When I turn on my Ramsa DA-7, the SOLO LED is ON, but no SOLO buttoms are activated on the mixer? It happend also a month ago, but now the problem is back, so I cant use the mixer in normal mode
Is there some kind of "RESET" mode?

ps: Its years ago I have used the mixer last time, and after a short while one month ago, the memory battery was down so it went back to 48Khz default setting (I use 44.1 for my Fostex D-160 recorder) but I succeded to change the battery. Quite easy, but you have to loosen a lot a screws, several of them was a little rusty.

yes, there is a reset process.
