PANEL FACILITIES AND OPERATION STROBE LIGHT This light comes on when the platter starts to rotate and

12、it lights stroboscopically (Refer to HOW TO FINELY ADI UST I Ht PLATTLR SPLTD on page 7). OPERATION 1. 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. Set the ARM-ELEVATION lever to the UP position. 4. Remove the stylu

13、s 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- tion dots on the platter edge. If the strobe dot is not stationery, fi

14、nely adjust the platter speed with the SPEED ADJ. knob according to .HOW TO FINELY ADJUST THE PLATTER SPEED on page 7. 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 t

15、he preferred levels, and then sit back and enjoy your record. 9. After the record has been played, the auto- retum mechanism is actuated and the tonearm ARI4-ELEVATION LEVER (ARM.ELEVATION) This lever controls thc ascent and descent of the tonearm.

Secure the tonearm to the arm rest with the clamp and attach the stylus cover to protect the stylus. OPERATION PRECAUTIONS . Never obst

18、ruct the turntable with the hand while it is rotating. This may cause damage. . Do not force the tonearm closer than 40mm to the center shaft or outward from the arm rest. If this distance is exceeded, you may damage the internal mechanisms and render automatic operation ineffective. o Be careful no

19、t to make the turntable vibrate while a record is playing since this can result in damage to the stylus and record. . Place only one record at a time on the platter. If two or more records are stacked on the platter, the stylus will not make proper contact with the grooves, and this will impair the

20、quality of reproduction. o Do not disconnect the power cord while the stylus is still in a record groove as this may result in damage to the stylus and record. o) * ! J r PL-s1 i e)3.

(2) Disconnect the white wire connected to the NE terminal of the power supply board. (3) Remove

22、 the 4 allen head wood screws. (4) Disconnect the PU cord (OUTPUT cord) connector. (5) Disconnect the SPEED selector switch wiring. (6) Disconnect the ground wire. t , Lever D Fis.6 When gear B has rotated one revolution, lever D is retumed to its original position. When lever D has returned to its

23、original posi- tion, lever B is pushed by lever A and the microswitch is turned OFF (Fig. 7). When the microswitch is tumed OFF, the motor is stopped, and the turntable also stops.

Adjust the adjusting screw (Fig. 10-c) so that lever 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
