·The voltage value and waveforms are the reference voltage
of this unit measured by DC electronic voltmeter (high
impedance) and oscilloscope on the basis of chassis.
Accordingly, there may arise some error in voltage values
and waveforms depending upon the internal impedance of
the tester or the measuring unit.
·Battery Curent

CD: 1kHz, 0dB
FM: 60dB, 30% Mod.
AM: 74dB/m, 30% Mod.
·Importance safety notice:
Components identified by ; mark have special
characteristics important for safety. Furthermore, special
parts which have purposes of fire-retardant (resistors), high-
quality sound (capacitors), low-noise (resistors), etc. are
used. When replacing any of components, be sure to use
only manufacturer’s specified parts shown in the parts list.
Caution!
IC, LSI and VLSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care during
repair.
·Cover the parts boxes made of plastics with aluminium
foil.
·Put a conductive mat on the work table.
·Ground the soldering iron.
·Do not touch the pins of IC, LSI or VLSI with fingers
directly.
·Indicated voltage values are the standard values for the unit
measured by the DC electronic circuit tester (high-
impedance) with the chassis taken as standard. Therefore,
there may exist some errors in the voltage values,
depending on theinternalimpedanceof the DC circuit tester.
·No mark: All VR is set as a center position.

Components identified by mark have special
characteristics important for safety.
Furthermore, special parts which have purpose of fire-
retardant (resistors), high-quality sound (capacitors), low-
noise (resistors), etc. are used. When replacing any of
components, be sure to use only manufacture´s specified
parts shownintheparts list.
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.
