Use a “split washer” is used to ensure the mounting screw remains tight under vibration. Direction Pointing: The DR-1500 is directional in nature. It rejects traffic moving away from it and only measures oncoming traffic. If the optional stats analyzer feature is purchased with the unit, stats will only be collected for incoming traffic. This allows you to position the unit in a median without worry of picking up traffic on the outgoing lane For optimal performance, keep in mind the following: 9 Radar should be mounted with the circuit board horizontal to the road. 9 Radar should be pointed into the direction of the oncoming traffic. 9 Radar should be placed along the size of the road to minimize the angle of the oncoming traffic to the radar. o If radar cannot be placed right along the side of the road, it should be pointed at least 200-300 feet up the road into oncoming traffic. 9 The radar may pickup rotating fans. Avoid pointing it at fans or compressors. 9 Radar should be mounted at least 3+ feet high from the road for optimal performance. Hookup: Power Input : The DR-1500 radar can be powered from a nominal 12V DC battery and features industry leading operation…

On behalf of Houston Radar, LLC, Professional Testing (EMI), Inc. is seeking a modular approval for the DR1500 Doppler Radar. Requirements listed in FCC Public Notice DA 00-1407 are addressed below. 1) The device has a RF shield installed. The RF portion of the device is a Gunn Oscillator which is enclosed in a solid metal case. Please refer to the internal photographs. 2) The external data inputs are routed to a microcontroller. All of the data inputs are buffered. 3) The RF portion of the device contains internal power supply regulation. 4) The antenna requirement is addressed in the test report. 5) The module was tested in a stand alone configuration. It is intended to be used as a Serial device. While testing the unit was powered using an external 12 Volt Battery 6) A sticker is affixed to the back side of the EUT. The manual contains the explicit directions to label the exterior of the the device into which the EUT is integrated with “Contains FCC ID:TIADR1500”. 7) The Users Manual explains that any modifications may strictly void the certification and a separate approval must be obtained. 8) The device is very low power. The maximum rated power of the device is 5mW. The device is not intended to be mounted within 20 cm of a human. The device is therefore exempt from SAR evaluation.

1601 FM 1460, Suite B Round Rock, TX 78664 e-mail: [email protected] (512)244-3371 Fax: (512)244-1846 March 24, 2008 FCC ID: TIADR1500 In response to your comments regarding the application for certification of the device referenced above please find our response below: 1.) Users Manual must have Pt. 15.21 statement. The Users Manual has been updated to reflect the Pt. 15.21 statement. 2.) Modular Approvals need to have power line conducted test included as there are no guarantees that the end user will not connect to power grid. This can be accomplished using any store bought power converter. Conducted Emissions testing has been completed. The test report and test setup photos have been updated. 3.) Question 7 in modular approval letter is not in the user manual. Please revise user manual. The Users Manual has been updated to address Question 7.

Royer, for Professional Testing (EMI), Inc., being familiar with the FCC and IC rules and test procedures have reviewed the test setup, measured data and this report. I believe them to be true and accurate. The Houston Radar, LLC., DR1500 Doppler Radar 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 (dBμV/m) Limit (dBμV/m) Margin (dB) Fundamental 24142 120.7 137.5 -16.8 Spurious 7246 50.1 54 -3.9 Occupied Bandwidth 350 (kHz) Jason Anderson Director of Testing Services This report has been reviewed and accepted by Houston Radar, LLC.. The undersigned is responsible for ensuring that Houston Radar, LLC, DR1500 Doppler Radar will continue to comply with the FCC and IC rules. Certificate Of Compliance Professional Testing (EMI), Inc. Project 08198-10 Page 4 of 19 1.0 EUT Description The DR-1500 is a Doppler speed radar is powered by 12V DC nominal voltage. The microwave Gunn oscillator in the transceiver generates a 24.1 GHz signal and sends it continuously out of the patch antenna at the target. The signal also "illuminates" internal (to the microwave transceiver) mixer diodes that act as a receiver mixer. The transmitted radar waves are reflected off the moving target, change the reflected microwave frequency per the well-known "Doppler principle" and are received by the same transmitting horn antenna and mixed in the receiving mixer diodes with the local oscillator. The difference in the transmitted/received frequencies is produced as a low frequency (audio frequency range) out of the mixer diode and into the preamp. The system tested consisted of the following: Manufacturer & Model FCC Number Description Houston Radar, LLC., DR1500 TIADR1500 Doppler Radar 1.1 Applicable Documents Guidelines FCC Rule Parts Part 15 Transmitter Characteristics 15.245 Spurious Radiated Power 15.205, 15.209, 15.245 Antenna Requirement 15.203 Spurious Conducted Emissions 15.207 1.2 EUT Operation The EUT was operated in continuous transmit mode at max power to measure fundamental, …
