  3. Tonearm Balance and Tracking Force:
    • Attach the head shell with the cartridge to the tonearm.
    • Mount the balance weight onto the rear of the tonearm.
    • Adjust the balance weight until the tonearm is perfectly level (floating freely).
    • Set the tracking force ring to "0" while the tonearm is balanced.
    • Rotate the balance weight to apply the recommended tracking force for your cartridge (typically 0-4g, as per the turntable's adjustment range).
  4. એન્ટી-સ્કેટિંગ એડજસ્ટમેન્ટ: Set the anti-skating dial to match the tracking force you applied. This helps prevent the stylus from skipping inwards.
