• The device must be reliably grounded to ensure anti-interference performance and operator safety.
• Do not touch the screen with sharp tools, hard objects or wet hands to prevent screen scratching, cracking and electric leakage risks.
• Do not disassemble or modify the internal structure of the HMI without authorization; otherwise, the warranty will be invalid.
• Avoid strong vibration, impact, and long-term direct sunlight irradiation during operation.
