IMPORTANT SAFETY PRECAUTIONS
1. READ INSTRUCTIONS – All the safety and
operating instructions should be read before this
product is operated.
2. RETAIN INSTRUCTIONS – The safety and
operating instructions should be retained for future
reference.
3. HEED WARNINGS – All warnings on the
amplifier and in the operating instructions should be
adhered to.
4. FOLLOW INSTRUCTIONS – All operating and
use instructions should be followed.
5. WATER AND MOISTURE – The speaker system
should not be used near water - for example, a
bathtub, washbowl, kitchen sink, laundry tub, wet
basement, or near a swimming pool, and the like.
6. CARTS AND STANDS – The speaker system
should be used only with a cart or stand that is recom-
mended by the manufacturer.
A speaker and cart combination
should be moved with care. Quick
stops, excessive force, and uneven
surfaces may cause the speaker
and cart combination to overturn.
7. WALL OR CEILING MOUNTING – The product
should never be mounted to a wall or ceiling.
8. HEAT – The amplifier on the back of the ACTPRO
system should be situated away from heat sources such
as radiators, heat registers, stoves, or other sources
(including amplifiers) that produce heat.
9. POWER SOURCES – This product should be
operated only from the type of power source indicated
on the rating label. If you are not sure of the type
of power supply to your home, consult your product
dealer or local power company.
10. GROUNDING OR POLARIZATION – This
product may be equipped with a polarized alternation-
current line plug (a plug having one blade wider than
the other). This plug will fit into the power outlet only
one way. This is a safety feature. If you are unable to
insert the plug fully into the outlet, try reversing the
plug. If the plug should still fail to fit, contact your
electrician to replace your obsolete outlet. Do not
defeat the safety purpose of the polarized plug.
11. POWER-CORD PROTECTION – Power-supply
cords should be routed so that they are not likely to be
walked on or pinched by items placed upon or against
them, paying particular attention to the cord in cor-
respondence of plugs, convenience receptacles, and the
point where they exit from the amplifier.
12. CLEANING – The speaker and amplifier should
be cleaned only as recommended by the manufacturer.
Clean by wiping with a cloth slightly damp with water.
Avoid getting water inside the speaker or amplifier.

The lightning flash with arrowhead symbol within the equilateral triangle is intended to alert the use to the
presence of un-insulated "dangerous voltage" within the product's enclosure that may be of sufficient
magnitude to constitute a risk of electric shock.
The exclamation point within the equilateral triangle is intended to alert the user to the presence of important
operation and maintenance (servicing) instructions in the literature accompanying this appliance.
To prevent electric shock, do not use a polarized plug with an extension cord, receptacle or other outlet unless the blades
