Cleaning
The probe is the most delicate part of the thermometer. Use it with care when cleaning the lens to
avoid damage.
If the device is accidentally used without a probe cover, clean the probe as follows:
1. After the measurement, use the cotton swab moistened with alcohol (70% concentration) to
clean the lens (on the inside of the probe).
2. Allow the probe to fully dry for at least one minute.
