Safety Instructions
Clean
When cleaning the monitor case or the surface of the TFT-LCD, wipe with a
slightly moistened, soft fabric.
Do not spray water or detergent directly on the monitor.
This may cause damage, electric shock or a fire.
Use the recommended detergent with a smooth cloth.
If the connector between the plug and the pin is dusty or dirty, clean
it properly with a dry cloth.
A dirty connector can cause an electric shock or fire.
