Note
This equipment has been tested and found to

vice, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protec-

tee that interference will not occur in a particu-

equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equip-
ment and receiver.
- Connect the equipment into an outlet on a cir-
cuit different from that to which the receiver is
connected.
- Consult the dealer or an experienced radio/TV
technician for help.
The Safety of Your Ears is in
Your Hands 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 dis-
tortion 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 nor-
mal can actually be loud and harmful to your
hearing. Guard against this by setting your
equipment at a safe level BEFORE your hearing
adapts. ESTABLISH A SAFE LEVEL:! Set your volume control at a low setting.
! Slowly increase the sound until you can hear
it comfortably and clearly, without distortion.
! Once you have established a comfortable
sound level, set the dial and leave it there. BE SURE TO OBSERVE THE
FOLLOWING GUIDELINES: !Do not turn up the volume so high that you
can t hear what s around you.
! Use caution or temporarily discontinue use
in potentially hazardous situations.
! Do not use headphones while operating a
motorized vehicle; the use of headphones
may create a traffic hazard and is illegal in
many areas.
