Connect the H2 to the computer. Using a standard USB cable, plug one end to a free USB port on your computer. Connect the other end to the USB port on your H2. The USB port is on the bottom right hand side of the H2. Ensure your H2 is on before proceeding.
Press the "Menu" button on the front of the H2. Using the "Rewind" (REW) and "Fast-Forward" (FF) buttons on the front of the H2, navigate to the USB screen on the H2 display.
Press the "Record" (REC) button on the front of the H2. Your computer will now recognize the device as an audio interface.
Select "Connect" by using the "Rewind" and "Fast Forward" buttons to scroll left and right. This will display the "USB Audio I/F" screen. You can set your recording levels from this screen. Use the "Rewind" and "Fast-Forward" buttons to select input sensitivity and recording levels.
Disconnect the connection after recording by scrolling to "Exit" on the "USB Audio I/F' screen and pressing the "Record" button. This will cancel the connection to the computer. Remove the USB cable from the computer and the H2.
