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.
