(including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding
type plug has two blades and a third grounding
prong. The wide blade or the third prong are pro-
vided for your safety. If the provided plug does not

tus.
11. Only use attachments/accessories specified by the
manufacturer.
12. Use only with the cart, stand,
tripod, bracket, or table spec-
ified by the manufacturer, or
sold

the
apparatus.
When a cart is used, use cau-
tion when moving the cart/
apparatus
combination

E. If the apparatus has been dropped or damaged in
any way, and
F. When the apparatus exhibits a distinct change in
performance this indicates a need for service.

Precautions
1. Recording Copyright
Unless it's for personal use only, recording copy-
righted material is illegal without the permission of
the copyright holder.
2. AC Fuse
The AC fuse inside the DX-C34 is not user-service-
able. If you cannot turn on the DX-C34, contact your
Onkyo dealer.
3. Care
Occasionally you should dust the DX-C34 all over
with a soft cloth. For stubborn stains, use a soft cloth
dampened with a weak solution of mild detergent
and water. Dry the DX-C34 immediately afterwards
with a clean cloth. Don't use abrasive cloths, thin-
ners, alcohol, or other chemical solvents, because
they may damage the finish or remove the panel let-
tering.
4. Power
WARNING
BEFORE PLUGGING IN THE UNIT FOR THE
FIRST TIME, READ THE FOLLOWING SEC-
TION CAREFULLY.
AC outlet voltages vary from country to country.
Make sure that the voltage in your area meets the
voltage requirements printed on the DX-C34's rear
panel (i.e., AC 120 V, 60 Hz).
Setting the [STANDBY/ON] switch to STANDBY
does not fully shutdown the DX-C34. If you do not
intend to use the DX-C34 for an extended period,
remove the power cord from the AC outlet.
5. Never Touch This Unit with Wet Hands
Never handle this unit or its power cord while your
hands are wet or damp. If water or any other liquid
gets inside this unit, have it checked by your Onkyo
dealer.
6. Installing This Unit
· Install this unit in a well-ventilated location.
· Ensure that there's adequate ventilation all around
this unit, especially if it's installed in an audio
rack. If the ventilation is inadequate, the unit may
overheat, leading to malfunction.
· Do not expose this unit to direct sunlight or heat
sources, because its internal temperature may rise,
shortening the life of the optical pickup.
·Avoid damp and dusty places, and places subject
to vibrations from loudspeakers. Never put the
unit on top of, or directly above a loudspeaker.
· Install this unit horizontally. Never use it on its
side or on a sloping surface, because it may cause
a malfunction.
· If you install this unit near a TV, radio, or VCR,
the sound quality may be affected. If this occurs,
move this unit away from the TV, radio, or VCR.
7. Moisture Condensation
Moisture condensation may damage this unit.
Read the following carefully:
When you take a glass containing a cold drink out-
side on a summer's day, drops of water, called con-
densation, form on the outside of the glass.
Similarly, moisture may condense on the lens of the
optical pickup, one of the most important parts
inside this unit.
· Moisture condensation can occur in the following
situations:
-- The unit is moved from a cold place to a warm
place.
--A heater is turned on, or cold air from an air
conditioner is hitting the unit.
-- In the summer, when this unit is moved from
an air conditioned room to a hot and humid
place.
-- The unit is used in a humid place.
· Do not use this unit when there's the possibility of
moisture condensation occurring. Doing so may
damage your discs and certain parts inside this
unit.
If condensation does occur, remove all discs and
leave this unit turned on for two to three hours. By
this time, the unit will have warmed up and any con-
densation will have evaporated. To reduce the risk of
condensation, keep this unit connected to a wall out-
let.
