1. Unpacking: Check the product
carefully. If it has been damaged in
transit, report the damage immedi-
ately by calling your dealer and/or the
shipping company that delivered it.
2. Connections: Whenever changing,
connecting or disconnecting signal or
power cables etc., always turn off all
equipment. This prevents transients
from entering the equipment and pre-
vents electrical energy from reaching
you. Keep all connections out of the
reach of children. Before moving the
unit, be certain to disconnect any
interconnection cords with other
components, and make certain that
you disconnect any powered units
from the AC outlet.
3. Read Instructions. All the safety
and operating instructions should be
read before the product is operated.

17. If an outside antenna or cable 
system is connected to the product, 
be sure the antenna or cable system 
is grounded so as to provide some 
protection against voltage surges and
built-up static charges. Article 810 of
the National Electrical Code, ANSI/
NFPA 70, provides information with
regard to proper grounding of the
mast and supporting structure,
grounding of the lead-in wire to an

antenna discharge unit, size of
grounding conductors, location of
antenna-discharge unit, connection
to grounding electrodes, and require-
ments for the grounding electrode.
See Figure A.
18. An outside antenna system should
not be located in the vicinity of over-
head power lines or other electric
light or power circuits, or where it
can fall into such power lines or cir-
cuits. When installing an outside
antenna system, extreme care should
be taken to keep from touching such
power lines or circuits, as contact
with them might be fatal.
19. Specifications: All product
specifications/features are subject to
change without notification.

Passive Products:
20. Amplifiers: Amplifiers used to
drive these units must deliver a suffi-
cient output power. A lack of output
power may lead to amplifier-clipping,
which causes damage not covered by
guarantee.

Active (Powered) Products:
21. Ventilation. Slots and openings in
the cabinet are provided for ventila-
tion and to ensure reliable operation
of the product and to protect it from
overheating, and these openings
must not be blocked or covered. The
openings should never be blocked by
placing the product on a bed, sofa,
rug, or other similar surface. This
product should not be placed in a
built-in installation such as a book-
case or rack unless proper ventilation
is provided or the manufacturer’s
instructions have been adhered to.
Make certain that the proper space
(more than 10cm) is provided both
above and below the unit for ventila-
tion. If the amplifier will be installed in
a cabinet or other enclosed area,
make certain that there is sufficient
air movement within the cabinet, with
means provided for hot air to exit and
for cool air to be brought in.
Do not obstruct the ventilation slots
on the top of the unit or place objects
directly over them. Remember, power
amplifiers generate heat, and the
heatsink fins and ventilation slots that
form part of the cabinet are specially
designed to remove this heat. Placing
other electronic equipment near
these heat-dissipation systems may
possibly affect the long term reliabil-
ity of both your amplifier and the
objects placed above it. Do not place
CDs, record jackets, owner’s manuals
or other paper on top of or beneath
the unit or in between products con-
taining amplifiers in a stack. This will
block the air flow, causing degraded
performance and a possible fire haz-
ard.

22. Power Sources. This product
should be operated only from the type
of power source indicated on the
marking label. If you are not sure of
the type of power supply to your
home, consult your product dealer or
local power company. For products
intended to operate from battery
power, or other sources, refer to the
operating instructions.
23. Grounding or Polarization. This
product may be equipped with a polar-
ized alternating-current line plug (a
plug having one blade wider than the
other). This plug will fit into the power
outlet only one way. This is a safety
feature. If you are unable to insert the
plug fully into the outlet, try reversing
the plug. If the plug should still fail to
fit, contact your electrician to replace
your obsolete outlet. Do not defeat the
safety purpose of the polarized plug.
24. Power-Cord Protection. Power-
supply cords should be routed so that
they are not likely to be walked on or
pinched by items placed upon or
against them, paying particular atten-
tion to cords at plugs, convenience
receptacles, and the point where
they exit from the product. To avoid
safety hazards, use only the power
cord supplied with your unit. If a
replacement cord is used, make cer-
tain that it is of a similar gauge. We
do not recommend using extension
cords with this product. As with all
electrical devices, do not run power
cords under rugs or carpets or place
heavy objects on power cords. Dam-
aged power cords should be replaced
immediately, by a qualified service
technician, with cords meeting fac-
tory specifications. When discon-
necting the power cord from an AC
outlet, always pull the plug; never pull
the cord.
25. Non-use Periods. The power cord
of the product should be unplugged
from the outlet when left unused for
long periods of time.
26. Lightning. For added protection
for this product during a lightning
storm, or when it is left unattended
and unused for long periods of time,
unplug it from the wall outlet and dis-
connect the antenna or cable system.
This will prevent damage to the prod-
uct due to lightning and power-line
surges.
27. Overloading. Do not overload wall
outlets, extension cords, or integral
convenience receptacles, as this can
result in a risk of fire or electric shock.

28. Damage Requiring Service. Do
not attempt to service this product
yourself, as opening or removing cov-
ers may expose you to dangerous
voltage or other hazards. Unplug this
product from the wall outlet and refer
servicing to qualified service person-
nel under the following conditions:
a. The power-supply cord or the plug

has been damaged; or

b. Objects have fallen, or liquid has

been spilled into, the product; or

c. The product has been exposed to

rain or water; or

d. The product does not operate nor-

mally when following the operating
instructions. Adjust only those con-
trols that are covered by the oper-
ating instructions, as an improper
adjustment of other 
controls may result in damage and
will often require extensive work by
a qualified technician to restore the
product to its normal operation; or

e. The product has been dropped, or

the enclosure damaged; or

f. The product does not appear to

operate normally or exhibits a
marked change in performance.

29. Object and Liquid Entry. Never
push objects of any kind into this prod-
uct through openings, as they may
touch dangerous voltage points or
short-out parts that could result in a
fire or electric shock. Never spill liquid
of any kind on the product. The appa-
ratus shall not be exposed to dripping
or splashing and no objects filled with
liquids, such as vases, shall be placed
on the apparatus.
30. Heat. The product should be situ-
ated away from heat sources such as
radiators, heat registers, stoves or
other products (including amplifiers)
that produce heat. Avoid installation
in extremely hot or cold locations, in
an area that is exposed to direct sun-
light or near heating equipment.
When positioning the product in its
final location, make certain that it has
adequate ventilation on all sides, as
well as on the top and bottom.
