Using this turntable stylus is easy. First, make sure your turntable is turned off. Then, gently remove the old stylus if there is one. Align the new stylus carefully with the cartridge and insert it firmly. When using the turntable, place the record gently on the platter and lower the tonearm with the stylus onto the record. As for maintenance, keep the stylus clean. You can use a stylus brush to remove dust after each use. Avoid touching the diamond tip with your fingers as the oils can damage it. Also, store the turntable in a dry and clean place to prevent any potential damage to the stylus. If you notice a decrease in sound quality, it might be time to replace the stylus.
