CD SECTION
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. 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.

NOTES ON SCHEMATIC DIAGRAM
• Resistor:
To differentiate the units of resistors, the 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 an
ohm resistor. The resistor designated “Fusible” is a fuse type
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.
