red = under 1 hour talk-time 

Tips:

• To save battery power, turn off the headset when you are not using it.
• While your headset is charging, you won’t be able to use it.

Notes:

• Fully charge the headset before you use it.
• Your battery is designed to last the life of your product. It should only be removed by a recycling facility. Any attempt to remove or replace your battery will damage your headset.
