Step-by-step guide

  1. If not already done, Create compatible USB stick and extract the configuration file(s) to the root of the USB stick in folder called sw_config
  2. If you are using 4.3x software version or newer, then create a file called USB_PASSWORD to the root of the USB stick and enter text yellow_zone into it.
    Note* remove any file extension from the file name, so if the file extension is .txt (USB_PASSWORD.txt), remote the .txt so that the file is called just USB_PASSWORD
    Note** By default Windows is hiding file extension .txt, so be sure that you have selected proper windows settings for the file extension showing (see picture, where Windows settings are correct - "File name extensions" is checked and "Hide extension for known file types" is un-checked.), remove the .txt so that the file is called just USB_PASSWORD
