EXPOSURE TO EXTREMELY HIGH NOISE LEVELS MAY CAUSE A PERMANENT
HEARING LOSS. INDIVIDUALS VARY CONSIDERABLY IN SUSCEPTIBILITY TO
NOISE INDUCED HEARING LOSS, BUT NEARLY EVERYONE WILL LOSE SOME
HEARING IF EXPOSED TO SUFFICIENTLY INTENSE NOISE FOR A SUFFICIENT
TIME. THE U.S. GOVERNMENT'S OCCUPATIONAL SAFETY AND HEALTH
ADMINISTRATION (OSHA) HAS SPECIFIED THE FOLLOWING PERMISSIBLE
NOISE LEVEL EXPOSURES:

ACCORDING TO OSHA, ANY EXPOSURE IN EXCESS OF THE ABOVE
PERMISSIBLE LIMITS COULD RESULT IN HEARING LOSS. EAR PLUGS OR
PROTECTORS IN THE EAR CANALS OR OVER THE EARS MUST BE WORN
WHEN OPERATING THIS DEVICE IN ORDER TO PREVENT A PERMANENT
HEARING LOSS. IF EXPOSURE IS IN EXCESS OF THE LIMITS AS SET FORTH
ABOVE, TO ENSURE AGAINST POTENTIALLY DANGEROUS EXPOSURE TO
HIGH SOUND PRESSURE LEVELS, IT IS RECOMMENDED THAT ALL PERSONS
EXPOSED TO EQUIPMENT CAPABLE OF PRODUCING HIGH SOUND
PRESSURE LEVELS SUCH AS THIS DEVICE BE PROTECTED BY HEARING
PROTECTORS WHILE THIS UNIT IS IN OPERATION.
1. Read all safety and operating instructions before using this product.
2. All safety and operating instructions should be retained for future reference.
3. Obey all cautions in the operating instructions and on the unit.
4. All operating instructions should be followed.
5. This product should not be used near water, i.e a bathtub, sink, swimming pool,
wet basement, etc.
6. This product should be located so that its position does not interfere with its
proper ventilation. It should not be placed flat against a wall or placed in a built-in
enclosure that will impede the flow of cooling air.
7. This product should not be placed near a source of heat such as a stove or
radiator.
8. Connect only to a power supply of the type marked on the unit adjacent to the
power.
9. Never break off the ground pin on the power supply cord.
10. Power supply cords should always be handled carefully. Never walk or place
equipment on power supply cords. Periodically check cords for cuts or signs of
stress, especially at the plug and the point where the cord exits the unit.
11. The power supply cord should be unplugged when the unit is to be unused for
long periods of time.
12. Care should be taken so that objects do not fall and liquids are not spilled into
the unit through the ventilation holes or any other openings.
13. This unit should be checked by a qualified service technician if:
A. The power supply cord or plug has been damaged.
B. Anything has fallen or been spilled into the unit.
C. The unit does not operate correctly.
D. The unit has been dropped or the enclosure damaged.
14. The user should not attempt to service this equipment. All service work should
be done by a qualified service technician.
