It's not the output of the device that poses a threat, but the alligator clip wire that attaches directly to the input of the device. If the line cord plug is not polarized, or the wall outlet is miswired, the alligator clip wire can be at the same potential as the hot side of house wiring--120 volts AC. If you touch the alligator clip under these conditions, a current may pass through you to ground. That's not good!

After sitting and thinking about this for a while I finally realized what your concern is. If the plug is reversed incorrectly the lead with the alligator clip will become hot possibly causing a bad shock if touched wrong when grounded whether the unit is on or not because it would be like grabbing the bare wire. Finally I get it .

Later tonight I will plug it in and measure the output from the alligator clip and the screen with the plug plugged in both ways using my volt meter and mark my plug so I know how to plug it in correctly and report my findings. Sorry for being so dense, I guess I've been lucky so far.
