The components identifi ed by X 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 necessary, replace
only with the value originally used.

only with the value originally used.
When replacing components identifi ed by Y , make the necessary
adjustments as indicated. If the results do not meet the specifi ed value,
change the component identifi ed by X and repeat the adjustment until
the specifi ed value is achieved.
(Refer to adjustments in Sections 3-1 and 3-2.)
