WE WANT YOU LISTENING
FOR A LIFETIME
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 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.
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.
