EHX Free Speak II: How do I upgrade beltpacks (1.9G and 2.4G) using a USB cable from EHX?
- In EHX go to "Tools" and click on "Apply Wireless Firmware via USB" - Plug the USB cable between the PC running EHX and the beltpack. Make sure the beltpack is ON and registered.- Load the .fws file onto the newly opened EHX window and click on "Update Firmware"- It takes about five minutes per pack to complete the upgrade process
