Cal,
I have the paper work in front of me and the 3.000 is followed by an H, I read that as 3 hours labor.
The parts replaced are listed on the next 'line' Sensor cover glass, adjust rangefinder clean, lubrication and adjustment leather covering. followed by 1 PCS which I take to mean 'pieces'.
Then the next line; printed circuit, adjusted that is followed by that same 1 PCS which is a little strange as if its labor why would it be listed a a part.
Ahh the mysteries of someones IT system...
