5. Caution
5.1 Prevent the detector from falling down from high places or
strenuous vibration.
5.2 DO NOT use sensor tip to touch other objects directly nor block
sensor tip.
5.3 When there is interferential high-concentration gas, detector
may not work normally.
5.4 The detector will only detect gas concentration from the
detection interface. So, for example, when you are on the function
menu, it will not detect.
5.5 The detector should not be stored or used where there are
caustic gases (such as Cl2), or under other rigorous circumstances
(including excessive high and low temperature, high humidity,
electromagnetic field and strong sunlight).
5.6 After long-term use, if there is dust on detector surface, please
clean it lightly with clean soft cloth, instead of caustic solvents or
hard things.
