Dear Customer
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.
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.
We Want You Listening For A Lifetime
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage
from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries
Association’s Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise.
