CAUTIONS:
1. In the UK Some wireless microphone systems require a license. This
depends on the frequency 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 work
ing 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.
