IMPORTANT SERVICE NOTES (For U.S.A.Only)

BEFORE RETURNING THE AUDIO PRODUCT

(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.

1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the chassis
and other metal parts in the audio product.

2. Inspect all protective devices such as insulating materials,
cabinet, terminal board, adjustment and compartment
covers or shields, mechanical insulators etc.

3. To be sure that no shock hazard exists, check for leakage
current in the following manner.

* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5k ohm, 10 watt resistor

paralleled by a 0.15µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.

* Use a VTVM or VOM with 1000 ohm per volt, or higher,

sensitivity to measure the AC voltage drop across the
resistor (See diagram).

* Connect the resistor connection to all exposed metal parts

having a return path to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.

hazard which must be corrected before returning the audio
product to the owner.

Precaution

Precaución

● Label facing up

● Load the disc to be recorded. ● CD recording starts.

● The sound level at a given volume setting

depends on a combination of speaker effi-

ciency, location and many other factors. It is

advisable to avoid exposure to high volume

levels, which occur while turning the unit on

with the volume control setting up high, or

while continually listening at high volume le-

vels.

● Only discs bearing the logo as shown can

be played in this unit.

●

Etiqueta hacia arriba

●

Introduzca el disco que va a grabar.

●

La grabación de CD empieza.

●

El nivel de sonido en una posición de volumen

fijado depende de una combinación del rendi-

miento de las altavoces, la posición y muchos

otros factores. Es aconsejable evitar un aumen-

to de volumen. Esto se produce, por ejemplo,

al conectar el aparato con el volumen puesto

en una posición alta. Evite continuar la audición

prolongada a altos niveles de sonido.

●

En este aparato sólo pueden reproducirse los

discos que tengan el logotipo mostrado.

NOTES ON SCHEMATIC DIAGRAM

• Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.

• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression “capacitance/withstand
voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type

• Schematic diagram and Wiring Side of P.W.Board for this
model are subject to change for improvement without prior
notice.

CD-C452/C452C

• The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chas­sis with no signal given.

1. In the tuner section,

( ) indicates AM
< > indicates FM stereo

2. In the main section, a tape is being played back.

3. In the deck section, a tape is being played back.

( ) indicates the record state.

4. In the power section, a tape is being played back.

5. In the CD section, the CD is stopped.

• Parts marked with “ ” ( ) are important for
maintaining the safety of the set. Be sure to replace these
parts with specified ones for maintaining the safety and
performance of the set.
