Before using the headset, charge the battery using a USB-micro B cable. When the battery charge is low, the headset beeps and a red indicator light flashes.
When the headset is connected to the device, the blue indicator light flashes. You can pair the headset with 8 compatible devices, but you can only connect it to a maximum of 2 devices at the same time. The next time you switch the headset on, it automatically connects to the last connected device. With some devices, you may need to make the connection separately after pairing.
