The
components
indentified
by
B in this manual have been
carefully factory-selected for each
set
in
order
to
satisfy
reo
gulations regarding X·ray radiation. Should replacement be
requirad,
replace
only
with
the
value originally used.
• When replacing
componants
identified by
[;iii
mark
the
neces-
sary adjustments indicated.
If
results
do
not
meet
the
specified
value, change
the
component
identified
by
B and repeat
the
adjustmant
until
the
specified value
is
achieved.
