the power switch of the piayer.(Refer to page 11.}
4.Set the player to the play mode.
5.Measure the DC tevel (AmV) displayed on the
oscilloscope.
@lf the value of A is within the range of + 60mV , the
turntable height is correct. If it is not within this range ,
make the necessary adjustments using the 0.9mm feeler
gauge (RZZ0297).
If Ais more than +60mvV , make the turntable lower.
If Ais less than -60mV , make the turntable higher.
MECHANICAL ADJUSTMENT
1.Connect CH1 of the oscilloscope to TJ101 (+) and GND
(-) of the servo P.C.B.
Oscilloscope setting: VOLT 200mV
SWEEP.....0.5ysec.
2.Set the test disc (SZZP1056C) and turn ON the power
swith of the player.(Refer to page 11.)

0.9 mm feeler
gauge (RZZ0297)
B.Loosen the turntable set-screw.
C.Adjust turntable height to 0.9mm with the feeler gauge
as shown above.
D.Tighten the turntable set-screw by using the 1.27mm
hexagonal wrench.
E.Check the turntable height adjustment by following
steps 1 ~ 5 above.
4.Monitoring RF signal on the oscilloscope, adjust the two
adjusting screws aiternatelywith the 2.0mm hexagonal
wrench so that the vertical fluctuation of RF signal is
minimized and the eye pattern is most stretched.
5.Turn OFF the power switch of the player.
6.After the adjustment, apply screw lock paini(RZZ0L01)
