Listening For A Lifetime
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.  VocoPro  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 a higher volume 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.
• Pay attention to the different levels in various recordings.
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
