First you will have to make sure to set the Function Gesture to Screen Capture. To do so, select Home, Settings, General and the first option is Function Gesture. Tap the far-right side of the Function Gesture to expand the options and select Screen Capture. Also, you will need a blank usb thumb drive inserted into the usb port on the back of the unit. Once you have set the Function Gesture and have a usb inserted in the unit, just tap the screen with two fingers (on the sounder screen) and it will save the screen shot onto the usb thumb drive.
Let me know if this helps.
