Are any of these Soyuz controls involved in separating the orbital module?

According to this Q & A, it's very likely that the Soyuz spacecraft's orbital module can be manually separated independent of other spacecraft operations.



On this CollectSpace page, there's an excellent photo of a bank of Soyuz control panel buttons with guards to protect against accidental activation of critical functions:



4 by 4 array of buttons, each row with a common metal guard plate, lifted up in the picture. Each button is labeled in abbreviated Cyrillic text.



I note that three of the buttons (#3, #12, #13) are labeled with "БO", the abbreviation for бытовой отсек (bytovoi otsek), or Orbital Module. I don't know any Russian, so I can't tell what the remainder of the labels say. It looks like buttons #12 and #13 are labeled very similarly if not identically.



Are any of these labels plausibly interpretable as "separate/jettison/disconnect orbital module"?



Any transliteration/translation/interpretation of the other controls is welcome in addition.

    @coredump: You really don't want to jettison the service module before you perform the reentry burn.

    The 12th and 13th Critical Command Keys "ОТСТРЕЛ БО" are БО (Orbital Module) Jettison.




    The БО separation (jettison) can be executed either automatically on
    the nominal separation schedule within the unified cyclogram or on the
    ОВК12 and ОВК 13 Critical Commands in case of the urgent descent
    before the СКД (Orbital Maneuver Engine) ignition for retrofire.




    Perhaps you have to press them both simo? (Still checking on that.)

            The 12th and 13th Critical Command Keys "ОТСТРЕЛ БО" are БО (Orbital Module) Jettison.




            The БО separation (jettison) can be executed either automatically on
            the nominal separation schedule within the unified cyclogram or on the
            ОВК12 and ОВК 13 Critical Commands in case of the urgent descent
            before the СКД (Orbital Maneuver Engine) ignition for retrofire.




            Perhaps you have to press them both simo? (Still checking on that.)

            This is all I can find from there on the Critical Command Keys.

              I wonder if any of the agencies considered pictographs/iconography for controls on international missions.

            • I'm having trouble finding a good gloss; Google translate gives ОТСТРЕЛ -> "dismissed" for uppercase and отстрел -> "shooting" for lowercase.

              The duplication of the OM jett control is really interesting -- is it really the most drastic of these operations, that it requires the extra guard of simultaneous press?
