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 ForA 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.
