To verify which firmware version is on your Pro series detector, simply hold the middle button on top of the unit (Display / Lockout) before you turn on the unit.
Download the Radenso Updater Application and launch the updater.
Connect the Radenso Pro/ProSE/Pro M with your PC using the USB data cable. After you plug the radar detector in, your PC should recognize the radar detector. If connected correctly, the last five digits of the radar detector's serial number will be displayed in the updater program, and the serial number status icon will be green.
Note: Upon the initial firmware update, your serial number may have to be entered once manually and will be recognized automatically with future updates.
If the serial number is correctly displayed and the status icon is green, click on the "download" button to start the firmware update process.
After the download is complete, click "OK" and exit the updater program. You may now disconnect your radar detector from the computer, and your firmware has been updated successfully.
