ANNEX............................................................................................. 16 3 Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. 4 1. INTRODUCTION OF TPMS TPMS is the shortened form of tyre pressure monitoring system. TPMS is the active safety system of vehicle. It is used for real-time monitoring tyre pressure and tyre temperature and transmitting the information of tyre to driver timely and accurately. TPMS can reduce the risk of tyre blowing and damaging resulted from low pressure, high pressure, and high temperature and leaking. Thus protect effectively the life and property of drivers and passengers. TPMS display can be installed directly in air-conditioning vent in cab. It can be also installed in other suitable position through mushroom stick. The four sensors are installed inside tyre respectively. When the vehicle starts and its speed is higher than 20km/h, the sensors installed inside tyre can real time collect the tyre pressure, tyre temperature and so on. Then the information is transmitted by radio to TPMS display. TPMS display displays corresponding information after it receives the wireless signal and alarms when the tyre is abnormal. 2.

TPMS PRODUCT SPECIFICATION SET T/P NEXT Indication Light Power Supply Interface Fig 1 TPMS Display Fig 2 TPMS Sensor Indicator light introduction ① Green：State indication that shows the system is normal and has no alarm information； ② Red：Alarm indication that shows alarm information exists in the system. 6 Key introduction: ① “SET” is the key used for setting. The tyre interchange can be done with this key. The particular operation is as the following paragraph 6: Tyre Interchange Setting Specification. ② “T/P” is the key used for switching the display value of temperature and pressure. Through pressing this key, the value of tyre temperature and tyre pressure on the display can be switched. The tyre ID can be shown on the display after that “T/P” is pressed for 4s. Then press “NEXT”, we can inquire the ID of different tyre. The display of tyre ID can exit through pressing “SET”. ③ “NEXT” is the key that after you press the key for 4s, TPMS comes into matching mode. In this mode, the sensors can be changed by users. Press “NEXT” again, the matching mode can exit. Warm Reminders： When install the TPMS display, don’t install it above air-bag without fail for fear of additional injury to drivers and passengers when the air-bag opens under emergency conditions. If you need to change the sensors, please go to designated 4S shop or vehicle repair garage to do the matching using special tool by career man. If your hub is steel and you need to change the tyre, please change tyre together with valve of tyre pressure sensor. All the figures in the introduction are only the sketch map. Please refer…
