I'm feeling stupid to ask this, but I am a bit confused.
What exactly are the four pushbutton switches on the right of the meter supposed to do?
In the MC77 I thought the first one selects between GR and Level Metering, the second one between Input and Output Level Metering, the third one sets the unit to hard bypass (input directly to output) and the fourth powers the unit on or off.
In the 1176 it seem like it's GR metering, output level meter -10, output level meter +4, off (I suppose meter off, not the wole unit power off).
I have in front of me two MC77 kits (i know, they have been lying unassembled for much too long) and one hairball 1176 REV A/D kit with mnats rev A board. With the two MC77 kits came four identical pushbutton switches like that one:

with the rev A/D kit, as we can all see, came one of those above and one of these:

So the first confusion is, for the 1176, where the switch should turn the meter of, I have a special 240V switch, while for the MC77, where that would make sense (because it switches the power) I only have those normal switches. The second confusion is, that like with the ratio buttons, they are all interlocking (I hope that is the right word), meaning that even the power switch turns off when I change the metering settings. Is it supposed to do that, because it doesn't seem practical.
In mnats power wiring tutorial the Power transformer wires directly to that switch, so here it switches power, not meter off. But wouldn't the unit power down everytime I change Meter settings (except when I hold the power button while switching)?

Obviously I have never worked on a "real" 1176 or mc77, so I don't know how this should work. I'm sorry if this was already discussed, I did some search but couldn't find answers. Any help would be appreciated. Thanks, Timon
