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 equip

ment 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 blar

ing or distortion-and, most importantly, without affecting your sen
sitive 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 dam

age or loss in the future. After all, we want you listening for a life

time.

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.
