Software update

The "Update" folder is used for updating the firmware on your PROFI TX and
for changing the language pair. You simply "place" the current update in this
folder. The update is performed when the device is switched on again.
1. Download the latest firmware from the Downloads section of our home page.
2. Connect the transmitter to the PC.
3. When the transmitter is connected to the PC for the first time, you must wait
until the automatic driver installation is completed.
4. Open the "PROFI TX" mass storage.
5. Place the update file in the "UPDATE" folder.
6. When updating from version 1 to version 2 with speech output, you must copy
the entire content of the AUDIO folder (three subdirectories: DE, EN, FR) to the
AUDIO folder of the PROFI TX. This process takes several minutes due to the
amount of data.
7. Switch on the transmitter.
The update process starts automatically when an update file is found in the
"Update" folder. The file name of the update is displayed on the transmitter
screen. The annular light "rotates" until the update is completed.
Upon completion of the update process, the transmitter starts as usual.
The update file is deleted automatically.

Switching to normal mode

In charging mode, the PROFI TX logs into the PC as mass storage with the
name "PROFI TX".
Press and hold the power button until the annular ring is fully lit to switch to normal
mode: The PROFI TX logs off from the PC as USB mass storage and logs in again
as a game controller.
Now, you can access the status displays and menus as usual and program
the transmitter.
