6Section 2: PrecautionsWatch For These Symbols The lightning flash with arrowhead symbol withinan equilateral triangle, is intended to alert the userto the presence of uninsulated. “Dangerous Voltage”within the products enclosure that may be of sufficientmagnitude to constitute a risk of electric shock topersons. The exclamation point within an equilateral triangle is intended to alert the user to the presence ofimportant operating and maintenance (Servicing) instructions in the literature accompanying the product.AC Power RequirementsBefore plugging an EON® speaker into an outlet ensure that it is able to providethe appropriate AC power. EON speaker systems have been designed toautomatically detect 115V or 230V AC mains voltage 50/60 Hz.DO NOT UNDER ANY CIRCUMSTANCES OPERATE THE UNIT WITH AN AC POWER SUPPLY LESS THAN100V OR GREATER THAN 240V. DOING SO MAY RESULT IN SERIOUS DAMAGE TO YOUR SPEAKERSYSTEM WHICH WILL NOT BE COVERED BY WARRANTY.A robust AC supply is necessary for maximum performance. If the supply is too weak the bass performance maybe affected and if it sags (drops) too much the system may self-mute to protect itself. As soon as the appropriateAC supply is restored it will continue to operate. Plugging multiple systems into the same outlet and longextension cord runs may affect the AC supply to the systems.CAUTIONIn compliance with safety agency criteria and proper system operation, it is critical that the systeminstaller observe all electrical safety practices at all times and provide proper earth grounding for allAC Power connections.EON® Power Amplifiers - Operating TemperatureThe design of the EON amplifier is such that it is very energy efficient and as a result does not get really hot.In the rare event that it does get too hot it will automatically shut down to protect itself. When its temperaturehas returned to within its operating range it will turn back on. A condition under which this may occur is when thesystem is operated in very high ambient temperatures and the heat sink on the rear of the enclosure is in directsunlight. Always ensure adequate cooling and appropriate shade.Care and MaintenanceWhile your EON speakers are rugged and will provide years of service, some common sense care in handlingwill prevent damage and preserve appearance.• If your speakers will be frequently moved, consider a padded carrying bag.• If your EON speakers have been subjected to prolonged exposure to extreme low temperatures, avoidsubjecting them to heavy mechanical shock and warm the speakers up by playing at a low volume for onehour before playing at loud levels.• Keep the exterior of the speaker enclosure clean. Clean only with a dry cloth.• EON speakers are not intended for fixed installation in outdoor environments. Moisture can damage thespeaker cone and surround, cause corrosion of electrical contacts, and create an electrical shock hazard.Protect your speakers from moisture. Avoid exposing the speakers to direct moisture. Any electricallypowered device can produce dangerous shock hazards when wet or exposed to moisture. Keep speakersout of extended or intense direct sunlight. The driver’s integrity may be affected and finished surfaces will bedegraded by long-term exposure to intense ultra-violet (UV) light.
