Selecting fine audio equipment such as the unit youʼve just purchased is only the start of your 
musical enjoyment. Now itʼs time to consider how you can maximize the fun and excitement your 
equipment  offers.  VocoPro  and  the  Electronic  Industries  Associationʼs  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  Associationʼs  Consumer  Electronics  Group  recommend  you  avoid 
prolonged exposure to excessive noise. This list of sound levels is included for your protection.
