The voltage value and waveforms are the reference voltage of this unit measured by DC electronic voltmeter (high
l
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.

Importance safety notice :
Components identified by
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.
l
Cover the parts boxes made of plastics with aluminium foil.
l
Put a conductive mat on the work table.
l
Ground the soldering iron.
l
Do not touch the pins of IC, LSI or VLSI with fingers directly.
