Nevertheless, operating this micro- phone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless mi- crophone systems, and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones. To operate wireless microphone systems at power greater than 50mW, you must qualify as a Part 74 user and be licensed. If you qualify and wish to apply for a license go to: http://www.fcc.gov/Forms/Form601/601.html Digital Hybrid Wireless Belt-Pack Transmitter Rio Rancho, NM 3 Introduction The design of the LMb transmitter delivers the ad- vanced technology and features of Digital Hybrid Wire- less ® in a Lectrosonics belt-pack transmitter at a modest cost.
