Updating a DFR Series Radar

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.

Updating with Unit Connected to a PC

Step 1. Open the tool launcher and wait for the splash screen to be presented.

Step 2. Attempt to read current version. It will attempt to read with no success.

    Step 3. Press the “Start Download” button. Since there is a unit connected, it will open your file explorer for you to select the most recent data.

Step 4. Once data is selected, press “Start download”, and the progress bar will begin to move.

Step 5. Once the download is complete, you will see the following prompt presented saying that it is finished. Press “OK” to close this prompt.

Step 6. Despite pressing “Read Version”, it still will not display a version. When the unit is powered on (and disconnected from the PC), the database will show the file just downloaded to the unit.

Updating with Unit Disconnected

(Note: this process is strictly to demonstrate possible errors you may encounter.)

Step 1. Open the tool launcher and wait for the splash screen to be presented.

Step 2. Attempt to read current version. It will attempt to read with no success.

Step 3. Press the “Start Download” button. Since there is not a unit connected, it will show the download has failed. This is normal, and the unit will need to be connected.
