SAFETY INFORMATION
SAFETY INFORMATION
Verify Line Voltage Before Use
Your HKSUB 12 has been designed for use with
120-volt AC current. Connection to a line voltage
other than that for which it is intended can create
a safety and fire hazard and may damage the unit.
If you have any questions about the voltage require-
ments for your specific model, or about the line volt-
age in your area, contact your selling dealer before
plugging the unit into a wall outlet.
Do Not Use Extension Cords
To avoid safety hazards, use only the power cord
attached to your unit. We do not recommend that
extension cords be used with this product. As with
all electrical devices, do not run power cords under
rugs or carpets or place heavy objects on them.
Damaged power cords should be replaced immedi-
ately by an authorized service center with a cord
meeting factory specifications.
Handle the AC Power Cord Gently
When disconnecting the power cord from an AC
outlet, always pull the plug; never pull the cord. If
you do not intend to use the unit for any consider-
able length of time, disconnect the plug from the AC
outlet.
Do Not Open the Cabinet
There are no user-serviceable components inside
this product. Opening the cabinet may present a
shock hazard, and any modification to the product
will void your guarantee. If water or any metal object
such as a paper clip, wire or a staple accidentally
falls inside the unit, disconnect it from the AC power
source immediately, and consult an authorized
service center.
CATV or Antenna Grounding
If an outside antenna or cable system is connected
to this product, be certain that it is grounded so as
to provide some protection against voltage surges
and static charges. Section 810 of the National
Electrical Code, ANSI/NFPA No. 70-1984, provides
information with
respect 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, con-
nection to grounding electrodes and requirements of
the grounding electrode.
NOTE TO CATV SYSTEM INSTALLER:
This
reminder is provided to call the CATV (Cable TV)
system installer’s attention to article 820-40 of the
NEC that provides guidelines for proper grounding
and, in particular, specifies that the cable ground
shall be connected to the grounding system of
the building, as close to the point of cable entry
as possible.
Installation Location
■
To ensure proper operation and to avoid the
potential for safety hazards, place the unit on a
firm and level surface. When placing the unit on a
shelf, be certain that the shelf and any mounting
hardware can support the weight of the product.
■
Make certain that proper space is provided
behind the unit for ventilation. If this product will
be installed in a cabinet or other enclosed area,
make certain that there is sufficient air movement
within the cabinet. Under some circumstances a
fan may be required.
■
Do not place the unit directly on a carpeted sur-
face.
■
Avoid installation in extremely hot or cold loca-
tions, or in an area that is exposed to direct sun-
light or heating equipment.
■
Avoid moist or humid locations.
■
Do not place the unit so that the back panel is
touching a wall, plants or any other surface. Allow
at least three inches from the metal panel on the
back of the unit to any other object.
■
Due to the weight of the HKSUB 12 and the heat
generated by the amplifier, there is the remote
possibility that the rubber padding on the bottom
of the unit’s feet may leave marks on certain
wood or veneer materials. Use caution when
placing the unit on soft woods or other materials
that may be damaged by heat or heavy objects.
Cleaning
When the unit gets dirty, wipe it with a clean, soft,
dry cloth. If necessary, wipe it with a soft cloth
dampened with mild soapy water, then a fresh cloth
with clean water. Wipe dry immediately with a dry
cloth. NEVER use benzene, aerosol cleaners, thinner,
alcohol or any other volatile cleaning agent. Do not
use abrasive cleaners, as they may damage the fin-
ish of metal parts. Avoid spraying insecticide near
the unit.
Moving the Unit
Before moving the unit, be certain to disconnect
any interconnection cords with other components,
and make certain that you disconnect the unit from
the AC outlet.
Important Information for the User
This equipment has been tested and found to com-
ply with the limits for a Class-B digital device, pur-
suant to Part 15 of the FCC Rules. The limits are
designed to provide reasonable protection against
harmful interference in a residential installation. This
equipment generates,
uses and can radiate radio-
frequency energy
and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communication. However, there
is no guarantee that harmful interference will not
occur in a particular installation. If this equipment
does cause harmful interference to radio or televi-
sion reception, which can be determined by turning
the 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 equipment
and receiver.
■
Connect the equipment into an outlet on a circuit
different from that to which the receiver is con-
nected.
■
Consult the dealer or an experienced radio/TV
technician for help.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept interference
received, including interference that may cause
undesired operation.
NOTE:
Changes or modifications may cause this
unit to fail to comply with Part 15 of the FCC Rules
and may void the user’s authority to operate the
equipment.
Unpacking
The carton and shipping materials used to protect
your new loudspeaker(s) during shipment were spe-
cially designed to cushion it (them) from shock and
vibration. We
suggest that you save the carton and
packing materials
for use in shipping if you move, or
should the speaker(s) ever need repair.
To minimize the size of the carton in storage, you
may wish to flatten it. This is done by carefully slit-
ting the tape seams on the bottom and collapsing
the carton. Other cardboard inserts may be stored in
the same manner. Packing materials that cannot be
collapsed should be saved along with the carton in
a plastic bag.
If you do not wish to save the packaging materials,
please note that the carton and other sections of the
shipping protection are recyclable. Please respect
the environment and discard those materials at a
local recycling center.
