Lenk, for Professional Testing (EMI), Inc., being familiar with the FCC rules and test procedures have reviewed the test setup, measured data and this report. I believe them to be true and accurate. The Long Range System T2-500 Transmitter was tested to and found to be in compliance with FCC Part 15 Subpart C for an Intentional Radiator. The highest emissions generated by the above equipment are listed below: Frequency (MHz)Level (dB μV/m)Limit (dBμV/m)Margin (dB) Fundamental467.7580.781.9-1.2 Spurious935.545.046.0-1.0 Occupied Bandwidth Record Only Per 47 CFR 15 - Widest OCBW: 11.8 kHz ______________________________ Jeffrey A. Lenk President This report has been reviewed and accepted by Long Range System. The undersigned is responsible for ensuring that the T2-500 Transmitter will continue to comply with the FCC rules. ______________________________ Certificate of Compliance FCC ID# M74T2500 Professional Testing (EMI), Inc.Page 4 of 15 1.0EUT Description The Equipment Under Test (EUT) is the Long Range System T2-500 Transmitter. The T2-500 Transmitter is used to control the operation of a remote receiver. The T2-500 Transmitter has four pushbuttons which, when pressed, wake the microprocessor from an inactive state. In the sleep state, all functions are powered off including the processor clock. The EUT operates at 467.75 MHz and is designed for compliance with 47 CFR 15.231 of the FCC rules. Specific test requirements for this device include the following: 47 CFR 15.231 Fundamental Transmit Power 47 CFR 15.231 & 15.205Spurious Radiated Power 47 CFR 15.231 & 2.1049Occupied Bandwidth (2.989 used as Procedural Reference) 47 CFR 15.203Antenna Requirement The system tested consisted of the following: Manufacturer & ModelSerial # FCC ID #Description Long Range SystemN/AM74T2500Low Power T2-500 TransmitterTransmitter A separate verification report pursuant to Part 15, Subpart B has been prepared for the Long Range System, T2-500 Transmitter as a Digital Device. 1.1EUT Operation The T2-500 Transmitter was tested with the wireless link active and fully modulated.
