System instruction:

1) WFTPMS adopts the most advanced technology and is one of the most 

    advanced solutions for tire monitoring system in the world

2) WFTPMS consists of wheel-mounted sensor / transmitters inside each tire 

     which measure inner air pressure and temperature and transmit this data 

     to a receiver within the view of the driver. WFTPMS begins working when 

     the receiver is powered on

3) If the pressure or temperature is abnormal, WFTPMS warns. The buzzer 

    alarms and the LCD displays exact value of pressure or temperature of the 

    problem tire. The threshold can be set according to requirements of different 

    vehicles and drivers, and pressure unit and temperature unit can be 

    converted according to drivers in different countries and regions

4) WFTPMS can be applied to cars and light commercial vehicles with cold tire 

    pressure under 6.375bar. Receiver connected to the cigarette lighter socket 

    and transmitters use Lithium batteries with working life no less than 5 years. 



Basic functions:

1) High-pressure warning: warns when tire pressure is too high (overpass 

    the threshold)

2) Low-pressure warning: warns when tire pressure is too low

3) High-temperature warning: warns when tire temperature is too high

4) Low-battery warning: warns when transmitter battery cannot afford full 

    display

5) No-signal warning: warns when sensor is damaged or lost

6) Sudden-change warning: warns when tire pressure changes abruptly

7) Read function: checks the present pressure and temperature condition

8) Set function: sets warning threshold and unit

9) Wheel rotation function: operates when wheels are rotated

10) Initializing function: defaults to factory setting
