DEAR JENSEN® 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 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.
Customer's Record:
The serial number of this product is found on its bottom. You should note the serial
number of this unit in the space provided as a permanent record of your purchase to
aid in identification in the event of theft of loss.
