Note: Before you begin, turn off and unplug your Flex terminal from the outlet.

 

  1. Gently flip and place your Flex Terminal so that the display faces down and you have easy access to the thumb screws on the back. Unscrew the two thumb screws and lift up to remove the back plate.
  2. Next, unplug the green (GFD) and blue (HDMI) cables and remove the cable from the terminal by guiding it back through the stand. Note that there may not be any cables plugged in. If nothing is plugged into the green and blue ports, then move on to Step #3.
