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 technical specifications in manuals to know the maximum sound pressure
levels loudspeakers are capable of producing.
12. Several blow-outs of the fuse (during a short period) are probably a sign of a serious
defect. In this case, the defect needs to be located and repaired immediately. The
blown fuse is to be replaced by a new one having the same specifications.
