Using this turntable stylus is quite easy. First, make sure your turntable is turned off. Then, carefully remove the old stylus if there is one. Gently insert the new Stanfield D326SR stylus into the appropriate slot on the turntable. When you're done, turn on the turntable and start enjoying your music. As for precautions, always handle the stylus with clean hands to avoid getting dirt or oil on it. Also, don't apply too much pressure when installing or using it. For maintenance, clean the stylus regularly with a soft brush. This will keep it in good condition and ensure great sound quality for a long time.
