12. 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 the unit's operation.
When the unit gets dirt, do not clean with solvents. For cleaning, just use warm water with a small
amount of detergent or in the case of more significant contamination ethyl or isopropyl alcohol.
