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,terminalboard,adjustmentandcompartmentcovers
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 of0.3 voltRMS (thiscorresponds to0.2 milliamp.
AC.) or more is excessive and indicates a potential shock
hazard which must be corrected before returning the audio
product to the owner.

TEST MODE
Figure 12-2 Figure 12-3
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.

Only in STOP state it is possible to slide the pickup with the ( ) or ( ) key.

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
electrolyticcapacitor,theexpression“capacitance/withstand
voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
