Arcade operators face significant challenges when maintaining gaming machines in environments with high electromagnetic interference (EMI), such as industrial zones or near heavy electrical equipment. EMI can cause graphical glitches, input errors, random resets, and overall system instability in arcade cabinets. To combat these issues, operators employ multiple strategic approaches. First, they prioritize physical shielding by installing EMI-resistant cabinets or adding conductive coatings and metallic meshes to existing units. Second, they utilize ferrite chokes on power and video cables to suppress high-frequency noise. Third, operators often replace standard internal components with industrial-grade, EMI-hardened parts designed to withstand electromagnetic pollution. Regular maintenance includes diagnostic testing with EMI meters to identify interference patterns and preemptively address vulnerabilities. Environmental controls like dedicated power conditioners and proper grounding systems form another critical layer of protection. Additionally, strategic machine placement—avoiding proximity to large motors, transformers, or RF transmitters—helps minimize exposure. Through these combined technical measures, arcade operators ensure reliable machine operation and consistent player experience despite electromagnetic challenges.
