Mode
1. Configuration State
  - All sensors should be in the Low Line state.
  - In High Line configuration, sensor transmissions occur every 1 minute (nominal) and pressure is measured every 4 seconds.
2. Normal Delayed Auto State
  - This is High Line specific and is used for all HMC/KMC High Line applications.
  - In this state, the sensor will transmit for approx. 12 minutes before automatically entering storage state.
3. Storage Auto State
  - This state is a Low quiescent current state.
  - In this state;
    1. Ignition off.
    2. The sensor does not measure pressure/temperature/battery level.
    3. The sensor will not transmit, unless requested to do so by the initiate command.
4. Alert State
  - The sensor automatically enters this state if the measured temperature exceeds 110°C and over temperature shutdown is likely.
  - In this state, pressure is measured every 4 seconds and RF data transmitted every 4 seconds.
  - The state lasts for 1 minute if it is pressure triggered.
