Thank you for buying our automobile tire pressure monitoringsystem This product can be used for light vehicle with tire pressure under 35Bar For a safe and correct use of it please read this manual first .; , . INTRODUCTION 03 02 FOREWORD Three different inflation condition of tire A. ormal n B. low pressure C. high pressure According to statistics , about 70% of all traffic accidents are caused by tire blowout , while the figure would be higher to 80% . The statistics of SAE shows that there are over 260000 accidents caused by tire fault , and about 75% tire fault is caused by low pressure or leak . NHTSA in US develop a project which require all vehicles with gross weight less than 4500 Kg should be installed TPMS product .It is because long time driving under abnormal tire pressure or temperature that rubbing abrasion of tire become rapid to cause tire blowout . The aim of TPMS is to notice the driver to keep tires in correct condition when driving. Just as the figures showed below , figure B and C result in stress centralization that is makes the tire sho ulde r be a brad ed ra pidly if u nde r lo w p ressu re c ond itio n while the centre part be abraded rapidly if under high pressure. This product belongs to Pressure-Sensor Based TPMS . The sensor is mounted as valve cap to measure the pressure and temperature . The tire is monitored all the time, and our product can send alarm information to driver to tell the emergency of improper pressure or temperature when it is under abnormal condition.The driver can keep the tire in good condition after having this product , thus the tire life can be extended.The driver can avoid increasing the braking distance and making the auto sideslip on wet road with this product.Gas saving is another important benefit to customers if using this product. This product makes you drive safely . If there’s any abnormal, it can send the message immediately including the value of the pressure and temperature , which makes you drive reliably. Our TPMS product uses reliable integrated circuit, according diffusible silicon sensing principle and RF communication principle, which makes the product perform well, easy to install and work stably. This type product is one of the most advanced TPMS products in the world. OPERATION 05 3. The Power Saving Mode:Power Saving Mode: system will be in power saving mode automatically when the receiver hasn’t detected any vibration in 30 minutes.Status of Power Saving mode: The receiver doesn’t do anything except detecting vibration ( no display in screen ; back light off ; the receiver doesn’t receive any data sent from sensors) when it is in Power Saving mode.Resuming to normal operation mode : in case of any vibration detected by the receiver ,the receiver will return to the normal operation mode . 2. Power onWhen the receiver is turned on , the system starts self-checking . The LCD , LED and back light are on . The screen enters into initiate state as picture 1. The self-checking will be finished in three seconds. Picture 1 Picture 2 OPERATION 04 Up Key Enter Key Down Key DC 5V Switch 1. Key introduction Enter Key : confirm the settings. Up Key : set and increase. Down Key : set and decrease. Switch : to turn on /off the receiver. DC 5V : to be connected to the accompanied charger . This product can monitor the pressure and the temperature of each tire.It will warn the driver if any tire is abnormal A Set function to set the standard value of pressure, unit of pressure and temperature, high temperature threshold ; exchange sensors’ position; setup sensors.B) warning function: Low pressure warning, high pressure warning, leakagewarning, high temperature warning, low power of sensor warning, no signalwarning.  : OPERATION 07 Picture 3 Picture 4 06 4 Display interface . Receiver battery : to show current energy of the receiver battery. When the icon is flashing , it means low power for the receiver and the receiver must be charged by the charger in time. charging temperature: 0 45  - OPERATION Low power of sensor warning: the buzzer turns on for 6 beeps and red LED is on ; The icon of the warning tire and the icon of low power are flashing; the buzzer will stop buzzing if any key is pressed. The warning message of each tire will be displayed in turn if more than one tire is under abnormal condition . B) No signal warning: the buzzer turns on for 2 beeps and red LED is on; no pressure and temperature of the tire is displayed, the icon of the warning tire and the icon of “ no signal” are flashing; the buzzer will stop buzzing if any key is pressed. The warning message of each tire will be displayed in turn if more than one tire is under abnormal condition. 5. Value of tire pressure: to show the real-time tire pressure.Value of tire temperature: to show the real-time tire temperature.setup:S-P : to set the standard tire pressure.W-T : to set the tire high temperature threshold.L-C : to set up sensors.E-P : to exchange sensors positions in case of tire rotation. Value of tire pressure Set up Value of tire temperature Warnings Receiver battery 09 Picture 8 OPERATION Picture 7 OPERATION 08 Picture 5 Picture 6 C) Leakage warning: the buzzer turns on for 6 beeps and red LED is on; the icon of the warning tire and the icon of leaking are flashing; the buzzer will stop buzzer if any key is pressed. The warning message of each tire will be displayed in turn if more than one tire is under abnormal condition.

Receiver WTRX003 Circuit Description 1. RF signals transmitted by the antenna to the S1. S1 is a SAW filter, can be useful in screening out 433.92-434.02MHz signal, and then sent data to the U3 TP31371FNG, U3 is a UHF Receiver. It will demodulate the received RF signal data and send it to the MCU. After that data will be transmitted by the MCU to the U1 HT1622, U1 is the LCD Controller. Finally detected data will be shown in LCD display. 2. When receiver received abnormality information, the buzzer turns on and red LED is on: the value of pressure, the icon of the warning tire are shown in display.
