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.
Ground the soldering iron.
Do not touch the pins of IC, LSI or VLSI with fingers directly.
Put a conductive mat on the work table.
The voltage value and waveforms are the reference voltage of this unit measured by DC electronic voltmeter (high impedance) and oscillo-
scope 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.
