18. Exposure to extremely high noise levels may cause
permanent hearing loss. Individuals vary considerably
in susceptibility to noise-induced hearing loss, but
nearly everyone will loss some hearing if exposed to
sufficiently intense noise for a period of time. The U.S.
2
Government's Occupational Safety and Health
Administration (OSHA) have specified the permissible
noise level exposures shown in the following chart.
According to OSHA, any exposure in excess of
these permissible limits could result in some hearing
loss. 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 use hearing
protectors while the equipment is in operation. Ear
plugs or protectors in the ear canals or over the ears
must be worn when operating the equipment in order
to prevent a permanent hearing loss if exposure is in
excess of the limits set forth here.
AC-Power Sources
This set should be operated only from the type of
power source indicated on the marking label. If you
are not sure of the type of electrical power supplied to
your home, consult your dealer or local power
company. For those sets designed to operate from
battery power, or other sources, refer to the operating
instructions.
Overloading
Do not overload wall outlets, extension cords or
convenience receptacles beyond their capacity, since
this can result in fire or electric shock.
An appliance and cart combination
should be moved with care. Quick
stops, excessive force and uneven
surfaces may cause the appliance
and cart combination to overturn.
Accessories
Do not place the set on an unstable cart, stand, tripod,
bracket, or table. The set may fall, causing serious
injury to a child or an adult, and serious damage to
the set. Use only a cart stand tripod, bracket, or table
recommended by the manufacturer.
For the set with a three-wire grounding type ac plug:
This plug will only fit into a grounding-type power
outlet. This is a safety feature. If you are unable to
insert the plug into the outlet, contact your electrician to
have a suitable outlet installed. Do not defeat the
safety purpose of the grounding plug.

SAFETY PRECAUTIONS
Selecting fine audio equipment such as the unit you've just
purchased is only the first step to your musical enjoyment.
Now it's time to consider how you can maximize the fun and
the safety of your new equipment. We want you to get the
most out of your equipment by playing it at a safe level
without affecting your hearing. Sound can be very harmful.
Over time your hearing "comfort level" adapts to higher
volume of sound. What sounds "normal" can actually be loud
and harmful to your hearing. Therefore, please guard against
this by setting your equipment at a safe level before your
hearing adapts. To establish a safe level, you can start your
volume control at a low setting, then slowly increase the sound
until you can hear it comfortably and clearly. If used wisely,
your new sound equipment will provide you a pleasant
experience in music. Since hearing damage from loud noise
is often undetectable until it is too late, we recommend you
avoid prolonged exposure to excessive noise. The following
noises can be dangerous under constant exposure. Therefore,
please be cautious with the dB level when playing your new
equipment.
Decible Level Example
120 dB Rock band concert in front of
speakers, thunderclap
140 dB Gunshot blast, jet plane
180 dB Rocket launching pad
