Copied from a great guy on FB....... Lock ZNA by clicking fire button 5 times. Press and hold fire button press and hold right button at the same time, keep holding until left or right mode shows up, keep holding until the right mode comes up. Repeat the same thing but with the left button for stealth. If you want right mode, but are in left mode, left mode will show up first, keep holding until right mode shows up then release the buttons.
