Liepa the Power of Attorney is on file and can be provided when so requested. Re: Certification for Lear RFA-X-05 Receiver Model: RFA-X-05 FCC ID: KOBGR05A IC: 3521A-R05A 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.

The microcontroller will decrypt the message and will send a digital message to the bus communication circuitry; the bus communication circuitry will then send the message at the proper voltage levels over the communication bus to other devices. The power regulation circuitry supplies a 5V regulated voltage to the rest of the circuits on the module. There are 3 oscillator circuits in the design; oscillator circuit 1 is at 10.17825 MHz, oscillator circuit 2 is at 4.19 MHz, and oscillator circuit 3 is at 32.768 kHz.
