For all you who, like me, are looking for the answer how to update the firmware. It is hidden on the last page of the manual:
- Turn the radio off.
- Plug the cable firmly in your device and PC.
- Press and hold side buttons 1 and 2 (the CALL and PTT buttons) and switch phone on. Screen will come on with no display.
- Start the UPDATE.EXE, choose and load the .sgl file and click DOWNLOAD.
That is it…
