Jeff's got you pointed in the right direction.

Your KEM RS is from 1983 and should have a more modern counter, or perhaps
even the universal couner: K-521. If so, this makes matters pretty easy.

If you open the front panel and look at the board connected underneath the
control switch (fwd and rev) you should notice a switch on the far left of
the board that says 24/25. To the right of that switch is a "pot" as Jeff
described it, or a trimpot. If you get a small flathead screwdriver you
can adjust it.

To check speed, put the film in the track. Mark an X on the frame in the
gate and zero your counter. Run the KEM forward in the 24 fps fwd detent
stopping at 6' or 240 frames. You can check the distance between the two
Xs on a gang sync or manual counter for accuracy, knowing that you were
running the KEM at the 24 fps detent. Or make yourself a 1 minute piece of
film, marking start and end frames with an X. At 1 minute it should read
1440 frames (or 36 feet).

Next, track down a manual. Eagle Eye or Atomic Film should have one to
sell you.
