of PWB and laser pickup unit is not restricted.
• Automatic adjustment item
1. Focus offset (Fig. 11-1)
2. Tracking offset (Fig. 11-2)
3. E/F balance (tracking error balance) (Fig. 11-3)
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.

• The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chas-
sis 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 “ ” ( ) 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.
NOTES ON SCHEMATIC DIAGRAM
– 12 –
• Resistor:
Todifferentiatethe unitsofresistors,the symbol asKandM
are used: the symbol K means 1000 ohm and the symbol M
means1000kohm and theresistorwithoutany symbol isan
ohmresistor.Theresistordesignated“Fusible”isafusetype
resistor.
• 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.
