Below is the response from IC regarding ATCB006873 (IC: 7032A-PMBR) application. Basically they are stating that the changes described in your cover letter constitute a Class II permissive change. Basically, I will need a new test report showing the levels that you reported in the cover letter. When that information it provided, I can proceed with listing of this modified equipment on the REL for Canada. Please contact me if you have any questions.

Currently I am reviewing an application for Schrader Electronics Limited in Antrim, Northern Ireland (IC: 2546A-G43MAS - an existing family to a previously certified model). The cover letter attached explains the minor changes being made to this tire pressure monitor transmitter. They are changing the frequency of the crystal oscillator from 9.840625 MHz to 9.837875 MHz in the design. The schematic diagrams, block diagrams and internal photos of the devices are identical to the original one. ATCB approved the original device so I have access to these files. The only differences are the size of the caps on the valve stems. My questions are as follows: 1) Is the change acceptable to IC without requiring a new application for Certification under a different IC number? 2) Is a test report required even though this appears to be a Class I change even though they are adding new model number as an existing family application? 3) If a test report is required, can I use the original test report even though it is older than 1 year?

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.

The Schrader Electronics GM C lamp In Sensor is 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 not ify the system during an RF transmission if the battery performance degrades. • Notify the system if there are abnormal pressure variations (leak) in the tyre.
