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. 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. These devices carry FCC modular approval and as such are labeled with FCC ID TIAPD300 or TIAPD310. 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 module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: TIAPD300” or “Contains FCC ID: TIAPD300.” Any similar wording that expresses the same meaning may be used. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: I) Reorient or relocate the receiving antenna. II) Increase the separation between the equipment and receiver. III) Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. IV) Consult the dealer or an experienced radio/TV technician for help. This equipment complies with FCC and Industry Canada radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance of 20cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter not described under this FCC ID, except in accordance with FCC and Industry Canada multi-transmitter product procedures. Warning: PD300-OFD/PD310-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.

Date (13/11/2014) TUV SUD BABT TCB Octagon House, Segensworth Road, Fareham, Hampshire, PO15 5RL Subject: FCC 15B DoC Attestation Letter We, Houston Radar LLC, hereby declare that the model PD310 will follow the FCC Equipment authorization procedure: Declaration of Conformity to demonstrate compliance for the Part 15 Class B Computer Peripheral portion of the below model below. PD310 _______________________ Vipin Malik CEO Date: November 13 th , 2014

Request for Confidentiality Date: October 24 th 2014 Subject: Confidentiality Request for: ______FCC ID TIAPD310______ 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 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.

16296 Exposure Supplemental Report Page 1 of 1 Rev 01 1.0 Maximum Permissible Exposure Evaluation (Supplements the test report.) 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, FCC OET Bulletin 65, KDB 447498 Section 4.3.1 RSS‐102 2014‐11‐11 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 Calculation This device is operated typically outdoors and facing vehicle traffic lanes. The operating band is 24000-24250 MHz. Power is determined from the measured field strength at 1 meter and used to determine EIRP. The uncontrolled public separation distance is 20 cm. Table 1.4.1 Power Calculation Measured Power Field Strength dBμV/m* At Distance EIRP Power dBm Source Duty Cycle Factor dB Calculated Average Power dBm Calculated EIRP mW 115.1 1 m 10.73 0 10.73 11.8 *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 = 11.8 mW / 5026.55 cm 2 S = 0.00235 mW/cm 2 The calculations have shown that the equipment meets the General Public Exposure Levels described in FCC 47 CFR 1.1310 Guidelines at a 20 cm point of investigation. ***
