1. SAFETY INSTRUCTIONS

1.  Read these instructions. 
2.  Keep these instructions.
3.  Heed all warnings.
4.  Follow all instructions.
5.  Do not use this apparatus near water.
6.  Clean only with a dry cloth.
7.  Do not block any ventilation openings. Install in accordance with the 

manufacturer’s instructions.

8.  Do not install near any heat sources such as radiators, heat registers, 

stoves, or other apparatus (including amplifiers) that produce heat.

9.  Only use attachments/accessories specified by the manufacturer.
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 high sound levels can cause permanent hearing loss. The 

sound pressure level which leads to hearing loss varies considerably 

from one person to another, and depends on the duration 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 

specifications provided in the instruction manual to know the maximum 

sound pressure (SPL) the loudspeaker is capable of producing.

14.  Rigging Precautions: When mounting or suspending EAW Commercial 

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 design factor for specific applications and the required load rating 

of the connection to structure. Comply with all applicable federal, state, 

and local regulations.

 

 EAW Commercial 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 

professional 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. Failure to follow these precautions may result in damage 

to the equipment, personal injury, or death.

WARNING!

 This equipment has been designed 

to be installed by qualified professionals only! 

There are many factors to be considered when 

installing professional sound reinforcement systems, 

including mechanical and electrical considerations, as well 

as acoustic coverage and performance. EAW Commercial 

strongly recommends that this equipment be installed only by a 

professional sound installer or contractor.
