8.

Do not install near any heat sources such as radiators, heat registers, stoves, or other 
apparatus (including amplifiers) that produce heat.

9.

Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized 
plug has two blades with one wider than the other. A grounding type plug has two blades
and a third grounding prong. The wide blade or the third prong is provided for  your 
safety. If the provided plug does not fit into your outlet, consult an electrician for 
replacement of the obsolete outlet.

10.  The power plug at the wall must remain accessible to be able to disconnect power from 

the apparatus.

11. Protect the power cord from being walked on or pinched particularly at plugs, convenience

receptacles, and the point where they exit from the apparatus.

12. Only use attachments/accessories specified by the manufacturer.
13. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or 

sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus
combination to avoid injury from tip-over.

14. Unplug this apparatus during lightning storms or when unused for long periods of time.
15. Refer all servicing to qualified service personnel. Servicing is required when the 

apparatus has been damaged in any way, such as power-supply cord or plug is damaged,
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.

16. This apparatus shall not be exposed to dripping or splashing, and no object filled with 

liquid, such as vases, shall be placed on the apparatus.

17. This apparatus has been designed with Class-I construction and must be connected to 

a mains socket outlet with a protective earthing connection (the third grounding prong).

18. This apparatus does not exceed the Class A/Class B (whichever is applicable) limits for 

radio noise emissions from digital apparatus as set out in the radio interference 
regulations of the Canadian Department of Communications.

ATTENTION: -Le présent appareil numérique n'émet pas de bruits radioélectriques dépassant las
limites applicables aux appareils numériques de class A/de class B (selon le cas) prescrites dans le
règlement sur le brouillage radioélectrique édicté par les ministere des communications du Canada.

19. If the loudspeaker is exposed to changes in temperature and humidity, internal condensation

may develop. If powered up with such condensation, electronic failure could result. When 
exposed to environmental changes, allow the loudspeaker at least 30 minutes to 
acclimate to a new temperature before connecting to the ac mains and operating. 

20. EAW loudspeakers can produce sound levels capable of causing permanent hearing damage

from prolonged exposure. The higher the sound level, the less exposure needed to cause 
such damage. Avoid prolonged exposure to the high sound levels from the loudspeaker.

DANGER: There is danger of explosion if battery is incorrectly replaced. Replace only with the
same or equivalent type. This applies to any loudspeakers with a battery.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS
APPLIANCE TO RAIN OR MOISTURE. DO NOT EXPOSE THE APPARATUS TO DRIPPING OR
SPLASHING AND DO NOT PLACE OBJECTS FILLED WITH LIQUIDS, SUCH AS DRINKS, ON
THE APPARATUS.

CAUTION:

This product is energized as long as it is connected to the AC mains supply.

CAUTION:

Allow at least six inches of free space all around the amplifier heat sink for

sufficient ventilation.
