General cleaning safety precautions

Never use solvents or flammable solutions to clean the workstation.

and then use the cloth on the component.
●
Always unplug the workstation before cleaning the keyboard, mouse, or air vents.

Always disconnect the keyboard before cleaning it.
●
Wear safety glasses equipped with side shields when cleaning the keyboard.

Cleaning the workstation case

●
Follow the safety precautions presented in before cleaning the workstation.
●

After cleaning, always wipe the unit with a clean, lint-free cloth.
