FREQUENCY SELECTION GUIDE
The Shure UHF Wireless System is designed for maximum flexibility and ver-
satility in a variety of applications. Up to 19 Shure UHF Wireless Systems can be
operated simultaneously in a single installation using the frequency compatibility
groups. Please contact Shure Brothers Incorporated if you need additional infor-
mation or assistance in frequency selection and setup.
Compatibility Groups
The Shure UHF Wireless System includes 12 groups of compatible channels. If you
are using more than one receiver in the same area, we recommend that you set the
receivers to different frequencies within the same group.
Compatible Frequency List
The following table lists the frequencies in each of the twelve compatibility
groups.
