Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. The device must be located 20 cm or more from persons. The device must not be co-located with other transmitters. These warnings must be included in the user manual of the final configuration where this device is utilized. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Any modification or use other than specified in this manual will strictly void the certification to operate the device. This device carries FCC modular approval and as such is labeled with FCC ID TIADC310. If this label is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed DC310 module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: TIADC310” or “Contains FCC ID: TIADC310.” Any similar wording that expresses the same meaning may be used. Warning: DC310-OFD radar is supplied in an open frame format with exposed antenna and electronics and thus is a static sensitive device. Please use static precautions when handling. Warranty does not cover damage caused by inadequate ESD procedures and practices. Note: Specifications may change without notice. Note: Not liable for typographical errors or omissions.

FCC ID TIADC310 14570 Page 1 of 1 Request for Modular Approval Regarding requirements of Paragraph 15.212(a)(1) Shielding 15.212(a)(1)(i) The oscillator/transmitter circuitry is housed under a metal shield soldered to the circuit board. Buffered Modulation/Data Input 15.212(a)(1)(ii) No modulation is present. The CW signal emitted by U8 is mixed with its own reflected signal from outside target motion to produce an audio-spectrum mixing product which is connected only to the microcontroller chip U1. Power Regulation 15.212(a)(1)(iii) The RF components are powered by a locally regulated 3.3 V source. Antenna Construction 15.212(a)(1)(iv) The antenna is a permanently attached printed circuit patch antenna with no external connectors. Test Configuration 15.212(a)(1)(v) The device was tested stand-alone with no external shielding. No ferrites were used on the attached cable. There was no coupling to support equipment as the connecting cable measured 15.5 meters to a plastic box. The plastic box provided termination to connect the 12 Volt battery with another 0.5 meters of wire. There was no modification made to the attached power source which is a commonly available lead-acid battery pack. Labeling 15.212(a)(1)(vi) The module is labeled with the FCC ID using a permanently applied printed label as depicted in other supporting documentation. The user manual, page 2, contains instructions for external labeling when the module is enclosed in a final design. Applicable Requirements on Final Configuration 15.212(a)(1)(vii) The user manual includes instructions that explain the requirements of marking and the instructions that need to be conveyed to the final configuration. Compliance to RF Exposure Requirements in Final Configuration 15.212(a)(1)(viii) The user manual includes instructions on the warnings required for the final configuration. ***

Request for Confidentiality Date: April 10 th 2013 Subject: Confidentiality Request for: ______FCC ID TIADC310______ Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, the applicant requests that a part of the subject FCC application be held confidential. Type of Confidentiality Requested Exhibit Short Term Permanent Block Diagrams Short Term External Photos Short Term Permanent* Internal Photos Short Term Permanent Operation Description/Theory of Operation Short Term Permanent Parts List & Placement/BOM Short Term Permanent Tune-Up Procedure Short Term Permanent Schematics Short Term Test Setup Photos Short Term Permanent* User’s Manual *Note: We request that the internal photos be kept confidential because our product is typically installed on poles inside traffic monitoring equipment and not accessible by the general public, but by a technician. The general public therefore does not have access to an internal view of our product. Public disclosure of this information might be harmful to the company and provide unjustified benefits to our competitors. Additionally, we sell either the unit in a completely encapsulated form where you cannot even get to the inside of the unit, or encapsulate the PCB components, so there are no serviceable parts at all, the only option being to replace the whole radar with a new one. Houston Radar LLC has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage we have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of 180 days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify ACB in the event information regarding the product or the product is made available to the public. ACB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705. NOTE for Industry Canada Applications: The applicant understands that until such time that IC distinguishes between Short Term and Permanent Confidentiality, either type of marked exhibit above will simply be marked Confidential when submitted to IC.

14570 TIADC310 Page 1 of 1 1.0 Maximum Permissible Exposure Evaluation The results of power measurement and intended use/proximity are compared against the requirements for safety of RF exposure. 1.2 Criteria Section Reference Date 2.1091, OET Bulletin 65, RSS‐102 July 29, 2013 1.3 Procedure Using measurement of peak power and intended application, determine the permissible exposure level or whether additional exposure tests (SAR) are indicated. Justify conclusion for selected exposure area and separation distance. 1.4 Results Antenna for this device is a printed circuit phased array with unidirectional characteristics. It is operated from inside a plastic enclosure through which the signal must pass. Transmission is continuous as long as power is available; power is typically from a sealed lead-acid battery. The final device is mounted, usually temporarily, to a utility/traffic pole and placed facing passing vehicles to detect motion. Data is recorded by the attached recording system until manually shut down or the battery is drained. A separation distance of 20 cm was selected for a mobile device. Power is determine from the measured field strength at 3 meters and antenna gain applied to determine ERP. The ERP is compared to the referenced table threshold value. For frequency range of 1.5 to 100 GHz, the general population/uncontrolled limit to exposure is 1 mW/cm 2 . Measured Field Strength At Distance Calculated EIRP 120.7 dBμV/m* 3 m 352.5 mW *This is the peak measurement. Field density is determined at 20 cm as: S = EIRP / (4 π 20 2 ) Ref. FCC Bulletin OET-65 Equation (4) S = 352.5 mW / 5026.55 cm 2 S = 0.070 mW/cm 2 The power is below the SAR Exclusion Threshold of 1 mW/ cm 2 , it therefore meets the criteria for exclusion from SAR testing. ***
