Using this turntable stylus is easy. First, make sure your turntable is turned off. Gently remove the old stylus if there is one. Then, carefully insert the new stylus into the cartridge. Align it properly and make sure it fits snugly. When using, start your turntable and lower the tonearm gently onto the record. As for maintenance, keep the stylus clean. You can use a soft brush to remove dust after each use. Avoid touching the diamond tip with your fingers as the oils can damage it. Store the stylus in a safe place when not in use to prevent it from getting damaged. If you notice any drop in sound quality, it might be time to check the stylus for wear and tear.
