10. Cleaning and Storage
Use an alcohol swab or cotton swab moistened with alcohol (70%
Isopropyl) to clean the thermometer casing and the measuring
probe. Ensure that no liquid enters the interior of the thermometer.
Never use abrasive cleaning agents, thinners or benzene for clean-
ing and never immerse the instrument in water or other
cleaning liquids. Take care not to scratch the surface of the LCD.
Remove the battery from the instrument if it is not required for
extended periods of time in order to avoid damage to the ther-
mometer resulting from a leaking battery.
