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.
