Found these in my 694 case

[Ewor]

2 identical “buttons” one side is slightly domed, the other is side is flat. Found in a clear plastic bag-no mention in instructions.

What are they???

As above , they are the round discs you remove to allow the ejector arms to come out …..

They are spares

Good idea to provide spares, I dropped one on the garage floor last week, it adds urgency to the search when you haven't got any spares

BTW, you obviously have not given the aforementioned 694 a good clean
