8b. Cleaning and Disinfecting

The thermometer can be cleaned and an intermediate-level of disinfection can be
achieved using the following method.
CAUTION: Never submerge the thermometer in water or any other liquid
CAUTION: Never use abrasive cleaning agents, thinners or benzene for cleaning
and never immerse the instrument in water or other cleaning liquids.
CAUTION: Never insert a sharp object into the scanner area or any other open sur-
face on the thermometer.
CAUTION: Do not use unapproved cleaning or disinfection agents. Use of these
agents may cause damage to components.
CAUTION: Do not use chemicals other than isopropyl or ethyl alcohol on the lens.
Cleaning the lenses
Never use water to wash the thermometer lens directly.
Slightly moisten a cotton swab or cloth with isopropyl
or ethyl alcohol and gently wipe the surface of the lens.
Wipe from side to side rather than in a circular motion
to avoid getting debris on the center of the sensor.
Avoid touching the lens except when cleaning
is required.
