Re: Certification for Lear FR06U251 Receiver Model: FR06U251 FCC ID: KOBFR06U251 IC: 3521A- FR06U251 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 Lear FR06U251 Receiver Model: FR06U251 FCC ID: KOBFR06U251 IC: 3521A- FR06U251 REQUEST FOR CONFIDENTIALITY Pursuant to 47 CRF 0.459, Lear requests that a part of the subject application be held confidential. This comprises Exhibits (5) Schematics (10) Parts List (Part of Exhibit only) Lear 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 result in 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.
