Step 1
Remove the silicon cap (the cap distorts the colors of the light). Hold down the button on the top of your Alice gauge. After about 6 seconds you will see a cyan (light blue) color. Keep holding. After 12-15 seconds the light will turn bright green. This is the color that you want. (Not everyone can see the change in color, which is why we recommend holding it down for 15 seconds). Release the button. The light should flash red, then blink blue, which means your gauge is now in setup mode.
