• Voltages are taken with VOM (Input impedance 10 M
).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.

Note 1:
When the H59-DIGITAL board is defective, replace
the complete mounted board.
The mounted parts cannot be replaced with single for
repairing.
Block diagram and printed wiring board that have
been described in this service manual are for refer-
ence.
Note 2:
Among mounted electrical parts on each board, only
parts that are described in the electrical parts list can
be replaced for repairing.
The parts that are not described in the electrical parts
list cannot be replaced with single for repairing.
