Manufacturer: Schrader Electronics IC: 2546A-NG33MA4S Apparatus: 40700 1AA0A Dear Sir/Madam It has come to our attention that Schrader has made a mistake in the Canadian RF approval labelling of the products outlined above. We have used “CAN:” from the old requirement instead of “IC” as outlined by the latest RSS specifications. We currently have our Canadian approval number moulded into the enclosure and to change the tooling but be a very significant cost to Schrader. Schrader will make the proper modification to the design when the tooling is next revised. I would appreciate if you could consider our mistake and allow us to continue sale with the products as outlined above. Regards ___________________________ Adrian Condon Schrader Electronics

The rest of this section is brief explanation of the function of the individual modes. NB: In all modes an LF signal will cause a move a transition to “TRANSPONDER INPUT ACTIVE”. 3.2 STATIONARY Mode In normal operation and while the vehicle is not moving the TPMS Sensor will be in STATIONARY mode. In this mode sample and transmission rates are described below. Nissan Part Pressure Sample Rate (seconds) Roll Sample Rate (seconds) Normal Tx Rate (minutes) Re-measure Tx’s (enabled) 40700-1AA0A 30 10 - Yes Table 1: Stationary Mode STATIONARY mode is exited when the vehicle begins to move and roll switch input is verified by the ASIC. 3.3 DRIVE Mode DRIVE mode is the mode the TPM sensor goes to when the vehicle starts moving and motion is detected by the sensor. The activation point of the sensor is dependent on the rotational speed of the wheel and therefore varies depending on wheel and tyre configuration used. As a guideline, the wake-up speed of sensor equates to a road speed of approximately between 3 and 25KPH (2 and 16MPH). DRIVE mode is designed to increase the sample and transmission rate while the vehicle is moving. On entry to DRIVE mode the TPM sensor will sample pressure and do a normal RF transmission with a WAKE function code (see Error! Reference source not found.). After the WAKE transmission the TPM sensor will transmit NORMAL function code data frames with the following sample and transmission rates: Nissan Part Pressure Sample Rate (seconds) Roll Sample Rate (seconds) Normal Tx Rate (seconds) Re-measure Tx’s (enabled) 40700-1AA0A 5 5 60 Yes Table 2: Drive Mode When vehicle speed has dropped below minimum vehicle speed threshold, the transmitter will remain in DRIVE mode for a period of approximately 30 seconds, known as the ‘Service Period’. After the Service Period time has elapsed the TPM sensor will exit to STATIONARY Mode. 3.4 FACTORY Mode (A special case of DRIVE Mode) A special case of DRIVE mode called FACTORY mode is available on the Nissan Gen3 sensor. The difference is an increase in the frequency of transmissions from about 60 seconds, to about 30 seconds.

Description of operation: The TPM sensor / transmitter is a self-contained unit in which there are no electrical connections into or out of the device. The unit monitors and transmits tire cavity pressure and Temperature using an RF signal to a receiver unit. Each TPM sensor contains a unique ID code in its transmission data that a receiver can use to identify tire position or illuminate a warning lamp that identifies that one or more tires has a pressure out of range event.

Liepa Report approved by: _____________________ Valdis V. Liepa Test Report Prepared by: Joseph D. Brunett Research Scientist Summary Tests for compliance with FCC Regulations Part 15, Subpart C, and Industry Canada RSS-210/GEN, were performed on Schrader model/PN(s) 40700 1AA0A. This device is subject to the Rules and Regulations as a Transmitter. In testing completed on February 26, 2008, the device tested in the worst case met the allowed FCC specifications for radiated emissions by 5.5 dB (see p. 6). Besides harmonics, there were no other significant spurious emissions found; emissions from digital circuitry were negligible. The conducted emission tests do not apply, since the device is powered from a 3 VDC battery.

Configuration and Identification of Device Under Test (DUT) 3.1 Design and Identification of the Device The DUT was designed and manufactured by Schrader Electronics Limited, 11 Technology Park, Belfast Road, Antrim BT41 1QS, Northern Ireland. It is identified as: Schrader TPMS Transmitter Model/PN(s): 40700 1AA0A FCC ID: MRXNG33MA4S IC: 2546A-NG33MA4S 3.2 Variants There is only a single variant of this device. 3.3 Modes of Operation The DUT periodically transmits tire pressure data. The device is also capable of being automatically actuated (via LF interrogation) either by in-vehicle LF initiators or by trained personnel during servicing.
