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 waveformsdependingupon the internal
impedance of the tester or the measuring unit.

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. Whenreplacing 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.
