Turning the LCD on.
Using the LCD touch screen is easy. Simply touch the
screen to activate it. The touch screen reduces the number
of buttons by changing its configuration for each device
selected. In this way, the touch screen can provide a total of
224 buttons (8 devices x 28 buttons each).
It will turn itself off about 20 minutes after the last use.
