All capacitors are in µF unless otherwise noted. p : µµF
50WV or less are no1 indicated except for elec1roly1ics.
All resistors are in ohms, 1/1 OW on the BT, DC, HY and HZ
boards and 1 /4W on the rest of the boards unless oterwise
specified.

D :
panel designation.
All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.
The components identified by
[;jjjjl
in this manual have been
carefully factory-selected for each se1 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 [;ii, make the
necessary adjustments indicated. If results do not mee11he
specified value, change 1he component identified by
B
and repeat the adjustment until the specified value is
achieved.
Referto R52, R53, R67, R68, R73, R75, R106, R108, R115
and R135.
Adjust on page 4-11 - 4-16.
When replacing 1he part in below table, be sure 10 parform
the related adjustment.
