Notes:
1. $1 : Power switch in “‘on” position.
2. 82 : Voltage selector switch.
(For [XA], [XB], [PA], [PE} and [PC] areas)
3. $101 : Disc holder open/close detection switch.
4. S401 : Play/pause switch.
5. S402 : Stop/clear switch.
6. S403 : Forward skip/search switch.
7. S404 : Backward skip/search switch.
8. S405 : Memory/recall switch.
9. S408 : Time mode select switch.
10. S407 : Repeat switch.
11. S408 : Open/close switch.
12. The voltage value and waveform are the reference voltage
of this unit measured by DC electronic voitmeter (high
impedance) and oscilloscope on the basis of chassis.
Accordingly, there may arise some error in voltage vatues
and waveforms depending upon the internal impedance of
the tester or the measuring unit.
* The parenthesized are the values of voltage generated
during playing (Test disc 1kHz, L+R, 0dB), others are
voitage values in stop mode.
13. Important safety notice:
Components identified by A mark have special
characteristics important for safety. When replacing any
of these components, use only manufacturer’s specified
"
: Positive voltage lines and negative voltage lines.
=z 2 Audio signal lines.
* Caution!
IC and LS! are aensitive to static electricity.
" Secondary trouble can be prevented by taking care during
repair.
%* Cover the parts boxes made of plastics with aluminum foil.
* Ground the soldering iron.
% Put a conductive mat on the work table.
* Do not touch the legs of IC or LS| with the fingers directly.
