Align the headshell pins with the stand grooves and insert. Observe that the headshell length is not greater than the height of the dust cover. This s

11、tand can also be used for storing the EP adaptor. Stroboscope Fine adjustments of rotation speed can be performed with the aid of the stroboscope. Adjust the SPEED ADJ. knobs while observing the pattern indicated bellow. If the rotation is fast, the pattern will appear to move toward the left, while

12、 movement toward the right indicates slow speed. Correct speed is obtained when the pattern appears to be stationary. 33-l /3 rpm Arm Rest Supports the tonearm when not playing a record.

Strobe lamp lights and platter rotates. 3. Depress SPEED button (33 or 45) according to type of record.

14、 4. Employ SPEED ADJ. controls and strobo- scope to adjust rotating speed (required only once per listening session) 5. Disengage arm clamp and gently position the tonearm over the desired portion of the record. 6. Set function lever to DOWN. Stylus will be gently lowered onto the record. 7. Adjust

15、volune and tone controls of the stereo amplifier as desired. 8. At the end of the record, or to interrupt the record, set the function lever to ON-UP. The stylus will be raised from the record. 9. Return tonearm to arm rest and engage clamp. PL.51 C,A 33 SPEED ADJ. Knob Use for fine adjustment of 33

Function Lever This lever incorporates power switch and arm elevation functions. . OFF AC power is cut off. . ON-UP Power is turned ON.

17、When set from DOWN to this position, the tonearm is raised. . DOWN Tonearm is gently lowered. 10. Set function lever to OFF. Power will be cut off and strobe lamp extinguished. 11. It is advisable to replace the stylus cover for protection whenever the tumtable is not in use. OPERATING PRECAUTIONS a

18、 Keep stylus and records clean. Use a stylus brush to clean the stylus and a good quality record cleaner to clean the records each time before and after playing. a Avoid exerting unnecessary force on the tone- arrn. When changing headshells, set the tonearm in the arm rest and engage the clamp. a Ta

19、ke care not to impart vibration to the tum- table while a record is playing. Record and stylus can be damaged. a Avoid placing more than 2 records on the turntable platter while playing records. 3. 3.1 1 PARTS LOCATIONS TOP VIEW Hoadshell stand PNW.073 Outpul cord - PDEO04 (KCrl Fubber grommet (A) P
