Components identified by the sign
!
have special
characteristics important for safety. When replacing any
of these components, use only the specified parts.
3. SPECIAL NOTE
All integrated circuits and many other semiconductor
devices are electrostatically sensitive and therefore
require the special handling techniques described under
the "ELECTROSTATICALLY SENSITIVE (ES) DE-
VICES" section of this service manual.
4. Parts with no Ref. No. in "EXPLODED VIEW" are not
supplied. And some Ref. No. will be skipped. Be sure to
make your orders of replacement parts according to the
