Operating the transmitter using the PC
7.3 Software update
The "Update" folder on the PC is used for updating the software on your
PROFI TX and for changing the language pair.
1. Connect the transmitter to the PC.
2. Open the "PROFI TX" mass storage.
3. Place the update file in the "UPDATE" folder.
4. 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.
7.4 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.
