Where to Find the DFR Tool Download

The download can be found at: Uniden Support - Downloads and Manuals by entering your model number and pressing enter. 

On your model's page you will be presented with a few different options. The specific file you are looking for will be titled "SW_Download_Tool_Vxxx.zip". Download the file and run the set-up wizard until you are presented with the launcher shown in step 1 of the next section.
