.The voltage value and waveforms are the reference vo¡tage of this unit measured by DC electronic vollmeter (h¡gh impedance) and osc¡lloscope 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 un¡l.

.lmportance safety notice:^
Components identified by A 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 oarts shown in the oarts list.
C a u t i o n !
lC, LSI and VLSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care during repair,
.Cover the parts boxes made of olastics with aluminium foil.
.Put a conductive mat on the work table.
.Ground the soldering iron.
.Do not touch the pins of lC, LSI or VLSI with fingers directly
