Place the record to be played on the platter. 2. Set the SPEED select switch to the speed at which the record is to be played. 3.

17、 Set the ARM-ELEVATION lever to the Up r position. 4. Remove the stylus cover and release the arm clamp. 5. Hold the headshell by the finger lift and move the stylus across the record to the track you want played. The platter will begin to rotate. 6. Observe the appropriate strip of strobe calibra-

18、tion dots on the platter edge. If the strobe dot is not stationery, finely adjust the platter speed with the SPEED ADJ. knob according to .HOW TO FINELY ADJUST THE PLATTER SPEED on page 7. ARM-ELEVATTON LEVER (ARM-ELEVATTON) This lever controls the ascent and descent of tne tonearm. ARM REST Set the

19、 tonearm on its rest when it is not playing records. cs Closing the clamp Releasing the clamp SPEED ADJUSTMENT KNOB (SPEED ADJ.) Perform fine adjustment of the Speed of a record being played with this knob, while looking ar the strip of strobe calibration dots on the platter edge. SPEED SELECT SWTTC

20、H (SPEED) Push this switch to set the platter to 45rpm and release for 33-.1 13rom. 7. Set the ARM-ELEVATION lever to the DOWN v position. The stylus will descend slowly to the record and play will begin. 8. Adjust the volume and tone controls on the amplifier to the preferred levels, and then sit b

21、ack and enjoy your record. 9. After the record has been played, the auto- return mechanism is actuated and the tonearm returns to the arm rest. At the same time, the platter stops rotating and the power to the turntable is tumed off. 10. Secure the tonearm to the arm rest with the clamp and attach t

22、he stylus cover to protect the stylus. Releasing the clamp PL.s1B 3.

The tonearm is moved frorrr the arm rest to above the turntable. 2. Lever A, connected to the tonearm. unlocks Iever B, and the

25、 microswitch is turned ON (Fig. 1). 3. When the microswitch is turned ON, the motor is started and the turntable Lregins to rotate. r t q . I 4.2 AUTO-RETURN DETECTION 1. When the stylus nears the center shaft, lever A contacts lever C (Fig. 2). Turntable tl. 7. Plate B atop plate A is moved toward

26、sear A by the movement of plate A. Ihe front end of plat,e B moves approximately 0.1mm when the stylus is advanced 1mm toward the center shaft by one revolution of the record. fhe tooth of gear A has the dimensional clif- ference shown in Fig. .1-a. Plate B is pushed back by this dimensional dif- fe

27、rence at a stylus movement of within 1mm per revolution of the record. When the stylus enters the iead-otit groove rn the record at the end of the performance, it is moved 4mm toward the center shaft by one revolution of the record. The end of plate B contacts tl-re tooth of sear A (Fig. a-b). Gear

28、A and gear B are engaged, and gear B is turned by rotation of the turntable. Lever A F i s . 3 F ig. 4-b 4.3 AUTO-RETURN OPERATION 1. Gear B is rotated by detection of auto-return. 2. Lever D moves along the groove of gear B, and the tone arm is lifted (Fig. 5). Lever A is pushed and the tonearm to

29、the arm rest by lever D (Fig. 6). F i s . 5 is returned _, -i. F i s . 6 When gear B has rotated one revolution, lever D is returned to its original position. When lever D has returned to its original posi- tion, lever B is pushed by lever A and the microswitch is turned OFF (Fig. 7). When the micro

30、switch is tumed OFF, the motor is stopped, and the turntable also stops. PL-51El 4.4 ADJUSTMENT 4.4.1 Auto-return Detection Position 1. Plate B contacts the tooth of gear A, the turn- table is rotated, and the auto-return detector is reset. Plate B Fis.8 Adjust the adjusting screw so that plate B co

32、as shown in Fig. 10-a when the tonearm is fastened to the arm rest. 2. Adjust the adjusting screw (Fig. 10-c) so that Iever B and the microswitch are positioned as shown in Fig. 10-c when the tonearm is fastened to the arm rest. 3. Since this adjustment will adversely effect the auto-return detectio
