Dear Customer:
Selecting fine audio and video 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.
This list of sound levels is included for your protection.
