Under a new FCC rule, anyone who uses a wireless microphone (or similar device) that operates in the 700 MHz Band must stop operating their wireless microphone (or similar device) no later than June 12, 2010.
    All users of 700 MHz Band wireless microphones (and similar devices) who wish to continue to use their equipment – including users such as theaters, churches, schools, conference centers, theme parks, and musicians – will need to retune or replace, if necessary their equipment no later than June 12, 2010. Wireless microphones (and similar devices) that operate outside of the 700 MHz Band are not affected by the FCC’s actions and may continue to operate.
