Yesterday I updated to firmware 1.1.9 but now the lower buttons have a malfunction. If I press RADIO SETTING1 the SYSTEM SETTING menu appears.. if I press EXIT .. the RADIO SETTING1 menu appears regularly. If I press RADIO SETTING2 the MEMORY menu appears.. if I press EXIT RADIO SETTING2 appears regularly. Unfortunately, as regards the CW menu (KEY button) now the two buttons on the left do not work correctly and I cannot change the type of button or speed. If instead I connect a mouse to the USB port and select the various menus from the display .. everything works regularly. I also tried to do a FACTORY RESET and return to the old firmware (1.1.7) but the problem remains. Has this happened to anyone of you?
