TAPE DECK ADJUSTMENTS

1. HEAD REPLACEMENT

•After replacement, demagnetize the heads by using a degausser.

•Be sure to clean the heads before attempting to make any adjustments.

•All wiring should be returned to the original position after work is completed.

2. HEAD AZIMUTH ADJUSTMENT

PLAY

(1)Load the test tape(VTT-703, etc., 10 kHz) for azimuth adjustment.

(2) Press the PLAY button.

(3)Use a cross-tip screwdriver to turn the screw for azimuth adjustment so that the left and right output are maximized.

(4) Press the STOP button.

(5) After completion of the adjustment, use thread lock(TB-1401B) to secure the azimuth-adjustment screw.

HEAD AZIMUTH ADJ.

TEST TAPE

3. MOTOR SPEED ADJUSTMENT

(1)Insert the test tape(TCC-119, etc., 3,000 Hz).

(2)Press the PLAY button.

(3)Use a flat-tip screwdriver to turn the SVR(located inside the rear of the motor) to adjust SVR so that the frequency counter become 3,000 Hz.

MOTOR SPEED ADJ.

4. CHECKING THE MECHANISM TORQUES AND TENSION

• Clean the head, capstan and pinch roller before making any measurement.

PRODUCT SAFETY NOTICE

EACH PRECAUTION IN THIS MANUAL SHOULD BE FOLLOWED DURING SERVICING. COMPONENTS IDENTIFIED WITH THE IEC SYMBOL ! IN THE PARTS LIST AND THE SCHEMATIC DIAGRAM DESIGNATE COMPONENTS IN WHICH SAFETY CAN OF SPECIAL SIGNIFICANCE. WHEN REPLACING A COMPONENT IDENTIFIED , USE ONLY THE REPLACEMENT PARTS DESIGNATED, OR PARTS WITH THE SAME RATINGS OF RESISTANCE, WATTAGE OR VOLTAGE THAT ARE DESIGNATED IN THE PARTS LIST IN THIS MANUAL. LEAKAGE-CURRENT OR RESISTANCE MEASUREMENTS MUST BE MADE TO DETERMINE THAT EXPOSED PARTS ARE ACCEPTABLY INSULATED FROM THE SUPPLY CIRCUIT BEFORE RETURNING THE PRODUCT TO THE CUSTOMER.

CAUTION : Regular type resistors and capacitors are not listed. To know those values, refer to the schematic diagram. Regular type resistors are less than 1/4W carbon type and 0 ohm chip resistors.

Regular type capacitors are less than 50V and less than 1000 F of Ceramic type and Electrolytic type.
