CAUTIONS:
1. Some wireless microphone systems require a license. This depends on the fre
quency of the system and the country in which it is to be used. It is the
responsibility of the user to establish if a license is required. As a guide, for the
UK and Europe, VHF radio microphones between 173.800 and 175.000 MHz, or
UHF microphones between 863 MHz and 865 MHz do not need a license. This is
for microphones working at normal power (10mW ERP hand-held or 50mW ERP if
body worn). All other use on alternative frequencies needs a license. More
information on this can be found at : www.jfmg.co.uk/jfmgecom/default.aspx .
If in any doubt, users are advised to investigate the licensing requirements for their
region.
