When you first receive the device it will be unlocked so no passcode will be needed. Just plug in the device and go to "my computer". Double click on it there and you will find a PDF file located on the drive. This PDF file has full directions on how to use the device.
Also, we would recommend dragging the directions to your desktop or another safe place on your computer. This way, if something happens, you can get to the directions easily.
You can also get a copy of the directions by clicking here.
