Technical Information Siemens VDO Limphome Module GM Easy Key Active Antenna General Product Information Design Location: Siemens VDO Automotive 4685 Investment Drive Troy, MI 48098 Manufactured Location: Siemens VDO S.A. de C.V. Camino a la Tijera # 3 Km 3.5 Carretera Guadalajara-Morelia C.P. 45640 Mpio. Tlajomulco de Zúñiga, Jalisco Mexico Device ID: GM Easy Key Active Antenna ID: 5WY7155 FCC ID: M3N-65981421 IC: 267F-65981421 General Description The Easy Key Active Antenna is a self contained LF transceiver. The module contains I/O for 12V power, ground, data, and data clock signal. Internally, the device contains a 5V regulator, data I/O circuitry, a PCB trace antenna, and a micro with integrated LF drivers. The device operates using a 4MHz crystal which is divided down to 125 KHz for LF communication. The Active Antenna communicates with a transponder through absorption modulation. The Active Antenna transmits data through an ASK modulated 125 KHz field. The transponder communicates back to the Active Antenna by dampening the field. Power Supply The Active Antenna is powered by an external control module. An onboard regulator supplies 5V to the LF Driver and Logic circuits. This regulator also provides over current, over voltage, and over heating protection. Technical Data Carrier Frequency: 125kHz +/- 2kHz Output Power: ω -33dBuV/m @ 300m Modulation Type: ASK Method of Generation: Microcontroller Number of Channels: 1 Power Supply: Vehicle battery (through ECU) Transmission Range: <25mm

Liepa 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, were performed on Siemens VDO transmitter, model 5WY7155. This device is subject to Rules and Regulations as a transmitter. In testing completed October 28, 2003, the device tested in the worst case met the allowed specifications for transmitter radiated emissions by 23.6 dB (see p. 7); digital emissions, Class B, were met by at least 20 dB. The conducted emissions tests do not apply, since the device is powered from a 12 VDC system. 2 1. Introduction Siemens model 5WY7155 was tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989, and with Industry Canada RSS-210, Issue 5, November, 2001. The tests were performed at the University of Michigan Radiation Laboratory Willow Run Test Range following the procedures described in ANSI C63.4-1992 "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. No: IC 2057). 2. Test Procedures and Equipment Used The pertinent test equipment commonly used in our facility for measurements is listed in Table 2.1 below.
