General Precautions
Damage : To prevent damage to the controls and cosmetics avoid placing heavy
objects on the control surface, scratching the surface with sharp objects, or
subjecting the console to rough handling and vibration.
Environment : Protect from excessive dirt, dust, heat and vibration when operating and
storing. Avoid tobacco ash, smoke, drinks spillage, and exposure to rain and
moisture. If the console becomes wet, switch off and remove mains power
immediately. Allow to dry out thoroughly before using again.
Radiation : To avoid induced noise and interference pickup do not operate the console
close to strong sources of electromagnetic radiation such as power supplies,
video monitors, lighting cables and dimmers.
Cleaning : Avoid the use of chemicals, abrasives or solvents. The control panel is best
cleaned with a soft brush and dry lint-free cloth. Stubborn marks can be
removed using a cloth dampened with isopropyl alcohol. Do not leave
marking tape stuck to the console for long periods of time as the adhesive
can degrade and leave a sticky residue. The faders, switches and
potentiometers are lubricated for life. The use of electrical lubricants on these
parts is not recommended. Refer to the power unit user guide for instructions
on cleaning its ventilation filters.
Transporting : The console should be transported in the original packing or purpose built
foam lined flightcase. Protect the control surface from damage during transit.
The console is a large and heavy item. To avoid injury ensure adequate man
power and precaution when lifting or moving the console.
