On the right-hand side of the unit, press both the [MENU] and the [A<-->B] button at the same time. The unit should initialize.
If nothing appears on the screen, connect it to your computer. Typically, this will bring up the screen and power on the unit, and then try to push both buttons again at the same time.
Does that help?
