  2. Feed the large loop of the lanyard back through the small loop and pull through. Complete.


Before first use, please fully charge MT330. Connect the provided USB cable into a computer's USB port or plug the cable into a 5V USB Power Adapter and plug it into a AC (Mains) power outlet and turn on. Now connect the micro USB end of the cable into MT330. MT330 will turn on when charging, this is normal. A full battery charge will take approximately 3 hours.
