Most users do not need a license to operate a wireless microphone system.
Nevertheless, operating a microphone 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 microphone 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
