shocks. When using smoke machines, make sure that the device is never exposed to the direct smoke jet
and is installed in a distance of 0.5 meters between smoke machine and device.
The ambient temperature must always be between -5° C and +45° C. Keep away from direct insulation
(particularly in cars) and heaters.
The relative humidity must not exceed 50 % with an ambient temperature of 45° C.
This device must only be operated in an altitude between -20 and 2000 m over NN.
The ambient contamination must never exceed level 1 and must not be conducting, only dry.
Never use the device during thunderstorms. Over voltage could destroy the device. Always disconnect the
device during thunderstorms.
Operate the device only after having familiarized with its functions. Do not permit operation by persons not
qualified for operating the device. Most damages are the result of unprofessional operation!
Never use solvents or aggressive detergents in order to clean the device! Rather use a soft and damp cloth.
Please use the original packaging if the device is to be transported.
Never remove the serial barcode from the device as this would make the guarantee void.
