WARNING: When using electrical products, basic precautions should
always be observed, including the following:
1. Read these instructions thoroughly and retain for future reference.
2. Head all warnings, and follow all instructions.
3. Do not use this apparatus near water.
4. Clean only with a dry cloth.
5. Do not block any of the ventilation openings. Install in
accordance with manufacturer’s instructions.
6. Do not install near any heat sources such as radiators, heat
registers, stoves or other apparatus (including amplifiers) that
produce heat.
7. Do not disable the safety purpose of the polarized plug, or
grounding-type plug. A polarized plug has two blades with one
prong wider than the other. A grounding plug has two blades and
a third grounding prong. The wide blade or third prong is
provided for your safety. Never break off the ground pin. Connect
only to a power supply of the type marked on the unit adjacent to
the power supply cord. If the provided plug does not fit into your
outlet, consult an electrician for replacement of the obsolete
outlet.
8. Protect the power cord from being pinched or stepped on,
particularly at plugs, convenience receptacles, and the point at
which they exit from the apparatus.
9. Use only those attachments/accessories provided by the
manufacturer.
10. Unplug this apparatus during lightning storms, or when unused for
long periods of time.
11. Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way, such
as: power cord or plug is damaged, liquid has been spilled or
objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, the apparatus does not operate
normally or the apparatus has been dropped.
12. If this apparatus is to be mounted in an equipment rack, rear
support should be provided.
13. 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 lose some
hearing if exposed to sufficiently intense noise for a sufficient
time. The U.S. Government’s Occupational and Health
Administration (OSHA) has specified the following permissible
noise level exposures:
Duration per Day in Hours Sound Level dBA, Slow Response
8 90
6 92
4 95
3 97
2 100
1-1/2 102
1 105
1/2 110
1/4 or less 115
According to OSHA, any exposure in excess of the above permissible
limits could result in some hearing loss. Ear plugs or protectors to the
ear canals or over the ears must be worn when operating this
amplification system 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 amplification system
be protected by hearing protectors while the unit is in operation.
