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 product and cart
combination should be moved with
care. Quick stops, excessive force, and
uneven surfaces 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 recom-
mended by the manufacturer.

8. Ventilation: 

The product should be situated so

that its location 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 cabinet 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 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.

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