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.11-2 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
10*
11* "CLAMP SW", "DISC NO SW" and "OPEN/CLOSE"
31
* '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.
When Pickup set inner position, inner switch
cannot detect 'ON' level for 10 secs.
When tray moves to Open/Close, Open/Close switch
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,
cannot detect 'ON' level for 14 secs.
When it changes to CD function, DSP cannot read
initial data.
• FM IF
Notes:
1: Description of the "FM IF Adjustment" is not carried on this
Manual. It is because the IF coil in the FM front end section
has been best adjusted in the factory so that its further
adjustment is not needed at the field. When replacing the
FM front end assembly, no adjustment is needed either.
2: The parts in the FM front end section are prepared in a
complete unit, so you can't obtain each part individually.

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.
