REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated “dangerous voltage” within the
product’s enclosure that may be of sufficient magnitude
to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the appliance.
o Do not expose this apparatus to drips or splashes.
o Do not place any objects filled with liquids, such as vases, on the
apparatus.
o Do not install this apparatus in a confined space such as a book
case or similar unit.
o The apparatus draws nominal non-operating power from the
AC outlet with its POWER or STANDBY/ON switch not in the ON
position.
o The apparatus should be located close enough to the AC outlet so
that you can easily grasp the power cord plug at any time.
o The mains plug is used as the disconnect device, the disconnect
device shall remain readily operable.
o Products with Class © construction are equipped with a power
supply cord that has a 3-prong grounding plug. The cord of such
a product must be plugged into an AC outlet that has a protective
grounding connection.
o If the product uses batteries (including a battery pack or installed
batteries), they should not be exposed to sunshine, fire or excessive
heat.
o Caution should be taken when using earphones or headphones
with the product because excessive sound pressure (volume) from
earphones or headphones can cause hearing loss.

Before Use
Bottom plate
of the unit
Spike foot
Protection foot Retaining screws
Read this before attempting any operations.
Placement of the unit
This unit is heavy. Take care to prevent injuries when lifting and
installing it.
o High-quality tool steel is used for the spike feet, securely attached
to the bottom of the unit. Although the outer feet may appear
loose, the weight of the unit causes them to become firm and
secure. The design effectively damps and reduces vibration.
To protect the supporting furniture surface, you may stick the
supplied felt pads to the bottom of the protection feet.
o Place the unit in a stable location near the audio system that you
will use.
o Choose the installation location of your unit carefully. Avoid placing
it in direct sunlight or close to a source of heat. Also avoid locations
subject to vibrations and excessive dust, heat, cold or moisture.
o As the unit may become warm during operation, always leave
sufficient space around the unit for ventilation.
Make sure there is at least 8” (20 cm) of space above and at least 2”
(5 cm) of space on each side of the unit.
When you install the unit in a rack, use one which has ventlations
and take care of temperature of the unit.
CAUTION
o Do not place any objects on this unit.
o Do not cover this unit with a cloth.
o The voltage supplied to the unit should match the voltage as
printed on the rear panel. If you are in any doubt regarding this
matter, consult an electrician.
o Do not open the cabinet as this might result in damage to the
circuitry or cause electric shock. If a foreign object should get into
the unit, contact your dealer or service company.
o When removing the power plug from the wall outlet, always pull
directly on the plug, never yank on the cord.
Maintenance
If the surface of the unit gets dirty, wipe it with a sof t cloth or
use diluted mild liquid soap. Allow the surface of the unit to dry
completely before using.
For safety, disconnect the power cord from the socket before
cleaning.
o Never spray liquid directly on this unit.
o Do not use thinner or alcohol as they could damage the surface of
the unit.
o Avoid allowing rubber or plastic materials to touch this product for
long periods of time. It could damage the cabinet.
o Do not place this unit on a thick carpet.
o When the unit is turned on, switching on the TV may cause lines
to appear on the TV screen, depending on the condition of the
electric waves of the TV broadcast. This is not malfunction in the
unit or the T V. If you see such lines, keep this unit well away from
the TV set.

operation by remote control might be impossible if there are any
obstacles between the unit and the remote control.
o If direct sunlight or strong artificial illumination shines on the
remote sensor, the remote control might not function.
o If the remote control unit is operated near other devices that
generate infrared rays, or if other remote controls that use infrared
rays are operated near the unit, this unit might operate incorrectly.
The other devices might also operate incorrectly.
Battery Replacement
If the operating range between the remote control unit and main
unit decreases, the batteries are exhausted. In this case replace the
batteries with new ones.
For more information about collection of batteries, please contact
your local municipality, your waste disposal service or the point of sale

batteries together.
o Both rechargeable and non-rechargeable batteries can be used.
Refer to the precautions on their labels.
o If the remote control will not be used for a long time (more than a
month), remove the batteries to prevent them from leaking.
o If the batteries leak, wipe away the leakage inside the battery
compartment and replace the batteries with new ones.
o Do not use batteries of types other than those specified. Do not
mix new batteries with old ones or use different types of batteries
tog ether.
o Do not heat or disassemble batteries. Never throw batteries into
fire or water.
