2  Hello, I just bought the H-777 Pack. Unfortunatelly, there is no User-Manual in my language. Can you please send the Link for the German Usermanual in PDF? -> Thanks I already read the english user manual. I tried to activate the VOX-Functionality as described: I pressed the PTT-Button and the one below (monitor). I kept both on hold. Afterwards I turned the radio on, while beeing on channel 1. The radio just turns on. There is no note that VOX is beeing activated or anything else. Can you tell me how to turn it on? Best regards
