Note: The components Identified by shading and mark
A are critical for safety.
Replace
only with
part number specified.
Note:
e All capacitors are in uF unless otherwise noted. p: uF
50 WV or less are not indicated except for electrolytics.
All resistors are in ohms, 1/4 W unless otherwise noted.
kQ =1000
O,MQ =1000kQ
{Ee} :nonflamable resistor.
e [___]:panel designation.
e All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.
@ The components indentified by >€in this manual have
been carefully factory- selected for each set in order to
satisty regulations regarding X- ray radiation. Should
replacement be reguired, replace only with the value
originally used.
When replacing components identified by fd mark the
necessary adjustments indicated. If results do not meet
the specified value, change the component identified by
b4 and repeat the adjustment until the specified value is
achieved.
