Box 358315 Pittsburgh, PA 15251-5315 Attention: Authorization & Evaluation Division Re: Application for Certification of Johnson Controls Transmitter under 47CFR 15.231. FCC ID: CB2VWHL3 Gentlemen: On behalf of the applicant, Johnson Controls Interiors, LLC, please find attached the submittal materials for certification of the JCI Universal Garage Door Opener, Model CB2VWHL3 This generation of their Homelink® series is capable of learning the current garage door transmit frequencies from 288MHz through 420MHz with pulse modulation, using duty cycles from 30 through 80 percent. Pursuant to 47CRF 0.459, Johnson Controls Interiors requests that these listed exhibits be held confidential. Exhibit G Theory/Description of Operation, Exhibit H: Circuit Block Diagrams Exhibit I: Schematics Exhibit J: Bill of Material, Parts List Johnson Controls Interiors has invested considerable resources into developing this Homelink® series. Having the listed exhibits available to ‘competition’ would negate the advantage achieved in developing this product. Since their Homelink® series transmitters will be a major product line for Johnson Controls Interiors, not protecting the details of the design will result in a financial hardship for the company. The complete List of the Exhibits in this submittal package appears on Page 2 of this cover letter. Your prompt consideration of this application for product certification will be greatly appreciated. Should you have any questions regarding the content of this report, kindly contact me.
