2A2IJ-SAINT0208Tire pressure monitor

Tire pressure sensor user manual No: O‐Sa01E Statement: There is a lithium battery in the sensor. The sensor send the signal by radio signal, the same mechanical size sensor may be used for totally different car. The user must make sure the sensor is suit for your car. 1. Before user installs the sensor, we recommend user read the sensor ID by TPMS diagnostic unit, make sure the sensor is qualified before user put it in the tire.

RF Exposure evaluation FCC ID: 2A2IJ-SAINT0208 1. Applicable Standard According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. KDB447498 v06: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies. 2. Limit FCC: Systems operating under the provisions of FCC 47 CFR section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as mobile device whereby a distance of 0.2m normally can be maintained between the user and the device, and below RF Permissible Exposure limit shall comply with. In accordance with KDB447498D01 for Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneous transmitting antennas incorporated in a host device, based on the calculated/estimated, numerically modeled or measured field strengths or power density, is ≤ 1.0. The MPE ratio of each antenna is determined at the minimum test separation distance required by the operating configurations and exposure conditions of the host device, according to the ratio of field strengths or power density to MPE limit, at the test frequency. Either the maximum peak or spatially averaged results from measurements or numerical simulations may be used to determine the MPE ratios. Spatial averaging does not apply when MPE is estimated using simple calculations based on far-field plane-wave equivalent conditions. The antenna installation and operating requirements for the host device must meet the minimum test separation distances required by all antennas, in both standalone and simultaneous transmission operations, to satisfy compliance. Limits for Maximum Permissible Exposure (MPE)/Controlled Exposure Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density (mW/cm²) Averaging Time (minute) Limits for Occupational/Controlled Exposure 0.3 – 3.0 3.0 – 30 30 – 300 300 – 1500 1500 – 100,000 614 1842/f 61.4 / / 1.63 4.89/f 0.163 / / (100) * (900/f 2 )* 1.0 f/300 5 6 6 6 6 6 Limits for Maximum Permissible Exposure (MPE)/Uncontrolled Exposure Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density (mW/cm²) Averaging Time (minute) Limits for Occupational/Controlled Exposure 0.3 – 3.0 3.0 – 30 30 – 300 300 – 1500 1500 – 100,000 614 824/f 27.5 / / 1.63 2.19/f 0.073 / / (100) * (180/f 2 )* 0.2 f/1500 1.0 30 30 30 30 30 F=frequency in MHz *=Plane-wave equivalent power density 3. MPE Calculation Method FCC： Predication of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 S=PG/4πR² Where: S=power density P=power input to antenna G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna 4. Result 315MHz: EIRP(dBm)= 50.33(dBuV/m)-95.3= -44.97(dBm) 433.92MHz: EIRP(dBm)= 55.49(dBuV/m)-95.3= -39.81(dBm) Mode Output Power Output Power (Turn-up Procedure) Antenna Gain (Numeric) Power Density At 20 cm (mW/cm 2 ) Power Density Limit (mW/cm 2 ) Test Result s (dBm) dBm mW 315MHz -29.85 -29 0.000030.87 0.00000001 0.21 PASS 433.92MHz -23.73 -23 0.000100.87 0.00000082 0.29 PASS 5. Simultaneous transmission MPE Considerations According to KDB447498 :For mobile exposure host platform to qualify for simultaneous transmission MPE test exclusion, all transmitters and antennas in the host must be either evaluated for MPE compliance, by measurement or computational modeling, or qualify for the standalone MPE test exclusion in section 7.1. Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneous transmitting antennas incorporated in a host device, based on the calculated/estimated, numerically modeled or measured field strengths or power density, is ≤ 1.0. This means that: ∑ of MPE ratios ≤ 1.0 315MHz and 433.92MHz Simultaneous evaluation 0.00000001/0.21+0.00000002/0.29 = 0.00000012≤ 1 6. Conclusion This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
