Even if the driver has accelerated the speed up to 150 km (93 mile), this system is still able to detect the tire pressure condition consistently. Essentially, the warning mode feature will mostly be relied upon as the Front Tire and Rear Tire pressure values have dropped down to 30+/- 2 psi and 32 +/ - 2 psi, respectively. There will be two different kinds of warning indications on the display panel. One of the warning indications is the visual warning signal – a red flash light, and the other one is an audio warning to inform the driver of the tire condition relating to the tire pressure such that it is danger to continue operating the vehicle. The Transmitter will immediately send the audio signal to the Receiver Module when the system has found out the abnormal condition. At the same time, a Red Flash Light signal on the Receiver Module panel will be on to confirm the driver regarding the tire condition. The visual warning indication will be off only when the driver has taken a further action or pressed the reset button to clear the stored memory. 3 Display Panel Aspirit Enterprises, Inc.
