The EUT consists of a transmitter inside a keyboard which communicates with a receiver that connects to the PS/2 keyboard port on a personal computer. Y-RE20 is the unit with the most features. Y-RF21 is the same as Y-RE20 with the scroll wheel removed and a different volume control knob. Modifications:The EUT was not modified during the testing. Manufacturer:Logitech, Inc. 6505 Kaiser Drive Fremont, California 94555-3615 Test Date(s):May 16 and 18, 2001 Test Specifications:EMI requirements FCC Title 47, Part 15 Subpart B, Class B Test Procedure: ANSI C63.4: 1992. Test Deviations:The test procedure was not deviated from during the testing. SUMMARY OF TEST RESULTS TESTDESCRIPTIONRESULTS 1Conducted RF Emissions, 450 kHz - 30 MHz. Complies with the Class B limits of FCC Title 47, Part 15 Subpart B. 2Radiated RF Emissions, 26.96 MHz - 27.28 MHz. Complies with the limits of FCC Title 47, Part 15 Subpart C. (Section 15.227) 3Radiated RF Emissions, 30 MHz - 1000 MHz. Complies with the Class B limits of FCC Title 47, Part 15 Subpart B.

PURPOSE This document is a qualification test report based on the Electromagnetic Interference (EMI) tests performed on the RF Keyboard Models: Y-RE20 & Y-RF21. The EMI measurements were performed according to the measurement procedure described in ANSI C63.4: 1992. The tests were performed in order to determine whether the electromagnetic emissions from the equipment under test, referred to as EUT hereafter, are within the Class B specification limits defined in FCC Title 47, Part 15, Subpart B. The EUT was also tested to determine if the electromagnetic emissions were within the limits defined in FCC Title 47, Subpart C, Section 15.227.
