No. 1.1 2 SUMMARY GENERAL REMARKS: The Wheel electronic consists of a 125 kHz Receiver and a 433 MHz Transmitter therefore contains this test report the transmitter tests according to FCC Part 15, Subpart C, Section 15.231 and the receiver tests according to FCC Part 15, Subpart B. All radiated tests have been performed on samples which are in original state. For activating the EuT it has been laid into a pressure box where it was possible to change the pressure. All other tests have been performed at PCB without any cabinet where it was possible to activate the EuT when we switch on the DC power with an external DC Power supply. FINAL ASSESSMENT: The equipment under test fulfills the EMI requirements cited in clause 1 test standards. Date of receipt of test sample : acc. to storage records Testing commenced on : 05. March 2007 Testing concluded on : 12.
