5, Remove the tonearm setscrews @ and @ .
Then, the tonearm can be removed in the direction of
the arrow. (See Fig. 7)
6. When removing this lift base plate, remove the arm lift
setscrew @) before tuning over the arm base, and then
remove the arm lift. (See Fig. 6)

time.
7. Remove the anti-skating control knob. (See Fig. 6)
8. Turn over the arm base and remove the PU fixing plate.
9. Remove the lift base plate setscrews @) and @. Then,
the lift base plate can be removed.
10. Before mounting the arm base, make sure that the auto-
matic mechanism is in the initial stage, and then shift
the cueing lever of the arm base down in the direction
of the arrow in order to make cueing-up. (See Fig. 7)
