PRECAUTIONS
MOUNTING INSTRUCTIONS
• When opening the stations ESD precautions must be observed. • The stations may be opened by authorised service engineers only.
• Do not expose the station to extreme temperature (under -40° C or above +90° C / –40°F to 194°F). • Please take care that the front panel of the ET 570/ET 571 is attached to the mounting plate without margin. Otherwise an “acoustic short circuit“ occurs, which can considerably influence the sound of the ET 570/ET 571.
