Components identified by
; mark have special
characteristics important for safety.
·
When replacing any of components, be sure to use only
manufacture’s specified parts shown in the parts list.
·
The supply part number is described alone in the
replacement parts.
·
Voltage and signal line
: Positive voltage line
: Audio (digital) signal line
: Audio (analog) signal line
: FM signal line
: MIC signal line
·
The voltage value and waveforms are the reference voltage
of this measured by DC electronic voltmeter (high
impedance) and oscilloscope on the basis of GND terminal
(DC IN Jack). 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.
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 pins of IC or LSI with fingers directly.
