Press the Power/Bluetooth® button (on top of the right earpiece) until the battery indicator glows green, yellow or red (to indicate the current battery charge level) or you hear the power-up tones.
Press and hold the Power/Bluetooth® button until the battery indicator blinks three times and turns off. You will hear the power-down tones. Then release the Power/Bluetooth® button.
Note: Continuing to hold down the Power/Bluetooth button after hearing the power-down tones will put the headset in discoverable mode. Be sure to release the power button immediately after hearing the tones to power off the headset.
