After this is done, reconnect the pitch fader to the main PCB, make sure the pitch fader knob is still centered at zero, and remove the platter and PCB dust cover. Plug in and turn on the deck (do NOT push the start/stop button at any time when the platter is off, it can destroy the motor), then attach the red meter probe to the post next to the motor on the main PCB labelled "TP27." Connect the black meter probe to the post labelled "GND" next to it. Set your meter to read cycles/Hz, then adjust VR301 until the meter reads 262.08Hz, within a tolerance of .05Hz
Now your table is correctly calibrated to factory specs. Put it all back together and enjoy.
