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.
•
When replacing components identified by

,
make the necessary
adjustments by using RV501 (

)
as indicated. (See page 12)
•
All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.

When replacing parts shown in the table below,
be sure to perform the safety related adjustment.

digital multimeter
•
Readings are taken with a color-bar signal input.
•
Voltage variations may be noted due to normal
production tolerances.
