periodic cleaning of the unit when needed:
 Once a unit is removed from service, clean the exterior with a mild
solution of detergent and water. Apply the solution onto a soft
cloth, not directly to the surface of the unit. To prevent damage to
materials, do not use aromatic hydrocarbons or chlorinated
solvents for cleaning.

Low

in and around components on the printed circuit boards.
