4.3. MAINTENANCE

The unit does not have any internal replaceable or adjustable 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.
