the receiver to incorporate additional features and enhancements. New versions of the firmware can be uploaded and installed
using the Shure Update Utility tool, which is available from the Shure Update Utility page.

When you update receiver firmware, update your transmitters to the same firmware version to ensure consistent operation.
