REPLACE THESECOMPONENTS WITH SONY PARTS WHOSE PART NUMBERS AP-PEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB-LISHED BY SONY.SAFETY CHECK-OUT

7、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 for AC leakage.Check leakage as described below.LEAKAGE TESTThe AC leakag

8、e from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn to chassis, must not exceed 0.5 mA (500 microampers).Leakage current can be measured by any one of three methods.1. A commercial leakage tester, such as the Simpson 229 or RCAWT-540

9、A. Follow the manufacturers instructions to use theseinstruments.2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.3. Measuring the voltage drop across a resistor by means of a VOMor battery-operated AC voltmeter. The “limit” indication is 0.75V

10、, 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 digitalmultimeters that have a 2V AC range are suitable. (See Fig. A)Fig. A. Using an AC voltmeter to check AC leakage.0.15FTo Ex

18、 and anti-skating dial.Failure to complete these adjustments will result ininferior sound quality and may cause permanentdamage to the stylus and record.1Make sure the turntable is level.2Set ANTI-SKATING to “0.”01234567ANTI-SKATING3Set the cueing lever to the down position.4Turn up the protective c

19、over to expose the stylus,and move the tonearm to the space between thearm stand and the platter.Take care not to damage the stylus.5Balance the tonearm by turning the counterweighteither clockwise or counterclockwise.When the tonearm is properly balancedIt will remain level with the platter when re

20、leased.It should not tilt in the direction of either the headshellor the counterweight.6Return the tonearm to the arm stand.7A properly balanced tonearm has a tracking forceof zero. Therefore, rotate the tracking force scalering until “0” is aligned to the index line.Restrain the counterweight with

21、your other hand sothat it does not rotate along with the scale ring.0Index line8When you use the supplied cartridge, turn thecounterweight counterclockwise one full rotation,and then continue turning it until the index linecomes to 1. Since one full rotation of thecounterweight yields a tracking for

22、ce of 3 grams,this adjustment results in a tracking force of4 grams, which is the normal requirement for thesupplied cartridge.You can set a tracking force of 3 to 7 grams.1When optionally available cartridge is usedThe tracking force scale ring is marked in 0.1-gramunits. One full rotation yields a

23、 tracking force of3 grams.9Set ANTI-SKATING to the same value as thetracking force scale ring.The numbers on the ANTI-SKATING dial indicatethe number of grams in tracking force.Turn this ring so that the“0“ lines up with the indexline.Turn the counterweightcounterclockwise one fullrotation, and then
