Can't speak for all of them, but in my opinion the first thing to do, when using an unknown "system" (software, keyboard, thermostate, TV-box etc), is to read the user manual. Not talking about a reference manual or technician manual. Safety, operational instructions, general maintenance, features, all stuff you need to know about many devices. And also: for a complex device like e.g. a Tyros 5 or Genos, it is almost impossible to "discover" all of its functionality by just exploring yourself. I've found many relatively unknown features in keyboards, printers, smart-TV's etc. just by reading the manuals. I've read the user manuals from every keyboard I've owned, every TV, amplifier, washing machine, you name it. And perhaps I'm just a very lucky guy, but I can hardly recall any premature broken devices. Perhaps because I use and maintain them as intended. Or just plain luck, who will tell
But manuals, yeah, people should
read 'm more often. It'll often pay off in the long run.
