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 1.5 kohm, 10 watt resistor paralleled by a 0.15 μF 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.

Condensation
Sudden temperature changes, storage or operation in an extremely humid environment may cause condensation inside the cabinet (CD pick-
up, tape heads, etc.) or on the transmitter on the
remote control. Condensation can cause the unit to malfunction. If this happens, leave the power on with no disc (or cassette) in the unit until normal playback is possible (about 1 hour). Wipe off any condensation on the transmitter with a soft cloth before op-
erating the unit.

Troubleshooting chart
If trouble occurs
When this product is subjected to strong external interference (mechanical shock, excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction.
If such a problem occurs, do the following:
1Set the unit to the stand-by mode and turn the power on again.
2If the unit is not restored in the previous operation, unplug and plug in the unit, and then turn the power on.
Note:
If neither operation above restores the unit, clear all the memory by resetting it.
Clearing all the memory (reset)
1Press the ON/STAND-BY button to enter the power stand-by mode.
2While pressing down the CLOCK button and the EQUALIZER/X-BASS/DEMO button, press the ON/STAND-BY button until "CLEAR AL" appears.
Caution:
This operation will erase all data stored in memory including clock, timer settings, tuner preset, and CD program.
Before transporting the unit
On the back of this unit is equipped with a transport screw in order to prevent damage during transportation.
1 Press the ON/STAND-BY button to turn the
power on. 2 Press the CD button. 3 Press the OPEN/CLOSE button to open
the disc tray.
Remove all CDs inserted in the unit.
4 Press the OPEN/CLOSE button to close the disc tray.
Make sure that "NO DISC" is displayed.
5 Press the ON/STAND-BY button to enter the stand-by mode, and then unplug the AC power cord from the AC outlet.

CD SECTION
•Adjustment
Since this CD system incorporates the following automatic adjustment functions, readjustment is not needed when replacing the pickup. Therefore, different PWBs and pickups can be combined freely.
Each time a disc is changed, these adjustments are performed automatically. Therefore, playback of each disc can be performed under optimum conditions.
Items adjusted automatically
(1)Offset adjustment (The offset voltage between the head amplifier output and the VREF reference voltage is compensated inside the IC.)
*Focus offset adjustment
*Tracking offset adjustment
(2)Tracking balance adjustment (waveform drawing Fig.15-2 EFBL)
(3)Gain adjustment (The gain is compensated inside the IC so that the loop gain at the gain crossover frequency will be 0 dB.)
*Focus gain adjustment
*Tracking gain adjustment

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