A Message from the JBL manufacturer 
and the Consumer Electronics Association:

Selecting fine audio equipment, such as the unit you have just purchased, is only the 

start of your musical enjoyment. Now it is time to consider how you can maximize 

the fun and excitement your equipment offers. JBL and the Consumer Electronics 

Association 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 important, without affecting your sensitive hearing. 
Sound can be deceiving. Over time your hearing “comfort level” adapts to higher    

volumes of sound. What sounds “normal” can actually be loud and harmful to your 

hearing. Guard against this by choosing 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, clearly, and without distortion. 

ONCE YOU HAVE ESTABLISHED A COMFORTABLE SOUND LEVEL:

• Do not exceed that level.

Taking a moment to do this now will help to prevent hearing damage or loss 

in the future. After all, we want you listening for a lifetime.
