Fed 2 RF adjustments ?

[giovatony]

Can anyone refer me to a site that explains how to adjust the RF?
I`ve done the Zorki`s successfully but I don`t see the same slotted screw under the access screw to the left of the RF window as on the Zorki`s.
Thanks,
John

It's under the center screw below the E in Fed.

Mine is a fed 2 variant with Fed written in both Cyrillic and Latin and the center screw is located under the F however upon removal of theaccess screw I see nothing in there even with a small flashlight . This hole is much smaller than the access hole on the Zorki.
Is there a slotted rod type screw in side that could possibly be bent and / or will I have to remove the top to find out?

Found it! Couldn`t see it but immediately after probing with a 1.2 mm screwdriver I fit the blade right into the screw slot , marked the blade angle and the slight tilt of the screwdriver shaft and when I took another look with the torch I could see the edge of the screwdriver slot.
I really need to find tune this RF because the camera works like a dream , smooth and quietly.
Thanks for the help Grehound man.
