Read instructions:  Retain  these  safety  and  operating  instructions  for  future  reference.  Adhere  to  all  warnings  printed 
here and on the console. Follow the operating instructions printed in this User Guide. 
Do not remove cover:  Operate the console with its covers correctly fitted. 
Power sources:   Connect the console to a mains power unit only of the type described in this User Guide and marked 
on the rear panel.  Use the power cord with sealed mains plug appropriate for your local mains sup-
ply as provided with the console. If the provided plug does not fit into your outlet consult your service 
agent for assistance. 
Power cord routing:  Route the power cord so that it is not likely to be walked on, stretched or pinched by items placed 
upon or against it. 
Grounding:  Do not defeat the grounding and polarisation means of the power cord plug. Do not remove or tam-
per with the ground connection in the power cord. 
Water and moisture:   To reduce the risk of fire or electric shock do not expose the console to rain or moisture or use it in 
damp or wet conditions. Do not place containers of liquids on it which might spill into any openings. 
Ventilation:   Do not obstruct the ventilation slots or position the console where the air flow required for ventilation 
is impeded. If the console is to be operated in a rack unit or flightcase ensure that it is constructed to 
allow adequate ventilation. 
Heat and vibration:  Do not locate the console in a place subject to excessive heat or direct sunlight as this could be a fire 
hazard. Locate the console away from any equipment which produces heat or causes excessive vi-
bration. 
Servicing:    Switch off the equipment and unplug the power cord immediately if it is exposed to moisture, spilled 
liquid, objects fallen into the openings, the power cord or plug become damaged, during lightening 
storms, or if smoke, odour or noise is noticed. Refer servicing to qualified technical personnel only. 
Installation:    Install the console in accordance with the instructions printed in this User Guide. Do not connect the 
output  of  power  amplifiers  directly  to  the  console.    Use  audio  connectors  and  plugs  only  for  their 
intended purpose.
