Cover Letter(s)

November 22, 2005 RE: Siemens Automotive Corporation FCC ID: M3N5WY7700 After a review of the submitted information, I have a few comments on the above referenced Application. 1) The FCC ID on the label shows a dash, while the 731 form does not. What is the correct ID? Please confirm and correct all necessary exhibits. Our apologies, the exhibits have been corrected to include the dash. 2) It is uncertain of the actual positioning use of this device. Was is positioned properly on the table, or should it have been positioned with the key upward, or possibly examined in 3 axis? Please review and comment as necessary. As discussed in the test report, section 5.1, emissions were measured for all orientations of the DUT and the test antenna. Please note we have pointed this out many times in the past. 3) Compliance with 15.209(c) can not be assured given results reported. Harmonic at 375 kHz is > Fundamental. As demonstrated in Figure 6.2 in the test report, the emissions from the harmonics are significantly lower than that of the fundamental emission. Please also note that the DUT emissions in general are more than 80 dB below the limit. 4) Please comment on if the 99% bandwidth was measured using IC techniques as specified in the attachment previously provided? Additionally, it does not appear that the measurements meet with the requirements of using RBW > 1%, VBW > 3*RBW and NO Video Averaging? RSS-GEN, section 4.4.1, issue 1. Please correct the IC form as necessary. The bandwidth was measured appropriately. No video averaging was used and the RBW is > 1% of the span. As per the VBW, we have double checked the emission measurement and found no variation in the 20 dB (99%) bandwidth, thus no corrections are necessary. 5) From the new issue of RSS-102, an attestation should be provided for all devices. Please see updated form attached. The attestation has been included in the application forms.

Operational Description

Description of Operation : The Nissan Fob Reader is an immobilization device which allows the operator of the vehicle to start the car by pushing a button once the identity of the fob has been authenticated by the reader. The authentication process is initiated once the fob is inserted into the reader by a mechanical switch which powers up the reader by the car's battery. The antenna drivers of the reader IC output a 125 KHz sine wave at approximately 100 Vpp; this frequency is created by a 4MHz oscillator which is connected to the IC and subsequently divided down to 125 KHz. The fob reader communicates to the fob by BPLM (binary pulse length modulation); the fob communicates back to the reader through ASK modulation by simply attenuating the reader signal through a current limiter. At each communication phase the data is sent via a serial interface to a separate electronic control module which determines the authenticity of the information the fob is providing. Upon successful verification of the fob's ID, the ECU allows the vehicle to be started.

Brunett Report approved by: _____________________ Valdis V. Liepa Research Scientist Summary Tests for compliance with FCC Regulations, Part 15, Subpart C, and for compliance with Industry Canada RSS-210/Gen, were performed on Siemens VDO Automotive transmitter, models A2C53117564, A2C53123872, and A2C53162853. This device is subject to Rules and Regulations as a transmitter. In testing completed October 7, 2005, the device tested in the worst case met the allowed specifications for transmitter radiated emissions by 31.1 dB (see p. 7); digital emissions, Class B, were met by more than 20 dB. The conducted emissions tests do not apply, since the device is powered from a 12 VDC system.

Introduction Siemens models A2C53117564, A2C53123872, A2C53162853 were tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989, and with Industry Canada RSS- 210/Gen, Issue 6, September 2005. The tests were performed at the University of Michigan Radiation Laboratory Willow Run Test Range following the procedures described in ANSI C63.4-2003 "Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz". The Site description and attenuation characteristics of the Open Site facility are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref.
