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 condensa-

tion on the transmitter with a soft cloth before operating the unit.

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

CD ERROR CODE DESCRIPTION

	Error	Explanation
	01	When Pickup set inner position, inner switch
		cannot detect 'ON' level for 10 secs.
		When tray moves to Open/Close, Open/Close switch
	10*	cannot detect 'ON' level for 7 secs.
		When disc table rotate to target position.
		Clamp switch cannot detect 'ON' level for 7 secs.
		When disc table set to Disc1 position for 1 st time,
	11*	"CLAMP SW", "DISC NO SW" and "OPEN/CLOSE"
		cannot detect 'ON' level for 14 secs.
	31	When it changes to CD function, DSP cannot read
		initial data.

* 'CHECKING'

If Error is detected, 'CHECKING' will be display instead of 'ERCD**' display. 'ER-CD**' display will only be display when error had been detected for the 5 th times.

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.

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 “ 1 ” ( ) 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.
