1. Features and Functions

Dear Customer!

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 equipmentat a safe level BEFORE your hearing adapts.

To establish a safe level:

® Start your volume control at a low setting.

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 Jate, 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.
