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.

Used wisely, your new sound equipment will provide a

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.
