IMPORTANT SAFEGUARDS
Please read all of the safety and operating instructions
before operating this unit. For best results, follow all
warnings placed on the unit and adhere to the operat-
ing and use instructions. These safety and operating in-
structions should be retained for future reference.
1. Power sources — The unit should be connected
to a power suppiy only of the type described in the
operating instructions or as marked on the appliance.
2. Power-cord protection — Power-supply cords
should be routed so that they are not likely to be
walked on or pinched by items placed upon or
against them, pay particular attention to cords at
plugs, convenience receptacles, and the point where
they exit from the unit.
Never pull or stretch
the cord.
3. Grounding or polarization — The precautions
should be taken so that the grounding or polariza-
tion means of this unit is not defeated.
4, Ventilation — The unit should be situated so that
its location or position does not interfere with its
proper ventilation.
To maintain good ventilation, do not put records or
a table-cloth on the unit. Place the unit at least
10 cm away from the walls.
Do not use the unit on a bed, sofa, rug or similar
surface that may block the ventilation openings.
5. Water and moisture — The unit should not be
used near water — for example, near a bathtub,
washbowil, kitchen sink, laundry tub, in a wet base-
ment, or near a swimming pool, etc.
6. Temperature — The unit may not function pro-
perly if used at extremely low, or freezing tempera-
tures. The ideal ambient temperature is above + 5°C
(41°F).
à kD-491F/491FC (En)
À Caution : Read this page carefully to ensure
safe operation.
7.Heat — The unit should be situated away from
heat sources such as radiators, heat registers,
stoves, or other units {including amplifiers) that
produce heat.
8. Electric shock — Care should be taken so that ob-
jects do not fail and liquid is not spilled into the en-
closure through openings. If a metal object, such as
a hair pin or a needle, comes into contact with the
inside of this unit, a dangerous electric shock may
result. For families with children, never permit chil-
dren to put anything, especially metal, inside this
unit.
9. Enclosure removal — Never remove the en-
closure. If the internal parts are touched accidentally,
a serious electric shock might occur.
10. Magnetic fields — Keep the unit away from
sources of magnetic fields such as TV sets, speaker
systems, radios, motorized toys or magnetized
objects.
11. Cleaning — Do not use volatile solvents such as
alcohol, paint thinner, gasoline, or benzine, etc. to
clean the cabinet. Use a clean dry cloth.

Carts and stands — An appliance and cart com-
bination should be moved with care. Quick stops,
excessive force, and uneven surfaces may cause the
appliance and cart combination to overturn.
O
Nonuse periods — The power cord of the unit
should be unplugged from the outlet when left un-
used for a long period of time.
Abnormal smell — If an abnormal smeli or smoke
is detected, immediately turn the power OFF and pull
out the power cord. Contact your dealer or nearest
service center. POWER OFF!
Damage requiring service — The unit should be
serviced by qualified service personnel when:
A. The power-supply cord or the plug has been
damaged; or
B. Objects have fallen, or liquid has been spilled into
the unit; or
C. The unit has been exposed to rain; or
D. The unit does not appear to operate normally or
exhibits a marked change in performance; or
E. The unit has been dropped, or the enclosure
damaged.
Servicing — The user should not attempt to ser-
vice the unit beyond that described in the operating
instructions. All other servicing should be referred
to qualified service personnel.
Outdoor antenna grounding — If an outside an-
tenna is connected to the receiver, be sure the an-
tenna system is grounded so as to provide some
protection against voltage surges and built up 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 lead-in wire
to an antenna discharge unit, size of grounding con-

Periodic check-up
Because a turntable is a mechanical! device it is subject to the ef-
fects of wear and misadjustment that occurs due to normal han-
dling. Even if your unit appears to function normally, a periodic
check-up at intervals of two years or so is recommended to ensure
a long service life and proper operation,
Check with your dealer or authorized service representative.

Notes:
1. As this system uses microprocessors, it may not function properly due to external noise or interference noise. If this happens, disconnect the
power plug from the outlet, wait several seconds, then reconnect.
2. Do not use contact cleaner because it could cause a malfunction. Be specially careful against contact cleaners containing oil, for they may
deform the plastic components.
