Guidelines
•
Use only a dry, soft, lint-free cloth to clean the front screen.
•
Do not use a spray bottle to apply water or any other solutions onto any
surface of the instrument as the liquid may damage internal components.
•
The use of detergents or isopropyl alcohol as cleaning solvents is not
recommended as they may temporarily alter the hydrophobic nature of the
sample surfaces.
