Using this stylus is easy. First, make sure your turntable is turned off. Then, carefully remove the old stylus if there is one. Take the new D1240SR stylus and gently place it in the appropriate slot on the turntable. Once it's in place, you can turn on the turntable and start enjoying your music. As for maintenance, keep the stylus clean. You can use a soft brush to gently remove any dust or debris. When not in use, cover the turntable to protect the stylus from getting dirty. Also, be careful when handling the stylus to avoid any damage. Don't touch the diamond tip with your fingers as it can affect the sound quality. If you notice any issues with the sound, it might be time to check the stylus for wear and tear.
