4 SAFETY INFORMATION
Important Safety Information
Verify Line Voltage Before Use
Your HK 3380 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 immediately with
cords meeting factory specifications.
Handle the AC Power Cord Gently
When disconnecting the power cord from an AC out-
let, always pull the plug, never pull the cord. If you do
not intend to use the unit for any considerable 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 staple accidentally falls inside the
unit, disconnect it from the AC power source immedi-
ately, and consult an authorized service station.
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 sup-
porting 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 requirements of the ground-
ing 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 par-
ticular, specifies that the cable ground shall be con-
nected 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 hard-
ware can support the weight of the product.
■ Make certain that proper space is provided both
above and below 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 cir-
cumstances a fan may be required.
■ Do not place the unit directly on a carpeted
surface.
■ Avoid installation in extremely hot or cold locations,
or an area that is exposed to direct sunlight or
heating equipment.
■ Avoid moist or humid locations.
■ Do not obstruct the ventilation slots on the top of
the unit, or place objects directly over them.
■ Due to the weight of the HK 3380 and the heat
generated by the amplifiers, there is the remote
possibility that the rubber padding on the bottom
of the unit’s feet may leave markings on certain
wood or veneer materials. Use caution when plac-
ing 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 finish 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
NOTE:
This equipment has been tested and found
to comply with the limits for a Class-B digital device,
pursuant 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 television 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 connected.
■ 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 receiver during shipment were specially designed
to cushion it from shock and vibration. We suggest
that you save the carton and packing materials for
use in shipping if you move, or should the unit ever
need repair.
To minimize the size of the carton in storage, you may
wish to flatten it. This is done by carefully slitting the
tape seams on the bottom and collapsing the carton
down to a more two-dimensional appearance. 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.
At this time you should remove the protective plastic
film from the front-panel lens. Leaving the film in place
will affect the performance of your remote control.
