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.
