Charge your headset before using. Plug in your headset and 
place on a flat non-metallic surface. The Smart Sensors in your 
headset fully calibrate while charging. When fully charged the LED 
goes off. 

Check Battery Level and Smart Sensor
To check the battery status, the headset must be powered on. While wearing the headset short 
press power button and a voice alert will advise you of the talk time you have remaining on 
your current charge. If you hear a beep after the remaining talk time your Smart Sensors are 
not calibrated properly. Remove headset from your ear and place headset flat on a non-metallic 
surface and connect to the AC charger or the USB cable charger for 10 seconds to recalibrate 
the Smart Sensors. While not wearing your headset short press the power button and the 
indicator light flashes red to show the battery charge level as shown below.
