DEAR CUSTOMER: TO ESTABLISH A SAFE LEVEL:
• Set your volume control at a low setting.
BE SURE TO OBSERVE THE FOLLOWING GUIDELINES.
Once you have established a comfortable
sound level:
USE YOUR HEAD
WHEN YOU USE YOUR HEADSET
• Do not turn up the volume so high
that you can't hear what's around you.
• You should use caution or temporarily
discontinue use in potentially
hazardous situations.
• Do not use headphones while
operating a motorized vehicle;
it may create a traffic hazard and is
illegal in many areas.
Set the dial and leave it there.
Taking a minute to do this now will help
preserve hearing.
• Slowly increase the sound until you can hear it comfortably and
clearly, without distortion.
Remember ....

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. This
manufacturer and the Consumer Electronics Association® (CEA) want
you to get the most out of
your equipment by playing
it at a safe level; a level that
lets the sound come through
clearly 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.
