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

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 indicated. (See page 9)
• When replacing the part in below table, be sure to perform the
related adjustment.
