Important Safety Instructions

WARNING:

To reduce the risk of fire or electric shock, do not expose this 

product to rain or moisture.

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 product’s 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 you to the presence of important
operating and maintenance (servicing) instructions in the literature accompanying the product.

1. 

Read Instructions: 

All the safety and operating instructions

should be read before the product is operated.

2. 

Retain Instructions:

The safety and operating instructions

should be retained for future reference.

3. 

Heed Warnings:

All warnings on the product 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 product should not be used near

water—for example, a bathtub, washbowl, kitchen sink, laundry
tub, in a wet basement, or near a swimming pool, etc.

6. 

Carts and Stands:

The product should be used only with a

cart or stand that is recommended by the manufacturer. A prod-

uct and cart combination should be moved with
care. Quick stops, excessive force, and uneven sur-
faces may cause the product and cart combination
to overturn.

7. 

Wall- or Ceiling-Mounting:

The product should be mounted

to a wall or ceiling only as recommended by the manufacturer.

8. 

Ventilation:

The product should be situated so that its loca-

tion or position does not interfere with its proper functioning.
For example, the product should not be situated on a bed, sofa,
rug, or similar surface that may obstruct the heat sink surfaces;
nor placed in a built-in installation, such as a bookcase or cabi-
net that may impede the flow of air near the heat sink surfaces.

9. 

Heat: 

The product should be situated away from heat sources

such as radiators, stoves, or other products that produce heat.

10. 

Power Sources:

The product should be connected to a

power supply only of the type described in the operating
instructions or as marked on the product.

11. 

Grounding or Polarization:

This product may be equipped

with a polarized alternating-current line plug (a plug having one
blade wider than the other). This plug will fit into the power out-
let 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 polar-
ized plug.

12. 

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. Pay particular attention to
cords and plugs, convenience receptacles, and the point where
they exit from the product.

13. 

Cleaning: 

Unplug this product from the wall outlet before

cleaning. Do not use liquid cleaners or aerosol cleaners. Use a
damp cloth for cleaning.

14. 

Nonuse Periods:

The power cord should be unplugged

from the outlet when left unused for long periods of time.

15. 

Object and Liquid Entry:

Care should be taken so that

objects do not fall into and liquids are not spilled into the inside
of the product.

16. 

Lightning:

For added protection for this product during a

lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the wall outlet and discon-
nect the cable system. This will prevent damage to the product
due to lightning and power line surges.

17. 

Damage Requiring Service:

The product should be serviced

if any of the following events occur:

A. The power supply cord or the plug has been damaged;

B. Objects have fallen or liquid has been spilled into the

product;

C. The product has been exposed to rain;

D. The product does not appear to operate normally or 

exhibits a marked change in performance; or

E. The product has been dropped or the enclosure damaged.

18. 

Servicing:

The user should not attempt to service the prod-

uct beyond what is described in the operating instructions. For
all other servicing, consult your dealer or contact Boston
Acoustics.
