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 are provided for your safety. If the 
provided plug does not fit into your outlet, consult an electrician for 
replacement of the obsolete outlet.

10) Protect the power cord from being walked on or pinched particularly 

at plugs, convenience receptacles, and the point where they exit from 
the apparatus.

11) Only use attachments/accessories specified by the manufacturer.

12) 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.

13) Unplug this apparatus during lightning storms or when unused for 

long periods of time.

14) 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.

Selecting fine audio equipment such as the unit 
you’ve just purchased is only the start of your 
musical enjoyment. Now it’s time to consider 
how you can maximize the fun and excitement 
your equipment offers. This manufacturer and 
the Electronic Industries Association’s 
Consumer Electronics Group want you to get 
the most out of your equipment by playing it at a 
safe level. One that lets the sound come 
through loud and clear without annoying blaring 
or distortion—and, most importantly, without 
affecting your sensitive hearing.

We recommend that you avoid prolonged 
exposure to excessive noise.

Sound can be deceiving. Over time your 
hearing “comfort level” adapts to higher 
volumes of sound. So what sounds “normal” 
can actually be loud and harmful to your 
hearing.

Guard against this by setting your equipment at 
a safe level BEFORE your hearing adapts.

To establish a safe level:
≥ Start your volume control at a low setting.
≥ Slowly increase the sound until you can hear 

it comfortably and clearly, and without 
distortion.

Once you have established a comfortable 
sound level:
≥ Set the dial and leave it there.

Taking a minute to do this now will help to 
prevent hearing damage or loss in the future. 
After all, we want you listening for a lifetime.

The model number and serial number of this product can be found

reference.
