Important Safety Information
Verify Line Voltage Before Use
YourHK3270 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 requirements for your specific model,
or about the line voltage 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 outlet, 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
immediately, 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 supporting structure, grounding of the leadin wire to an antenna discharge unit,
size of grounding conductors, location of
antenna discharge unit, connection 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’sattention 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 assure 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 pro-
vided 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 circumstances 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.

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.
