• When replacing components identified by
, make the necessary
adjustments indicated. If results do not meet the specified value, change
the component identified by
and repeat the adjustment until the
specified value is achieved. (Refer to
safety adjustments on Page 23.)
• When replacing the part in below table, be sure to perform the related
adjustment.

• Voltages are DC with respect to ground unless otherwise noted.
• Voltage variations may be noted due to normal production tolerances.
• All voltages are in V.

• Circled numbers are waveform references.
• The components identified by
in this basic schematic diagram have been
carefully factory-selected for each set in order to satisfy regulations regarding
X-ray radiation. Should replacement be required, replace only with the value
originally used.
