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
pinchedorthathardwareisnotlodgedbetweenthechassis
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
havingareturnpathtothechassis(antenna,metalcabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.
AllcheckmustberepeatedwiththeAClinecordplugconnection
reversed.
Anyreading of0.3volt RMS(thiscorrespondsto0.2 milliamp.
AC.) or more is excessive and indicates a potential shock
hazard which must be corrected before returning the audio
product to the owner.

●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.

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

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
