MRXPTPMS13Tire Pressure Monitoring Transmitter

The EZ Sensor is manufactured by the grantee (Schrader Electronics) and sold as an OEM product to automobile dealerships and tire installers. Per 47 CFR 2.909, 2.927, 2.931, 2.1033, 15.15(b) etc..., the grantee must ensure the end-user has all applicable / appropriate operating instructions. When end-user instructions are required, as in the case of this product, the grantee must notify the OEM to notify the end user. Schrader Electronics will supply the following user’s manual to the reseller/distributor and require them to provide this information to the end user at the time of installation. EZ Sensor END CONSUMER USER MANUAL The Schrader Electronics EZ Sensor is a configurable sensor designed to be used in a direct measurement TPM (Tire Pressure Monitoring) System. The TPM Sensor is intended to interface to a receiver/decoder that has been designed to accept the TPM sensor protocol. The TPM Sensor is designed to monitor a vehicle's tyre pressure whilst driving or stationary. An electronic unit inside each tyre (referred to as the TPM Sensor or TPM transmitter) mounted to the valve stem, periodically measures actual tyre pressure/temperature. By means of an RF link, this pressure information is transmitted to a receiver/decoder. The incoming radio frequency signals are decoded, and the data used to inform the driver of the tyre pressure information via the vehicles TPM interface. TPM Sensor main functions are: • Regularly measure the tyre pressure. • Monitor if the wheel is moving. • Periodically transmit tyre pressure using an RF link and a specific protocol. • Monitor condition of the battery and notify the system during an RF transmission if the battery performance degrades. • Notify the system if there are abnormal pressure variations (leak) in the tyre. NOTICE: This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry Canada. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. WARNING: Changes or modifications not expressively approved by the party responsible for compliance could void the user's authority to operate the equipment. The term “IC:” before the radio certification number only signifies that Industry Canada technical specifications were met.

Re: Certification for Schrader Transmitter FCC ID: MRXPTPMS13 IC: 2546A-PTPMS13 REQUEST FOR CONFIDENTIALITY Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, Schrader requests that a part of the subject application be held confidential. Schrader 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. Type of Confidentiality Requested Exhibit Short Term Permanent (1) ID Label & Location Short Term Permanent (3) External Photos Short Term Permanent 1 (4) Block Diagram Short Term Permanent (5) Schematics Short Term Permanent (7) Test Setup Photos Short Term Permanent (8) User’s Manual Short Term Permanent 2 (9) Internal Photos Short Term Permanent (10) Parts List & Placement Short Term Permanent (11) RF Exposure Short Term Permanent 3 (12) Description of Operation 1. Block Diagram includes internal oscillator frequency information that the manufacturer considers to be proprietary. 2. DUT is FULLY potted using a non-removable epoxy based material. Removal of potting material causes irreparable damage to internal circuitry. Photograph exhibits outline the half- clam-shell device before and after potting. 3. A portion of the Description of Operation exhibit contains information relating to the operation and programming of this device that the manufacturer considers to be proprietary. Permanent Confidentiality: Schrader requests the exhibits listed above as permanently confidential be permanently withheld from public review. Short-Term Confidentiality (FCC Only): Schrader requests the exhibits selected above as short term confidential be withheld from public view for a period of 45 days from the date of the Grant of Equipment Authorization and prior to marketing.

They are asking that, per Inquiry 751504, I provide a detailed explanation of how the devices are potted, what the potting material is, how its removal destroys the pcb, and leave me with the impression that a PBA may be needed for every application. Please note that the chemical makeup of the potting material may in itself need to remain confidential as it is proprietary in this industry (not may materials can handle 30g's). Please correspond with the reviewer of KDB Inquiry 751504, relay that internal photographs provided without potting are not obtained by "removing" the potting material, but are "pre-potted" photos, and provide both inquiries with a single, consistent, request for more information if needed. Please indicate if additional PBA requests will be required for every like application. I apologize if the tone of this response seems harsh, I do not mean it to be. However, every delay caused by inconsistent responses requires that I call my clients, outline the problem, request additional information, and request their patience. The current climate in the auto industry makes the final request more challenging as of late. ;) JDB Response: You should not need a PBA request for every filing since you may reference this KDB in each subsequent filing for similar device.
