2ATCK-TMSS6C4TPMS SENSOR

1 OPERATION MANUAL OF TPMS SENSOR MODEL: TMSS6C4 Thank you for choosing our TPMS. This guide instructs the technician how to properly mount and dismount a Baolong Huf TPMS snap-in sensor. Introduction of TMSS6C4 TMSS6C4 is the transmitting module in TPMS. Its working frequency is 433.92MHz; Receiver Low frequency：125KHz; -15dBm≥transmitting power@3m. supply: Battery; Radio frequency uses the FSK modulation and Machester encoding mode; Antenna type: Monopole antenna, antenna Gain:-3.7dB~-3.4dB; cable loss：3.12dB.The communication mode between WARDKS and receiving module is RF wireless communication. The module detects pressure and temperature inner the tire periodically and sends these information via RF output circuit to the receiving module. One can manually detect data inner tire by LF wake-up tools. Install it on the rim together with cycle valve. PART ONE MOUNTING AND DISMOUNTING OF TRANSMITTER 1. Mounting of Transmitter 1.1 Identify Transmitter Check whether the prepared sensor is the same with the image below. Note: Only plastic or aluminum caps, aluminum valves and nickel plated valve cores can be used when replaced. ①Self-lock Screw ②Electronal Module 2 1.2 Before the transmitter is installed, the rim around the hole must be cleaned with a cloth. 1.3 Remove the Self-lock Screw ① , insert the valve stem through the rim hole from inside. 1.4 Place the Self-lock Screw ① on the valve stem, and tighten with 5 Nm (44 inch pounds) torque. 1.5 Lock the rim on the tyre changer. (If the mounting head of the tyre changer is positioned at 12 o’clock, then the valve should be at the 7 o’clock position.) Apply lubricant on both the tyre bead and rim. Mount the lower tyre bead on the rim. Ensure that the tyre bead does not touch the electronic module during mounting. 1.6 Mount the upper tyre bead the same way. (If the mounting head of the tyre changer is positioned at 12 o’clock, then the valve should be at the 5 o’clock position.) Inflate the tyre to nominal pressure. 1.7 Apply soapsuds on the valve tip. If no leakage is found, put on the valve cap○ 6 . If unsuccessful, try again. Inside the tyre Outside the tyre 3 1.8 Dynamically balance the wheel before it is placed back on the vehicle. 2. Dismounting of Transmitter 2.1 Deflate the tyre and remove the wheel weights from the rim. Push the tyre bead away from the rim. Make sure to always set the bead breaker at least 90 degrees from the valve stem to avoid damaging the electronic module. 2.2 Firmly fix the wheel on the turntable clamps. (If the mounting head of the tyre changer is positioned at 12 o’clock, then the valves stem should be at the 11 o’clock position.) Apply lubricant to both tyre bead and rim, and then remove the upper tyre bead. 2.3 Use the same procedure to dismount the lower tyre bead. (If the mounting head of the tyre changer is at the 12 o’clock position, then the valves stem should also be at the 12 o’clock position.) 2.4 Final inspection: Visually inspect the rim, valve stem and electronic module to ensure no damage has occurred. 4 PART TWO FCC’s Authentication Announcements Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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.
