Using this turntable stylus is easy. Just carefully install it on your Onkyo DN56, OC56, PL33, or Radiant 45 turntable following the manufacturer's instructions. When using, make sure your turntable is on a stable surface to avoid vibrations. As for maintenance, keep the stylus clean. You can use a stylus brush to gently remove dust and debris after each use. Avoid touching the diamond tip with your fingers as the oils can damage it. Also, store the stylus in a safe place when not in use to prevent any accidental damage. If you notice a decline in sound quality, it might be time to replace the stylus.
