Special note regarding LT and LT/E01 firmware:
The LT and LT/E01 models require different firmware loads. The LT is sold in the US and Canada; the LT/E01 is sold in the European Union. Be sure to download the correct update file and double-check before installing!

Please note that there are two versions of LT/E01 firmware. Units with version 1.xx firmware currently installed can only be upgraded to the latest v1.xx firmware; units with version 2.xx firmware installed can only be upgraded to the latest v2.xx firmware.

Please note: version 6.x firmware for the LT is for use only in new product shipped after October 13, 2018 to US customers. These will bear the following new FCC ID numbers:

These ID numbers indicate conformance to the ETSI standard now in effect for wireless microphone transmitters in the United States and Canada. Here the "Nu Hybrid" compatibility mode replaces the old "400" mode used in previous versions of the product.
