For Panasonic's six-disc movement, you can perform timing calibration according to the following steps: 1. Open the cover of the six-piece movement and find the timing calibration hole next to the movement. Usually, there may be a small hole or mark on the timing calibration hole to identify the position. 2. Move the stylus in the movement to the center of the turntable, and then turn the speed adjustment knob to turn the stylus to the starting position of the singing arm. There is usually an indicator light at this position to indicate whether the stylus has reached the correct position. 3. Use a screwdriver and other tools to gently turn the fine-tuning screw on the timing calibration hole until the stylus accurately falls on the CD and keeps rotating steadily. 4. When turning the fine-tuning screw on the timing calibration hole, you should be careful and slow, just adjust it slightly. 5. Put down the singing arm, let the movement run for a period of time, and then adjust the fine-tuning screw on the timing calibration hole again to ensure that the disc speed remains stable. Through the above operations, the timing calibration of Panasonic six-disc movement can be carried out. It should be noted that this is a complicated operation. If you are not sure how to operate, it is recommended to consult professional maintenance engineers or technical support personnel for help. In addition, the timing calibration of the movement needs to be carried out regularly to ensure the stability and normal operation of the equipment.
