Re: Certification for Martec Access HL-1001 Receiver Model: HL-1001 FCC ID: JCQ-955 CANADA: to be provided by IC POWER OF ATTORNEY A letter granting Valdis V. Liepa the Power of Attorney is on file and can be provided when so requested. Re: Certification for Martec Access HL-1001 Receiver Model: HL-1001 FCC ID: JCQ-955 CANADA: to be provided by IC REQUEST FOR CONFIDENTIALITY Pursuant to 47 CRF 0.459, Martec Access Products, Inc. requests that a part of the subject application be held confidential. This comprises Exhibits (5) Schematics (10) Parts List (Part of Exhibit only) Martec Access Products, Inc. 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 they have achieved by developing this product. Not protecting the details of the design will definitely result in a financial hardship. If there are any questions regarding this request, please contact me at the above address or call 734-483-4211, fax 734-647-2106 or e-mail [email protected]. Sincerely, Valdis V. Liepa Research Scientist University of Michigan September 30, 2001 Re: Certification for Martec Access HL-1001 Receiver Model: HL-1001 FCC ID: JCQ-955 CANADA: to be provided by IC STATEMENT OF MODIFICATIONS There were no modifications made to the DUT by this test laboratory. (Also see Section 3.1 of the attached Test Report). _____________________ Valdis V.

October 30, 2001 ATCB Inc. 6731 Whittier Ave McLean, WA 22101 RE: Martec Access Products, Inc. FCC ID: JCQ-955 Dear Mr. Johnson, The following is in response to your request for further information on our submittal for the JCQ-955. 1) The Kg factor used in section 5.3 of the test report includes both cable loss and amplifier gain. At the beginning of each test cycle, the cable and amplifier are calibrated together, resulting in a single Kg factor. 2) The emissions in the 3-m pre-scan, as seen in Figure 5.1 do show broadband squelching oscillator emissions. The statement in Section 5.1 that “only the LO and its harmonics were evident” should not have used the word “LO”, but rather “regenerative oscillator emissions”. 3) A picture of the Conducted Emissions testing has been uploaded under “Correspondence” to the ATCB Website. 4) The DUT is a receiver only and will be marketed as such by Martec Access Products, Inc. There is no specific transmitter it will be intended to work with, and listing a possible competitor’s product is not an option. It is considered a “replacement” garage door opener receiver. If there is anything else we can help with, please let us know. Sincerely, Valdis V Liepa.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 October 27, 2001 RE: Martec Access Products, Inc. FCC ID: JCQ-955 After a review of the submitted information, I have a few comments on the above referenced Application. 1) The information regarding your K G Factor used in calculating the field strength given in section 5.3 of the test report is ambiguous. While the amplifier gain is subtracted during the calculation, the Cable loss should be added. Please explain how the preamplifier gain includes the cable loss. 2) Information given in the test report within Section 5.1 of the test report (regarding the prescan) states that only the LO and its harmonics were seen from the DUT. However, plots provided in Figure 5.1 show broad band emissions from about 300 MHz up to 700 MHz with the EUT powered on. Broad-band emissions seen in the 3-m prescan data can be typical for certain types of super- regenerative receivers. Please help clarify this discrepancy. 3) Please provided test configuration photographs for conducted emissions. 4) The DUT is a receiver only. Please update the 731 section 7(b) & 8 with appropriate information regarding a typical transmitter that the DUT will work with. 5) FYI. The information presented on the 731 in regards to the applicants contact information does not match the information on record at the FCC. This will not affect processing of this application, however I have enclosed a separate attachment that explains how the applicant may go forth changing this if they wish. Timothy R. Johnson Examining Engineer mailto: [email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued.
