INFORMATION

Verify Line Voltage Before Use
Your HK 3470 has been designed for use with
220-240-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 fac-
tory 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 con-
siderable 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 prod-
uct 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 con-
sult an authorized service station.

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 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 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.

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 immedi-
ately 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 compo-
nents, and make certain that you disconnect the
unit from the AC outlet.

The carton and shipping materials used to pro-
tect 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 care-
fully 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. Pack-
ing 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 materi-
als, please note that the carton and other sec-
tions of the shipping protection are recyclable.
Please respect the environment and discard
those materials at a local recycling center.
