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.
All check must be repeated with the AC line cord plug connection reversed.
Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp. AC.) or more is excessive and indicates a potential shock hazard which must be corrected before returning the audio product to the owner.

Precaution
Precaución
●The sound level at a given volume setting depends on a combination of speaker efficiency, 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 levels.
●Only discs bearing the logo as shown can be played in this unit.
●El nivel de sonido en una posición de volumen fijado depende de una combinación del rendimiento de las altavoces, la posición y muchos otros factores. Es aconsejable evitar un aumento 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.

Precaution
Precaución
●The sound level at a given volume setting depends on a combination of speaker efficiency, 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 levels.
●Only discs bearing the logo as shown can be played in this unit.
●El nivel de sonido en una posición de volumen fijado depende de una combinación del rendimiento de las altavoces, la posición y muchos otros factores. Es aconsejable evitar un aumento 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.

CD SECTION
Since this CD system incorporates the following automatic adjustment function, when the pickup is replaced, it is not necessary to readjust it.
Since this CD unit does not need adjustment, the combination of PWB and laser pickup unit is not restricted.
• Automatic adjustment item
1.Focus offset (Fig. 12-2)
2.Tracking offset (Fig. 12-3)
3.E/F balance (tracking error balance) (Fig. 12-4)
4.RF level AGC function (HF level: constant)
5.RF level automatic follow-up of the tracking gain
This automatic adjustment is performed each time a disc is changed. Therefore, each disc is played back using the optimal settings.

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.
