· 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 the internal impedance of the DC circuit
tester.
· Important safety notice:
Components identified
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.
· Resistor
Unit of resistance is OHM [Ω] (K=1,000, M=1,000,000).
· Capacitor
Unit of capacitance is µF, unless otherwise noted. F=Farad,
pF=Pico-Farad
· Coil
Unit of inductance is H, unless otherwise noted.
