Wireless Designer
Software
Download the Wireless Designer software installer from
the web sites under the SUPPORT tab at:
https://www.lectrosonics.com/wireless-designer.html
Wireless Designer only needs to be installed the first
time the software is used. Once the software is installed,
updates are available by simply clicking on an item in
the Help Menu.
Note: If Wireless Designer is already installed,
you must uninstall it before attempting to install
a new copy.
Firmware Update
Instructions
Firmware updates are made with a file downloaded from
the web site and the DHu connected via USB.
The USB port on the transmitter requires a micro-B
male plug on the connecting cable. The other end of the
cable would normally be a USB A-Type male connec-
tor to fit the most common type of USB jack used on
computers.
