The components indantified by
B in this manual have been
carefully factory-selectee;! for aach
sat
in
order
to
satisfy re-
gulations regarding X-ray radiation. Should replacement be
required, replace
only with
the
value originally used.
When replacing components identified by

not
meet
the
specified
value, change the
component
identified by
IB
and repeat
the
adjustmant until
the
specified value
is
achieved.
