PressurePro™ Monitors pressure in tires via electronic Sensors that read pressures and transmit a Radio Frequency (RF) signal to a Monitor which can display those pressure readings.  PressurePro™ Sensors read tire pressure 12,343 times each day (once each 7 seconds) and transmit these updated readings to the Monitor.  Some of these transmissions will be interfered with.  Because of the quirks of RF Transmissions and interference, no guarantee of signal reception can be made.  PressurePro™ is not meant to function as a pressure gauge or a low pressure indicator.  PressurePro™ is a tire pressure Monitoring system that displays tire pressures and which, when a signal is received, will signal low pressures.
