Modes of Operation
Rotating Mode
Whilethesensor/transmitterintheRotatingMode,itshallsatisfythefollowingrequirements.The
sensor/transmittershalltransmitaninstantaneousmeasureddata,asdefinedinSection3.1ofthis
document, if a pressure change of 2.0 psi from the last transmission or greater has occurred with respect
to the following conditions. If the pressure change was a decrease of pressure, the sensor/transmitter
shall transmit immediately every time it detects the 2.0-psi or greater pressure changes from the last
transmission.

Stationary Mode
While the sensor/transmitter in the Stationary Mode, it shall satisfy the following requirements. The
sensor/transmitter shall transmit an instantaneous measured data, if a pressure change of 2.0 psi from
the last transmission or greater has occurred with respect to the following conditions. If the pressure
change was a decrease of pressure, the sensor/transmitter shall transmit immediately every time it
detects the 2.0-psi or greater pressure changes from the last transmission.
If the pressure change of 2.0 psi or greater was an increase of pressure, the silent period between the
RPC transmission and the
last transmission shall be 30.0 seconds, and the silent period between the RPC transmission and the next
transmission (Normal scheduled transmission or another RPC transmission) shall also be 30.0 seconds, to
be in compliance of FCC Part 15.231.
Factory Mode
The factory mode is the mode that the sensor shall transmit more often in the factory to assure the
programmability of the sensor ID during the manufacturing process.
Off Mode
This Off Mode is only for production parts sensors that are used for the builds during the production
process and not in the service environment.
LF Initiation
The sensor/transmitter must provide data upon the presence of an LF signal. The sensor must react
(Transmit and provide data) no later than 150.0 ms after the LF data code has been detected at the
sensor. The sensor/transmitter must be sensitive (As sensitivity is defined in Table 1) and able to
detect the LF field.
