Arcade operators face unique challenges when maintaining machine performance in areas with high electromagnetic interference (EMI). To combat EMI, they employ several strategies, including proper grounding, EMI shielding, and regular maintenance. High-quality shielded cables and ferrite cores are often used to reduce signal disruption. Additionally, operators may relocate machines away from strong EMI sources or install Faraday cages for extreme cases. Routine diagnostics and firmware updates also help ensure stable performance. By combining these methods, arcade operators can minimize downtime and deliver a seamless gaming experience even in electromagnetically noisy environments.
