● Protective measures: In industrial or harsh environments, consider installing protective films, covers, or waterproof casings to enhance the durability and resistance to dirt of the touch screen.
● Avoid liquid contact: Prevent liquids from splashing onto the touch screen to avoid damaging the electronic components. Avoid placing liquid containers directly on the touch screen during use.
● Electrostatic discharge (ESD) precautions: For touch screens sensitive to static electricity, take appropriate ESD measures such as using anti-static cleaners and grounding devices.
● Follow operating guidelines: Adhere to the operation guidelines and user manuals provided for the touch product. Use and operate the touch features correctly to avoid accidental actions or unnecessary damage.
