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:
clearly,and without distortion.
Once you have established a comfortable sound level:
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 cover. 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.
Start your volume control at a low setting.
Slowly increase the sound until you can hear it comfortably and
Set the dial and leave it there.
