FREQUENCY SELECTION GUIDE

The Shure UHF Wireless System is designed for maximum flexibility and versatility

in a variety of applications. Up to 20 Shure UHF Wireless Systems can be operated si-

multaneously in a single installation using the frequency compatibility groups. Groups

A1 and A2 are included in a “master list” that covers all frequencies in the 782 to 806

MHz band. When using the U4D dual receiver, maintain a minimum of 500 kHz separa-

tion between each receiver in the U4D. Please contact the Shure Customer Service De-

partment If you need additional information or assistance in frequency selection and

setup.

COMPATIBILITY GROUPS

The Shure UHF Wireless System includes seven 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.

Use frequencies from Groups 1-3 in locations where TV channels 66, 67, 68, and 69

are NOT in use. If any of these TV channels are present in your location, use frequen-

cies from one of the Groups 4-7 as indicated in the following table. Use the UHF TV

Channel Guide in this supplement to determine which TV channels may be present in

your area.

NOTE: The Group and Channel for any frequency in the UHF band as well as the TV

channel corresponding to that frequency is displayed on the U4 receiver. If the

receiver displays a TV channel that is active in your area for a frequency you have

selected, choose a different frequency.
