When replacing any of components, be sure to use only
manufacturer's specified parts shown in the parts list.
· The supply part number is described alone in the
replacement parts list.
· Voltage and signal line
: Positive voltage line
: Main (CD, FM) signal line
: FM signal line
: CD Playback signal line
· Circuit voltage and waveform described herein shall be
regarded as reference information when probing defect
point, because it may differ from an actual measuring value
due to difference of Measuring instrument and its
measuring condition and product itself.
Measurement conditions:
− − − − AC adaptor is used for power supply.
− − − − Set the hold switch to ON.

Caution!
IC and LSI are sensitive 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 LSI with the fingers directly.
