Onkyo TX-SR674 calibration microphone help (1 Viewer)

[equalizr458]

I have a aquired an Onkyo TX-SR674 and I’m having a heckuva time trying to find what calibration microphone it actually used?
No in the manual or service manua.
I cannot find anything anywhere does anybody have any idea which microphone I need
The only thing I see in the original manual is its a puck shape not the little tower microphone that i see a lot

Any reason to believe the mic shown in the manual is not the correct one?
