Bob: Your experiences and similar ones are the reasons this group exists. For me, the Manual 2.2 is deficient in many ways which I won’t mention here - well, just one: There is no mention of the FM Commercial Band Radio accessible from the Settings. It is excellent (entering a frequency manually requires “backspacing” o.1MHz) and I can’t figure out how to set the 5 “push button” settings at the bottom of the display.
I don’t have the DMR module and after watching the Chinese video on howto istall it, I probably will not try. But the Russian reviewer identifies your problem and mentions a workaround which I didn’t quite understand. You can read my translation posted In the Weblinks section (Topic).
I have a long list of deficiencies and corrections to Manual 2.2.
