of exposure. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has
established the maximum sound pressure levels that can be with stood without causing damage,
which are shown in the table below. According to the OSHA regulations, any exposure over the
maximum limits indicated in the table can reduce the hearing capacity of a person. To prevent
potentially dangerous exposure to high sound pressure levels, anyone subjected to such levels
must use suitable protection. When a EAW Commercial product capable of producing high sound
levels is being used, it is therefore necessary to wear ear plugs or protective earphones when
the limits shown in the table are exceeded. Consult the specifi cations provided in the instruction
manual to know the maximum sound pressure (SPL) the loudspeaker is capable of producing.

Mounting Precautions
The mounting bracket provided can be used for wall mounting the loudspeaker.
WARNING: Installation should only be done by an experienced technician.
Improper installation may result in damage to the equipment, injury or death. Make
sure that the loudspeaker is installed in a stable and secure way in order to avoid any
conditions that may be dangerous for persons or structures:
• Check to make sure that the support surface (e.g., wall, etc.) has the necessary
mechanical characteristics to support the weight of the loudspeaker without the
danger of it falling.
• Always use support elements suitable for the material of the wall that will support
the loudspeaker (e.g., screw anchors for bricks, screw anchors for cement, etc.). Due
to various construction methods and materials used today, the hardware for securing
the bracket to the mounting surface is not supplied. Consult a building professional
for the proper mounting hardware before mounting the bracket.
• Before mounting the loudspeaker, carefully check all the components to be used to
make sure there is no damage, deformation, corrosion and/or missing or damaged
parts that could reduce the safety of the installation.
• Consult a professional rigger or structural engineer prior to mounting loudspeakers
from a structure not intended for that use. Always know the working load limit of the
structure supporting the loudspeaker. Always make sure that the rigging hardware
minimum rating is at least fi ve times the actual load.
• Avoid installing the loudspeaker in places exposed to harsh weather conditions.
