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

(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.

3. AC BIAS FREQUENCY ADJUSTMENT

(1) Connect counter to T201(BS). (2) R/P switch in recording state. (3) Adjustment T801 a plastic screw , AC bias frequency : 80 kHz.

4. 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.

5. 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 designated components in which safety can be of special significance.

When replacing a component identified by same ratings of resistance, wattage or voltage that are designated in the parts list in this manual. Leakagecurrent 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.

, use only the replacement parts designated, or parts with the
