Functions: 

1) Continually monitors tire pressure and temperature conditions, and warns 

    the driver to take precautions so as to prevent dangerous accidents

2) High-pressure warning: warn when tire pressure is too high (overpass the 

    threshold)

3) Low-pressure warning: warn when tire pressure is too low

4) High-temperature Warning: warn when tire temperature is too high

5) Low-battery warning: warn when transmitter battery cannot afford full display

6) No-signal warning: warn when sensor is damaged or lost

7) Sudden-change warning: warn when tire pressure changes abruptly

8) Read function: check the present pressure and temperature condition

9) Set function: set warning threshold and unit

10) Wheel rotation function: operate when wheels are rotated

11) Initializing function: default to factory setting
