Listening caution
Selecting fine audio equipment such as the unit you’ve just pur-
chased 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.
We recommend that you avoid prolonged exposure to excessive
noise.
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.
