S8.21 is the transmitting module in TPMS.

working frequency ：433.92MHz;

Receiver Low frequency：125KHz;

transmitting power: ≥-60dBm @3m

supply: Battery;

Radio frequency encoding mode : FSK modulation and Manchester encoding mode;

Antenna type: Monopole antenna；

Antenna Gain: -25dBi;

The communication mode between 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

1.3 Once the tire has been positioned and “blocked,” carefully place the sensor on the rim base. (Figure B) 1.4 When positioning the sensor watch for pinch points between the magnets and the rim base surface. Valor uses extremely powerful magnets to hold the sensor to the rim. (Figure C) 1.5 If you are unable to position the sensor in the center of the rim, use a non-metal extension to push he sensor further toward the center.

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.
