Using the Audio - Technica AT - LP10 Universal Headshell is simple. First, take out the headshell and the included installation screws and plastic washers from the package. When installing, carefully place the 4 - pin turntable cartridge into the headshell. Use the elongated through holes to adjust the cartridge's position and overhang according to your preference. Then, use the provided screws to secure the cartridge. The slip - resistant finger lift helps you place the stylus on the record smoothly. As for maintenance, keep the headshell away from dust and moisture. You can use a soft, dry cloth to gently wipe the aluminum body. If you notice any issues with the sound quality, check the connection of the lead wires. Avoid dropping or hitting the headshell, as it's made of lightweight materials and can be damaged easily.
