     MAINTENANCE

 

 

The unit does not have any internal replaceable components available to the user. Pay  

attention to the ambient temperature in the room where the unit is operating. Excessively high  

temperatures cause faster ageing of the internal components and shorten the fault-free time of  

unit operation. 

In cases where the unit gets dirty do not clean with solvents. For cleaning use warm water with  

small amount of detergent or in the case of more significant contamination ethyl or isopropyl  

alcohol. 

Using any other agents can cause permanent damage to the housing.

Product marked with this symbol should not be placed in municipal waste. Please  

check local regulations for disposal and electronic products.
