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
a[[d
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.
