CARE AND MAINTENANCE

 

Avoid placing the units in areas prone to vibration and shock as these may cause damage. 

 

Avoid areas where the units can be exposed to sudden changes in temperature, i.e. direct 
sunlight, extreme cold and wet/moist conditions as these will lead to rapid changes which 
reduces the accuracy of readings. 

 

When cleaning the LCD and casing, use a soft damp cloth only. Do not use solvents or 
scouring agents. 

 

Do not submerge the units into water. 

 

Immediately remove all low powered batteries to avoid leakage and damage. Replace only 
with new batteries of the recommended size. 

 

Do not make any repairs to the units. Please return it to the original point of purchase. 
Opening and tampering with the units may invalidate the warranty.
