Also this device has a countermeasure function such as the random delay of transmission time so that the RF signal from each tire will not interfere such as due to the simultaneous transmission. The transmitter device also has a Low Frequency (LF) detector. This detector supports Low Frequency (LF) magnetic field communications allowing the changing of measurement/monitoring states of the transmitter by commands sent via the TPM diagnostic and configuration tool. The RF signal operates at 315MHz and uses ASK Bi-phase modulation. 217652-103 transmits 4 RF packets every 1 minute. Description of Operations P/N Consumer’s Mfg.
