Hi, perhaps this is not what you were looking for, but there is a button you can click to switch modes, albeit not keyboard key combo. This is on the 182. Notice the M/U/O? You have to, though, first make the mode selection, then turn on PZB. Hope this helps. Cheers, Prof.
Yes indeed that help by knowing there is no keys combo to switch between O/M/U PZB mode, I do that with the switching buttons either on the BR143/146/185/182. Thanks for the BR182 where it is located.
