Place the record to be played on the platter.2. Set the SPEED select switch to th

12、e speed atwhich the record is to be played.3. Set the ARM-ELEVATION lever to the UP position.4. Remove the stylus cover and release the armclamp.5. Hold the headshell by the finger lift and movethe stylus across the record to the track youwant played. The platter will begin to rotate.6. Observe the

13、appropriate strip of strobe calibra-tion dots on the platter edge. If the strobe dotis not stationery, finely adjust the platter speedwith the SPEED ADJ. knob according to.HOW TO FINELY ADJUST THE PLATTERSPEED on page 7.7. Set the ARM-ELEVATION lever to the DOWNv position.The stylus will descend slo

At the same time, theplatter stops rotating and the power to theturntable is turned off.10. Secure the tonearm to the arm rest with theclamp and attac

17、h the stylus cover to protectthe stylus.OPERATION PRECAUTIONS. Never obstruct the turntable with the handwhile it is rotating. This may cause damage. Do not force the tonearm closer than 40mm tothe center shaft or outward from the arm rest. Ifthis distance is exceeded, you may damage theinternal mec

18、hanisms and render automaticoperation ineffective.o Be careful not to make the turntable vibratewhile a record is playing since this can result indamage to the stylus and record. Place only one record at a time on the platter.If two or more records are stacked on theplatter, the stylus will not make

19、 proper contactwith the grooves, and this will impair the qualityof reproduction.o Do not disconnect the power cord while thestylus is still in a record groove as this may resultin damage to the stylus and record.o) *!
