to the product. Use only with a cart, stand, tripod, bracket, or
table recommended by the manufacturer, or sold with the
product. Any mounting of the product should follow the manu-
facturer’s instructions, and should use a mounting accessory
recommended by the manufacturer.
12) Ventilation - Slots and openings in the cabinet are provid-
ed for ventilation and to ensure reliable operation of the prod-
uct and to protect it from overheating, and these openings
must not be blocked or covered. The openings should never
be blocked by placing the product on a bed, sofa, rug, or other
similar surface. This product should not be placed in a built-in
installation such as a bookcase or rack unless proper ventila-
tion is provided or the manufacturer’s instructions have been
adhered to.

13) Ventilation - The product should be situated so that its
location or position does not interfere with its proper ventila-
tion. For ob a bed, sofa, rug, or similar surface that may block
the ventilation openings: or, placed in a built-in installation,
such as a bookcase or cabinet that may impede the flow of air
through the ventilation openings.
14) Power Sources - This product should be connected to a
power supply only of the type described in the operating
instructions or as marked on the appliance.
15) Grounding or Polarization - This product may be
equipped with a polarized alternating-current line plug (a plug
having one blade wider than the other). This plug will fit into
the power outlet only one way. This is a safety feature. If you
are unable to insert the plug fully into the outlet, try reversing
the plug. If the plug should still fail to fit, contact your electrician
to replace your obsolete outlet. Do not defeat the safety pur-
pose of the polarized plug.

overload protection as the original plug.
18) Cleaning - The product should be cleaned only as recom-
mended by the manufacturer.
19) Power Lines -An outdoor antenna should be located
away from power lines.
20) Outdoor Antenna Grounding - If an outside antenna or
cable system is connected to the product, be sure the antenna
or calbe system is grounded so as to provide some protection
against voltage surges and built-up static charges. Article 810
of the National Electrical Code, ANSI/NFPA 70, provides infor-
mation with regard 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 anten-
na-discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode.

“Note to CATV system installer:
This reminder is provided to call the CATV system installer’s
attention to Section 820-40 of the NEC which provides guide-
lines for proper grounding and, in particular, specifies that the
cable ground shall be connected to the grounding system of
them building, as close to the point of cable entry as practical.

21) Lightning -For added protection for this product during a
lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the wall outlet and discon-
nect the antenna or cable system. This will prevent damage to
the product due to lightning and power-line surges.
22) Power Lings -An outside antenna system should not be
located in the vicinity of overhead power lines or other electric
light or power circuits, or where it can fall into such power lines
or circuits. When installing an outside antenna system,
extreme care should be taken to keep from touching such
power lines or circuits as contact with them might be fatal.
23) Overloading - Do not overload wall outlets, extension
cords, or integral convenience receptacles as this can result in
a risk of fire or electric shock.
24) Nonuse Periods - The power cord of the product should
be unplugged from the outlet when left unused for a long peri-
od of time.
25) Object and Liquid Entry - Never push objects of any kind
into this product through openings as they may touch danger-
ous voltage points or short-out parts that could result in a fire
or electric shock. Never spill liquid of any kind on the product.
26) Damage Requiring Service - Unplug this product from
the wall outlet and refer servicing to qualified service personnel
under the following conditions:
a) When the power-supply cord or plug is damaged.
b) If liquid has been spilled, or objects have fallen into the
product.
c) If the product has been exposed to rain or water.
d) If the product does not operate normally by following the
operating instructions. Adjust only those controls that are cov-
ered by the operat
ing instructions as an improper adjustment of other controls
may result in damage and will often require extensive work by
a qualified technician to restore the product to its normal operation.
e) If the product has been dropped or damaged in any way.
f) when the product exhibits a distinct change in performance-
this indicates a need for service.
27) Servicing - Do not attempt to service this product yourself
as opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified service
personnel.

28) Replacement Parts - When replacement parts are
required, be sure the service technician has used replacement
parts specified by the manufacturer or have the same charac-
teristics as the original part. Unauthorized substitutions may
result in fire, electric shock, or other hazards.
29) Safety Check - Upon completion of any service or repairs
to this product, ask the service technician to perform safety
checks to determine that the product is in proper operating
condition.
30) Heat -The product should be situated away from heat
sources such as radiators, heat registers, stoves, or other

PRECAUTIONS

Read This Before Operating

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.
Do not open the cabinet as this might result in damage
to the circuitry or electrical shock. If a foreign object
should get into the set, contact your dealer.
When removing the power plug from the wall outlet,
always pull directly on the plug, never yank the cord.
Do not attempt to clean the unit with chemical solvents
as this might damage the finish. Use a clean, dry cloth.
Keep this manual in a safe place for future reference.
Remove all of the discs in the tray when you move this
system, to prevent discs from becoming stuck.

This unit has been designed specifically for reproduction of
compact discs bearing the

mark. No other discs can be

reproduced.

Always place the compact disc in the disc tray with the

label facing upward.

(compact discs can be played only on one side.)

To remove a disc from its storage case, press down on

the center of the case and lift the disc out, holding it care-
fully by the edges.

Fingermarks and dust should be carefully wiped off the

disc’s recorded surface with a soft cloth.

Never use chemicals such as record sprays, antistatic
sprays or fluid, benzine or thinner to clean compact discs.
Such chemicals will do irreparable damage to the disc’s
plastic surface.

Discs should be returned to their cases after use to avoid

serious scratches that could cause the laser pickup to
“skip”.
Do not expose discs to direct sunlight or high humidity
and temperature for extended periods.

Long exposure to high temperatures can warp the disc.

Do not stick paper or write anything with a ballpoint pen

on the surface of the label side.
