License Holder:Corso Ltd. Address:1425 Louis Ave. :Elk Grove, IL 60007 : Manufacturer:Same as Applicant : : : Test Result : COMPLIANT This report without appendices consists of 9 pages. Appendix A contains test photos, and Appendix B contains original test data. The data contained in this report reflects only the items tested in the configurations and mode of operations described. An attempt has been made to arrange the EUT, with the equipment provided, into a test configuration which maximizes the observed emissions of the EUT while simulating, as close as practical, a typical end-use installation. Underwriters Laboratories Inc. authorizes the above company to reproduce this report provided it is reproduced in its entirety. Underwriters Laboratories Inc.333 Pfingsten Rd.
