10、fore your turntable is shipped from the factory, the switch is set to the power re- quirements of the turntables destination, check that it is st properly before plugging the power cord into the outlet. lf the voltage is not properly st or if you move to an area where the voltage requirements differ

11、. adjust the selector switch as follows: 1. Oisconnect the Dower cord, 2. Provide yourself with a medium-sized screwdriver. Insert the tip of the screwdriver into the groove of the selector switch and turn it so that the power voltage marking of your area points to the white mark by the arrow on the

PANEL FACILITIES f- rE O srnnr BUTToN When this button is depressed, the power is turned on to the turntable, the strobe light comes on and the platter starts to rotate. with the REcoRD slzE SELECToR set at one of the positions - 30, 25, or I7 - the tonearm moves automatically

13、to the record disc as the platter starts rotating, thus starting record play REPEAT BUTToN Push this button when you want to listen to the same re- cord again. Press the button once more to release. NOTE: All you have to do fot repeat play is to prcss the REqEAT button. Therc is no need to push the

14、START and CJT button again. CUT BUTToN lf this button is depressed whil the record is playing, the tonearm automatically returns to the arm rest. and the power to the turntable will be cut off.

STROBE LIGHT This light comes on when the tonearm moves awav from the arm rest toward the platter. lt irradiates the strobo- scope around the outside of the platter. O TONEARM This tonearm is

18、designed to apply the correct tracking force to the cartridge and to keep this force at the precjse level for faithful tracking of the record grooves.

NOTE: When the ARM ELEVATION lever is set to the UP position for automatic play, the toneam will move over as fal as the lead-in groove on the record but it will not descend and the rccord will therefore not be pl

20、ayed. ANTI.SKATE KNoB This knob is used to cancel out the harmful skating force which is geneiated during record play. For further details, see ANTI-SKATING ADJUST- I4 E NT . nnru REST/CLAMPER The arm rest supports the tonearm when it is not being used. Set the tonearm on its rest when it is not pla

21、ying re- cords. Clamp it into position if you dont have any im- mediate plans to play records. O PLATTER/RUBBER PLATTER MAT When the tonearm is moved and power is supplied to the turntable, the platter will start rotating at the set rotation speed. The rubber platter mat stabilizes the records and a

22、lso absorbs external vibration. DUST coVER Keep this closed unless operating the controls or tonearm, or changing over records. This serves to keep dust from adhering to the records during record play. When fully opened and pulled straight up, this dust cover can be re- moved from the cabinet. r 5 3

26、ADJUSTMENTS 4.1 D.D MOTOR OPERATION ADJUSTMENT l. Rotate the tumtable platter. 2. Connect a dual-image oscilloscope (or synchro- scope) to the TP3 and Q2 terminals of ttre cir- cuit board assy. 3. Adjust VR1 (for 33-1/3 rpm) and VR2 (for 45rpm) on the circuit board assy in order to bring the rising

28、as shown in Fie. 4-4. Fis. 44 o Tonearm lowering position Tonearm lowering position is adjusted by tum- ing an adjustment screw located in the hole at the base of the tonearm (see Fig. 4-5). Tum the screw clockwise to move the lowering position inwards. Tum the screw counterclockwise to move the low

29、ering position outwards. This adjustment may be simplified by using a test record . Fis.4-6 o Tonearm misoperation If the tonearm should happen to stop midway during the lead-in operation, adjust the nut shown in Fig. 4-7. This nut should be neither too tight, nor too loo6e.
