I got an air zenith digital 220psi gauge for my onboard air system a while back and it has this irritating feature of blinking when the pressure drops below 110psi. I don't always need over 110psi, so when your riding around it just blinks at you constantly. I tried tinting it with nightshades, but to no avail it is still an irritant

Anyone have any ideas how I could disable this one function of the gauge system? I have had no luck searching all types of forums, and I don't know of many people with air zenith stuff. I don't want to just start hacking wires, and i have had no luck finding a schematic of the system to even start a search.
