March 7, 2007 RE: Siemens Automotive Corporation FCC: M3N5WY783X The following is in response to the comments made on the above referenced application. 1) IC requires 3 items as part of the labeling. While the Certification number is present, model number and Applicant Name as Certified are not found. Please review. Note that your response cites that the model number is clearly shown on the label. Current labeling appears to show a P/N, which begins with 05. None of the current models begin with 05. Please explain. Your response also cites that the applicant name is shown on the PCB. Internal photographs do not support this fact. Please review. The drawing has been modified to show where the part number is placed without the misleading “0” precursor. Also, below is a zoom-in on the laser etched trade name next to the battery clip. 2) Regarding previous comments 2 & 3, please note that the 125 kHz circuitry does not appear passive as it attaches directly to a powered microcontroller. Additionally, it is uncertain if this initiates 125 kHz response or 433 MHz response, which is the purpose of understanding previous comment 3. Please review further. The following datasheet has been provided to detail that the IC operates a passive transponder (operates without battery), as previously stated. Siemens also reiterates that there is no RF response that can be initiated from the Transponder circuit. Philips Semiconductors Preliminary Information Product Profile PCF7941 November 1999 Security Transponder and RISC Controller, STARC lite Features • Compatible with Security Transponder, PCF7936AS. • RISC Programmable Keyless Entry features • 384 Bit EEPROM • 16-Pin SO package Transponder • 64/32 bit mutual authentication calculation unit • 32 bit unique device identification number • 48 bit Secret Key • Fast mutual authentication (39 ms) • EEPROM read/write protection capability • Excellent sensitivity in read and write mode (35 μT) RISC Controller • Advanced 8-bit RISC architecture • 4 Kbyte ROM, 64 Byte RAM • On-chip RC oscillator (< ±10%) • Short instruction execution time (as fast as 1 μs) • 11 I/O ports, general purpose • Code hopping based on transponder calculation unit • Code hopping synchronization via transponder • Clock input to serve as external data rate reference • Programmable battery low detection • Low power consumption (300 μA, PD 300 nA) • Single battery cell operation (2.1V to 5.5V) • Device supply can be derived from LF Field General Description The PCF7941 is a single chip high performance Security Transponder and Keyless Entry controller, ideally suited for vehicle immobilizer applications that incorporate keyless entry functions. The transponder circuitry is compatible with the Security Transponder PCF7936AS, for use in mixed systems that employ a STARC and a standard Security Transponder, PCF7936AS, at the same time. The Transponder circuitry meets the security and performance requirements of modern car immobilizer applications. Excellent device sensitivity and short authentication time ensure outstanding system performance. The Transponder circuitry does not require any battery supply and full operation is granted in a Keyless Entry battery low condition. The RISC Controller circuitry is powered by an advanced low power 8-Bit RISC. The device features 11 I/O ports including up to four wake-up inputs for command button sensing. Code hopping generation may employ the transponder Calculation Unit, while telegram transmission characteristics are controlled by the RISC. If the same security algorithm is applied for the Transponder and the Code Hopping function, separate Secret Keys are provided to ensure independent code characteristics. Contactless code hopping synchronization may be accomplished via the conatctless interface. The system timing is derived from a low tolerant on-chip RC- Oscillator. If desired, an external data rate reference clock may be applied for use with common PLL transmitter devices.

This comprises Exhibits (5) Schematics (10) Parts List (Part of Exhibit only) Siemens 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.

March 3, 2007 RE: Siemens Automotive Corporation FCC: M3N5WY783X The following is in response to the comments made on the above referenced application. 1) IC requires 3 items as part of the labeling. While the Certification number is present, model number and Applicant Name as Certified are not found. Please review. The location of the model/part number is clearly indicated on the label. The applicant name is marked on the PCB, visible when the battery is replaced. This meets IC’s requirements. 2) Given the operational description, it is uncertain if this device is also subject to transmission at 125 kHz. Please explain. The DUT contains a passive 125 kHz transponder coil, and is not capable of active transmission at 125 kHz. 3) In transponder mode, does the device automatically activate. Please explain what happens if the device stays within range of the 125 kHz transmissions for a long period of time. Does it start to transmit? How many times? How is it compliant to automatic transmissions requirements? If applicable, please show compliance to the 5 second requirement for automatic transmission as well. The transponder portion of the device cannot initiate an RF transmission. 4) Please explain if the device was investigated both with the key extended and closed. We have seen devices where the worse case for the fundamental may be one condition, while for the spurious emissions may be worse under a different condition. Please confirm if the key condition was investigated for both the fundamental and spurious emissions and that the worse case for both the fundamental and spurious was the same condition. The key you are referring to does not “extend,” but may be removed by the user for use separate from the device. Emissions were measured with the key in place and removed, and it was determined that the emissions were worse with the key in place (as tested). 5) Please provide a REL Listing Letter for IC. Our apologies, letters have been included with the application forms.

FOBIK Label Information

General Description The FOBIK is a stand-alone handheld device which contains no I/O circuitry and operates as a transmitter (RF) and transponder (LF). In transmitter mode, the circuit is powered by a 3V lithium CR2032 battery and transmits when one of the buttons is pressed; the communication occurs either at 433.92 MHz. There are up to seven buttons on the key, which are used for RKE lock, unlock, trunk or liftgate, left power sliding door, right power sliding door, panic, and remote start. In transponder mode, the circuit is powered by inductive coupling through the magnetic field produced by the base station (WIN module) and communicates at 125 KHz. Technical Data Carrier Frequency: 433.92MHz +/- 0.75 kHz Modulation Type: ASK Method of Generation: Saw Based Colpitts Power Supply: CR 2032 3V Lithium battery

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 Siemens FOBIK transmitter. This device is subject to the Rules and Regulations as a Transmitter. In testing completed on February 2, 2007, the device tested in the worst case met the allowed FCC specifications for radiated emissions by 1.3 dB (see p. 6). Besides harmonics, there were no other significant spurious emissions found. The conducted emission tests do not apply, since the device is powered from a 3 VDC battery. University of Michigan Radiation Laboratory FCC Part 15, IC RSS-210/Gen - Test Report No. 415031-349 Page 2 of 10 1. Introduction Siemens FOBIK transmitters were tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989 as subsequently amended, 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 Area Tes Site are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref.
