Turn the main volume control and the bass level knob to the lowest setting before switching on the power to your 2.1 UltraSonic™ Speaker System. (Turn the knobs counter- clockwise.) Turn the power knob clockwise to switch on the power. (The blue LED will illuminate when the power is switched on).
Turn on your computer (or portable audio device). Open your media player such as Windows Media Player®, Music Match Jukebox®, etc. Click on play to start playing your music.
Adjust the volume and bass to a comfortable listening level. Make sure the volume on your speaker system, in your music software, and the main volume control in your operating system are all at an audible level (if any one of these volume levels are at its lowest setting, you will not have sound coming from the speakers).
