How does the Valve Caps work?

First time you put the cap onto the valve stem it take a sample of the tire pressure and saves it into a reference chamber. If the tire pressure drops 4 or 8psi from the original pressure the cap will start flashing. It is importaint to know that we are using air pressure as a reference which means our reference pressure automaticilly follows the temperature and pressure of the tires.

* extreme heat and cold will shorten the battery life and performance. The batteries are Alkaline Magnese button cell. Batteries are totally intergrated into the design and cannot be changed. For more information about batteries : http://www.duracell.com/oem/Pdf/others/ATB-full.pdf

** a pressure peak can occure for exaple when the tire hits a hole in the road or is driven over the edge of the curb
