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 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.
