NVLAP ACCREDITED NARTE Certified Engineer Professional Engineer ELITE Electronic Engineering May 15, 2002 TCB Services 1516 Centre Circle Downers Grove, IL 60515-1082 Re: Application for Certification of Johnson Controls Transmitter under 47CFR 15.231. FCC ID: CB2W211HL3 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 CB2W211HL3 This model, a part of their Homelink® III series, is capable of learning the current garage door transmit frequencies from 288MHz through 420MHz except in the forbidden frequency regions. The complete List of the Exhibits in this submittal package appears on Page 2 of this cover letter. 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. Pursuant to 47CRF 0.459, Johnson Controls Interiors requests that these listed exhibits be held confidential. Circuit Block Diagrams page 2 of Exhibit B Theory/Description of Operation, page 3 of Exhibit B Schematics page 5 of Exhibit B 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.
