Care and cleaning
1. The probe is the most delicate part of the thermometer. Use with
care when cleaning the lens to avoid damage.
2. After the measurement, please use the cotton swab with the Alco-
hol (70% concentration) to clean the inside of the probe, including
lens and metal parts.
3. Allow the probe to fully dry for at least 5 minutes.
4. Storage temperature range: It should be stored at room tempera-
ture between -25~+55°C, RH<=95%
5. Keep the unit dry and away from any liquids and direct sunlight.
6. The probe should not be submerged into liquids.
7. Please check the device if damaged once it falls. If you can't make
sure of it, please send the complete device to the nearest retailer
for re-calibration.
8. Holding the thermometer too long may cause a higher ambient
temperature reading of the probe. This could make the body tem-
perature measurement lower than usual. Please try not to touch
the thermometer probe part for avoiding the incorrect reading.
