B
In this manual 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 1dent1f1ed by ~- make the
necessary adjustments 1nd1cated. If results do not meet
the spec1f1ed value, change the component 1dent1f1ed by
B
and repeat the adJustment until the specified value Is
achieved.
Refer to R52, R53, R67, R68, R124, R126, R222,
R227, R228 and R239.
Adjust on page 4-13 -4-18.
When replacing the part In below table, be sure to
perform the related adjustment.
