• The relative humidity should be less than 80%; moisture should not
condense on the instrument.
• Leave at least a 15 cm clearance at the top and on all sides for air
circulation, to avoid overheating of electrical parts.

accessories clean and dry at all times. Immediately remove
splashes or spilt materials on or in the instrument.
