Security measures

Protect the thermometer from overheating, undercooling and moisture penetration
inside the thermometer. Do not heat the thermometer over 70⁰C .
The power level of the signal radiated by the thermometer does not exceed the
established norms. But the thermometer may be sensitive to electromagnetic
interference generated by other devices. It is therefore recommended to avoid working
in close proximity to the thermometer electronic devices that generate strong
electromagnetic field.
Do not attempt to repair the thermometer by yourself. This can result in inaccurate
readings or thermometer failure.
If the thermometer is not used for a long time the battery should be removed and
stored separately.
Observe polarity when replacing the battery.
Lithium battery and the device itself should be disposed off in accordance with local
regulations and not be thrown away with household waste.
