Selecting fine audio equipment such as the unit you have 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 In-
dustries 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's 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.
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.
