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.
