C. USB is flashing on the interface LCD screen
1. This indicates the USB trigger cable is not plugged into your computer
D. It looks like buttons are being held down because the button interface lights are on
1. Check the interface settings first – it is likely that the interface is set for the wrong box
(i.e. 2x2 instead of 1x4 etc)
2. Ask the participant if they are pressing/holding down the buttons
3. Check the actual button box to see if something is pressing against the buttons
E. Interface Menu Issues
1. If you get "lost" in the menu, just scroll down to "back" until you get to the proper menu
