The cover consists of two parts, both of which can be removed. You do not need tools to
remove the covers.
1. Open the USB connector cover.
2. Remove the lower part of the control panel cover.
3. Remove the upper part of the cover.
Reinstall the covers in the reverse order.

Cleaning the control panel

Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could scratch
the display window.

Cleaning the connectors

(panel front side). Clean outside/around the connectors using suitable cleaning solution (for
example, Isopropyl Alcohol (IPA) solution). Do not use the cleaning solution to clean inside
the connectors.
