3.14 Touchscreen (Optional)
The touchscreen is connected to the internal USB port. Its function is sim-
ilar to that of a mouse. The only difference is that you put your fingertip
on the screen to move the cursor.
You will need to install the touchscreen driver before it will work. The
touchscreen drivers for various operating systems are stored on the CD-
ROM disc inside the accessory box. The touchscreen manual can also be
found on this disc. Read Chapter 6 of this manual carefully before you
install the driver.
