Do not remove cover:  Operate the console with its covers correctly fitted. Disconnect mains 
power by unplugging the power cord if the cover needs to be removed for 
setting internal options. Refer this work to competent technical personnel 
only. 
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 supply 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 tamper 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 vibration. 
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.
