GENERAL OPERATING PRECAUTIONS
• Do not obstruct the ventilation grilles of the unit. Situate this product far from any heat sources and always ensure
adequate air circulation around the ventilation grilles.
• Do not overload this product for extended periods of time.
• Never force the control elements (keys, knobs, etc. ).
• Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external parts of this product.
(wall, ceiling, structure, etc.), and the components used for attachment (screw anchors, screws, brackets not supplied by RCF
etc.), which must guarantee the security of the system / installation over time, also considering, for example, the mechanical
vibrations normally generated by transducers.
To prevent the risk of falling equipment, do not stack multiple units of this product unless this possibility is specified in the user
manual.
8.
RCF S.p.A. strongly recommends this product is only installed by professional qualified installers (or specialised firms) who
can ensure correct installation and certify it according to the regulations in force.
The entire audio system must comply with the current standards and regulations regarding electrical systems.
9.
Supports and trolleys.
The equipment should be only used on trolleys or supports, where necessary, that are recommended by the manufacturer. The
equipment / support / trolley assembly must be moved with extreme caution. Sudden stops, excessive pushing force and uneven
floors may cause the assembly to overturn.
10.
There are numerous mechanical and electrical factors to be considered when installing a professional audio system (in
addition to those which are strictly acoustic, such as sound pressure, angles of coverage, frequency response, etc.).
11.
Hearing loss.
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is
different from person to person and depends on the duration of exposure. To prevent potentially dangerous exposure to high
levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices. When a transducer
capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or protective earphones. See
the manual technical specifications to know the maximum sound pressure level.
To prevent the occurrence of noise on line signal cables, use screened cables only and avoid putting them close to:
- Equipment that produces high-intensity electromagnetic fields.
- Power cables
- Loudspeaker lines.
