Clean components mounted in the open of gross contamination as nec
-
essary. We recommend to clean the worst of the dirt on the MIQ mod
-
ule and the area around it each time before opening in order to prevent
gross contamination from entering the open enclosure.
To clean the module, wipe the enclosure surfaces with a damp, lint-free
cloth. If compressed air is available on site, blow off the worst of the dirt
beforehand. Keep the enclosure closed while doing so.
Note
The enclosure and the window of the display are made of plastic.
Therefore, avoid any contact with acetone or similar cleaning agents.
Any splashes must be wiped off immediately.
