Section 2: Precautions
Watch For These Symbols
The lightning flash with arrowhead symbol within
an equilateral triangle, is intended to alert the user
to the presence of uninsulated. “Dangerous Voltage”
within the products enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to
persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (Servicing) instructions in the literature accompanying the product.
AC Power Requirements
Before plugging an EON
®
speaker into an outlet ensure that it is able to provide
the appropriate AC power. EON speaker systems have been designed to
automatically detect 115V or 230V AC mains voltage 50/60 Hz.
DO NOT UNDER ANY CIRCUMSTANCES OPERATE THE UNIT WITH AN AC POWER SUPPLY LESS THAN
100V OR GREATER THAN 240V. DOING SO MAY RESULT IN SERIOUS DAMAGE TO YOUR SPEAKER
SYSTEM 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 may
be affected and if it sags (drops) too much the system may self-mute to protect itself. As soon as the appropriate
AC supply is restored it will continue to operate. Plugging multiple systems into the same outlet and long
extension cord runs may affect the AC supply to the systems.
CAUTION
In compliance with safety agency criteria and proper system operation, it is critical that the system
installer observe all electrical safety practices at all times and provide proper earth grounding for all
AC Power connections.

Power Amplifiers - Operating Temperature
The 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 temperature
has returned to within its operating range it will turn back on. A condition under which this may occur is when the
system is operated in very high ambient temperatures and the heat sink on the rear of the enclosure is in direct
sunlight. Always ensure adequate cooling and appropriate shade.
Care and Maintenance
While your EON speakers are rugged and will provide years of service, some common sense care in handling
will 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, avoid
subjecting them to heavy mechanical shock and warm the speakers up by playing at a low volume for one
hour 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 the
speaker 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 electrically
powered device can produce dangerous shock hazards when wet or exposed to moisture. Keep speakers
out of extended or intense direct sunlight. The driver’s integrity may be affected and finished surfaces will be
degraded by long-term exposure to intense ultra-violet (UV) light.
