Maintenance Features
Cleaning:
Regular cleaning is essential for preventing malfunction and ensuring a long product lifetime.
- Housing: Use a clean, soft, non-abrasive cloth with hot water or mild detergents (without abrasive or oily content). Do not spray directly on the housing.
- Display: Use a clean, soft, non-abrasive cloth (preferably cotton) with a standard glass cleaner (without abrasive or oily content). Do not spray directly on the screen.
- Important: Always switch off the monitor and disconnect from the power supply before cleaning. Do not use chemical solvents, abrasive compounds, or materials, as these can damage the surface or protective coat.
Recycling and Disposal:
The product is not to be disposed of as normal domestic waste. It must be properly recycled or disposed of according to local regulations, as components may contain hazardous substances (e.g., lithium battery, electrolytic capacitor, display). Sonove recommends environmentally sound disposal methods, including reuse or recycling of products and components.
