1.4.Foreign Bodies and Liquids — Be careful not to allow any foreign bodies or liquids to get into this EAW Commercial product.
1.5.Servicing — The user should never attempt to make any repairs on this EAW Commercial product unless otherwise indicated in the instruction manual. All repairs should be made by qualified service technicians.
1.6.Installation — Do not install this EAW Commercial product in any way that is not provided for in the instruction manual.
1.7.Respect the Safety Standards — The entire sound system must be designed in compliance with the current standards and laws regarding electrical systems.
1.8.Specifications — When installing and using this EAW Commercial product, keep in mind the technical specifications indicated in the dedicated section of the manual.
1.9.Accessories — Install and use this EAW Commercial product only with the accessories specified by the manufacturer or supplied with the product.
1.10.Hearing Loss — 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 speaker is capable of producing.
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.

3. INTRODUCTION
The SMS4 and SMS4W are a compact two-way loudspeaker system designed for constantvoltage. The 5” (130 mm) carbon fiber woofer, in combination with a 0.5” (13 mm) mylar dome tweeter mounted on a 110° x 110° constant directivity horn, provide natural, smooth sound reproduction, ideal for use in business music systems and indoor/outdoor background music applications. The passive crossover is designed to reduce heat dissipation and optimize the power response of the loudspeaker. Connections are made to recessed, color – coded spring-loaded terminals. The enclosure is constructed of high-density plastic, with M6 threaded inserts for use with the optional mounting hardware, and includes a protective perforated steel grille.
