7、N THIS MANUAL OR IN SUPPLEMENTS PUB- LISHED BY SONY. SAFETY CHECK-OUT After correcting the original service problem, perform the follow- ing safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts

8、for AC leakage. Check leakage as described below. LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microampers). Leakage current can be measured by any one of thr

9、ee methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resist

10、or by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a pas- sive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC ra

11、nge are suitable. (See Fig. A) Fig. A.

Make sure the two pins on the bottom of the platter are properly inserted into the two holes in the motor, as indicated by the arrows in the illustration above. 2Place the slip mat on the platter. 3Slide

17、the counterweight onto the shaft at the rear of the tonearm and turn 3 or 4 times in the direction of the arrow. 4Insert the headshell into the end of the tonearm. Turn the locking ring in the direction of the arrow until the headshell is secure. 5Insert the hinges on the dust cover into the hinge p

18、ockets on the rear of the cabinet. 6 Getting Started Adjusting the Turntable Before attempting to play any records, be sure to complete the following steps to properly adjust the tonearm balance, tracking force and anti-skating dial. Failure to complete these adjustments will result in inferior soun

19、d quality and may cause permanent damage to the stylus and record. 1Make sure the turntable is level. 2Set ANTI-SKATING to “0.” 0 1 2 3 4 5 6 7 A N T I - S K A T I N G 3Set the cueing lever to the down position. 4Turn up the protective cover to expose the stylus, and move the tonearm to the space be

20、tween the arm stand and the platter. Take care not to damage the stylus. 5Balance the tonearm by turning the counterweight either clockwise or counterclockwise. When the tonearm is properly balanced It will remain level with the platter when released. It should not tilt in the direction of either th

21、e headshell or the counterweight. 6Return the tonearm to the arm stand. 7A properly balanced tonearm has a tracking force of zero. Therefore, rotate the tracking force scale ring until “0” is aligned to the index line. Restrain the counterweight with your other hand so that it does not rotate along

22、with the scale ring. 0 Index line 8When you use the supplied cartridge, turn the counterweight counterclockwise one full rotation, and then continue turning it until the index line comes to 1. Since one full rotation of the counterweight yields a tracking force of 3 grams, this adjustment results in

23、 a tracking force of 4 grams, which is the normal requirement for the supplied cartridge. You can set a tracking force of 3 to 7 grams. 1 When optionally available cartridge is used The tracking force scale ring is marked in 0.1-gram units. One full rotation yields a tracking force of 3 grams. 9Set

24、ANTI-SKATING to the same value as the tracking force scale ring. The numbers on the ANTI-SKATING dial indicate the number of grams in tracking force. Turn this ring so that the “0“ lines up with the index line. Turn the counterweight counterclockwise one full rotation, and then a little more until t

25、he index line is aligned to 1. 55 SECTION 2 DIAGRAMS Note on Printed Wiring Board: X : parts extracted from the component side.

After you have finished using the adaptor, return it to the adaptor tray. Using the PITCH BEND + and buttons You can use the PITCH

38、BEND + and buttons to synchronize the beat of the selection playing on one turntable with the beat of another selection playing on the other turntable. You can use these buttons even if the QUARTZ lock button is turned on or off. 1Use the PITCH ADJ. knob to synchronize the speed of the selection pla

39、ying on one of the turntables with the speed of the selection on the other turntable. 2Press the PITCH BEND + and buttons to synchronize the beat of both selections. Pressing and holding down the + or button causes the selection to play 10% faster or slower than the normal playing speed. zIf the str

40、obe dots are not stationary when the PITCH ADJ. knob is set to the center position Adjust the platter speed by sliding the PITCH ADJ. knob toward + or until the strobe dots become stationary. zIf you have an extra headshell, keep it in the headshell holder.
