According to OSHA, any exposure in excess of
these permissible limits could result in some
hearing loss. To ensure against potentially
dangerous exposure to high sound pressure
levels, it is recommended that all persons
exposed to equipment capable of producing
high sound pressure levels use hearing pro-
tectors while the equipment is in operation. Ear plugs or protectors in the
ear canals or over the ears must be worn when operating the equipment
in order to prevent a permanent hearing loss if exposure is in excess of the
limits set forth here.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.

10.
Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way,
such as liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture,
does not operate normally, or has been dropped.
11.
The entire sound system must be designed in compliance with the
current standards and laws regarding electrical systems.
12.
When installing and using this apparatus, keep in mind the
technical specifications indicated in the dedicated section of the
manual.
13.
Exposure to extremely high noise levels may cause permanent
hearing loss. Individuals vary considerably in susceptibility to
noise-induced hearing loss, but nearly everyone will lose some
hearing if exposed to sufficiently intense noise for a period of time.
The U.S. Government’s Occupational Safety and Health
Administration (OSHA) has specified the permissible noise level
exposures shown in the following chart.

Rigging Precautions: When mounting or suspending Mackie
loudspeaker enclosures, it is essential that load ratings, rigging
techniques, and special safety considerations be appropriate
for the installation. Use only the mounting/rigging points on
the loudspeaker enclosure intended for this purpose. The user
must determine the load requirements, dynamic loading, and any
other contributing factors affecting the loudspeaker installation.
The user must determine the proper safety factor for specific
applications and the required load rating of the connection
to structure. Comply with all applicable federal, state, and local
regulations.
Mackie strongly recommends the following rigging system practices:
Documentation: Thoroughly document the mounting/rigging design with
detailed drawings and parts lists.
Analysis: Have a licensed structural engineer or other qualified profes-
sional review and approve the mounting/rigging design before its
implementation.
Installation: Use personnel experienced and qualified for mounting/rigging
loudspeakers in accordance with and in compliance with all federal,
state and local regulations.
DANGER: Loudspeakers should be mounted or suspended only by persons
with knowledge of the proper hardware and rigging techniques. When
stacking or pole-mounting loudspeakers, be sure that they are stabilized
and secured from falling over or being accidentally pushed over. Failure to
follow these precautions may result in damage to the equipment, personal
injury, or death.
