Since the pickup semiconductor laser can easily damaged by 
the static electricity, handle the mechanism unit with care.
To prevent damage by the static electricity during 
transportation, the LD terminals are short-circuited at 2 points 
on the PWB. Unsolder them by a soldering iron after 
completing the connection. When you return the mechanism 
unit, solder the terminals again.

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.

 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
 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.
