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