10. CLEANING
CLEANING THE WAVEGUIDE: the thermometer waveguide (g. 1) is very delicate.
Therefore, when the thermometer is not being used, we recommend that you always

sensor at its base, use a cotton swab that has been slightly dampened with alcohol.
Remove all dirt and make certain that nothing accumulates at the bottom of the wave

guide where the sensor is located. Do not use any other objects or liquids as the sur-
face of the sensor could easily be scratched or damaged. Never let any excess liquid
penetrate into the waveguide and sensor.
CLEANING THE THERMOMETER BODY: use a soft cloth dampened with soap and
water and possibly re-wipe with a sodium hypochlorite disinfectant.
DO NOT USE the thermometer for at least 30 minutes after cleaning.
