PC8-TX-201Run Safe Tire Pressure Warning System

Mod ulation Data (Output)

FCC ID: PC8-TX-201 Description of Operation Clarification In the Description of Operation (previously submitted) it says “At thirty (30) second intervals the sensor will read the pressure and compare it to the pressure stored in memory....” In Part 15.231(a) it says “Periodic transmissions at regular predetermined intervals are not permitted....” The description should be clarified by stating that the device is placed directly on the valve stem of the tire and monitors the pressure internally. It only transmits to the receiver/display if there is a fault. It does not transmit at 30 second intervals. The description also states that this device transmits (an A-OK signal) to the receiver/display at 12 hour intervals. This signal tells the operator that the sensor is still operating correctly. FCC Part 15.231(a) says “...polling or supervision of transmissions to determine system integrity of transmitters used in security or safety applications are allowed.” Since this device monitors a vehicle’s tire pressure, it is used in safety applications, allowing the transmission once every twelve hours. I hope this clarifies the operation of this device and shows that it does meet the operational requirements specified in 15.231(a).

NOTE: The conducted emissions test was not required because the EUT is powered from a DC power source. It does not have a line cord to plug into the A.C. power line. 2.0INTRODUCTION On September 21 & November 13, 2000, a series of radio frequency interference measurements were performed on Transmitter, S/N NA. The tests were performed according to the procedures of FCC as stated in MP-1 “FCC Methods of Measurement for determining Compliance of Radio Control and Security Alarm Devices and Associated Receivers”. Tests were performed by personnel of D.L.S. Electronic Systems, Inc. who are responsible to Donald L. Sweeney, Senior EMC Engineer. 3.0OBJECT The purpose of this series of tests was to determine if the test sample could meet the radio frequency emission requirements of the FCC "Rules and Regulations", Part 15, Subpart C, Sections 15.231 (a-d), 15.207 and 15.205 for Intentional Radiators operating in the bands 40.66 to 40.77 MHz and above 70 MHz Frequency Band with periodic operation. 4.0TEST SET-UP All radiated emission tests were performed at D.L.S. Electronic Systems, Inc. The radiated tests were made with the test item placed on a non-conductive turntable located in the Test Room with the receive antenna placed three meters from the device under test. The equipment under test was set up according to ANSI C63.4-1992, Section 8, (Figures 9c and 9d). EMC Test ServicesReport No. 8640 1250 Peterson Drive, Wheeling, Illinois 60090, USA11/28/00 Page 9 5.0TEST EQUIPMENT (Bandwidths and Detector Function) All preliminary data below 1000 MHz was automatically plotted using the Peak or CISPR Detector Functions. This information was then used to determine the frequencies of maximum emissions. Manual measurements were performed on these frequencies using a peak detector function of the Receiver with the bandwidths specified by the FCC. Above 1000 MHz final data was taken using the Peak Detector. Below 1000 MHz final data was taken using the fixed tuned receiver. Plots were made using the Peak Detector, with manual measurements made on the frequencies of interest, using the Peak, CISPR, and Average Detector Functions of the receiver. When average measurements were made using the fixed tuned receiver, the average was taken of a linear IF signal as specified by FCC and ANSI C63.4-1992. The fundamental frequency was measured using the Average Detector and the CISPR Detector was used for measuring the Harmonics as stated in Section 15.209. From 10 kHz to 30 MHz a bandwidth of 9 kHz was used. From 30 MHz to 1000 MHz a bandwidth of 120 kHz was used and above 1000 MHz, a bandwidth of 1 MHz was used to ensure proper…
