EnTire Solutions, LLC 24175 Research Drive Farmington Hills, Mi 48335 FR – Letterhead 03/06 RE: Certification for EnTire Solutions, LLC TPM MY05 Lowline Receiver Model #: 218695-102 FCC ID: T7B-4R Canada IC: 6484A-4R GENERAL DESCRIPTION The TPM Lowline receiver is used to monitor RF transmissions from the TPM wheel sensors. The TPM wheel speed sensors transmit information continuously to the receiver on a periodic basis. The transmissions contain information on the pressure and temperature of each of the vehicle’s tires, which is used to signal low inflation warnings to the driver. The signaling is done via dashboard lamps which indicate a low inflation state for any of the tires. The receiver also monitors the performance of the components in the TPM system and will signal a fault to the driver if the performance of the system is compromised.

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 B, and Industry Canada RSS-210/GEN, were performed on EnTire Solutions, LLC model 218695-102. This device is subject to the Rules and Regulations as a Receiver. As a Digital Device it is exempt, but such measurements were made to assess the receiver's overall emissions. In testing completed on February 9, 2007, the device tested in the worst case met the allowed Class B specifications for radiated emissions by 14.2 dB (see p. 6). The conducted emissions tests do not apply, since the device is powered from a 12 VDC system.

Introduction EnTire Solutions, LLC model 218695-102 was 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, Issue 6 and RSS-Gen, Issue 1, 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. No: IC 2057). 2. Test Procedure and Equipment Used The pertinent test equipment commonly used in our facility for measurements is listed in Table 2.1 below.
