We Want You Listening For A Lifetime

_mV.

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.

Selecting fine audio equipment such as the unit you've just

Decibel

purchased is only the start of your musical enjoyment. Now it' s time

Level

to consider how you can maximize the fun and excitement your

equipment offers. This manufacturer and the Electronic Industries

Association' s Consu met 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. Alter all, we want you listening for a

lifetime.
