Re: Certification for Caterpillar 218-0404-01 Transmitter Model: 218-0404-01 FCC ID: PQMTRM IC: 4071A-TRM REQUEST FOR CONFIDENTIALITY Pursuant to 47 CRF 0.459, Caterpillar requests that a part of the subject application be held confidential. This comprises Exhibits (5) Schematics (10) Parts List (Part of Exhibit only) Caterpillar 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.
